SQL injection in Fortinet FortiAnalyzer and FortiManager (including Cloud variants) allows an authenticated attacker to execute arbitrary commands on the underlying system via crafted requests. Affected versions include FortiAnalyzer 7.6.0-7.6.4, 7.4.0-7.4.7, and all 7.2 releases, plus FortiManager 7.6.0-7.6.4, 7.4.0-7.4.6, and all 7.2 releases, as well as FortiAnalyzer Cloud 7.6.2-7.6.4, 7.4.1-7.4.7, 7.2.1-7.2.11 and FortiManager Cloud 7.6.2-7.6.4. The vulnerability requires valid credentials; the provided CVSS vector indicates high privileges (PR:H) while the description and independent assessment suggest low privileges (PR:L) may suffice. No public exploit code or active exploitation is identified at time of analysis, and the risk is considered elevated but not an emergency based on current signals.
Authenticated SQL injection in the Fortinet FortiAnalyzer and FortiManager management platforms allows a logged-in low-privileged user to execute arbitrary commands on the appliance via crafted requests. Affected firmware covers FortiAnalyzer 7.6.0 through 7.6.4, 7.4.0 through 7.4.7 and all 7.2 releases, plus FortiManager 7.6.0 through 7.6.4, 7.4.0 through 7.4.6 and all 7.2 releases. Exploitation requires a valid account on the management interface - the vendor CVSS vector marks PR:H while the description and independent assessment indicate a low-privileged user suffices - and no public exploit code or confirmed active exploitation (CISA KEV) was identified at time of analysis, so the main risk mitigation is limiting who can reach and authenticate to the management plane.
Path traversal in Fortinet FortiSIEM 7.5.0 can let a remote unauthenticated attacker execute unauthorized code or commands by sending specially crafted packets to the affected service. The CVSS vector shows network exploitation with low complexity, no privileges, and no user interaction, producing high confidentiality, integrity, and availability impact. No public exploit code or confirmed active exploitation was identified in the provided intelligence; consult Fortinet advisory FG-IR-26-180 for the authoritative affected-version and remediation details.
Unauthenticated path traversal in Fortinet FortiMail (7.2.0-7.2.9, 7.4.0-7.4.8, 7.6.0-7.6.6 and 8.0.0-8.0.1) lets a remote attacker write arbitrary files on the underlying system via crafted HTTP or HTTPS requests, yielding CVSS 9.8 with full confidentiality, integrity and availability impact. CISA has added the CVE to its Known Exploited Vulnerabilities catalog, so it is confirmed actively exploited (CISA KEV), and publicly available exploit code exists, making unpatched internet-reachable gateways an urgent remediation priority. Exploitation requires only that the FortiMail HTTP/HTTPS interface be network-reachable - no authentication (PR:N) and no user interaction (UI:N) - so environments that confine management/web access to trusted networks or a VPN substantially reduce exposure.
UI redress (clickjacking) in the Fortinet FortiPAM Chrome Extension allows an attacker-controlled web page to frame or overlay the extension's rendered interface so that a victim's clicks are redirected into unintended, privileged extension actions, resulting in information disclosure with limited integrity impact. The affected code is the 7.4 branch and the 8.0 builds through 8.0.0 as scoped by Fortinet advisory FG-IR-26-168 (the vendor description covers all 8.0 and 7.4 versions, while ENISA EUVD specifically lists 8.0.1). Exploitation is remote and unauthenticated from the attacker's side (PR:N, CVSS:3.1/AV:N/AC:L/S:C) but is gated by required victim interaction (UI:R) - the user must have the vulnerable extension installed and be lured into clicking within an attacker-planted frame, which materially limits real-world exploitability despite Fortinet's 9.6 score; no public exploit code has been identified at time of analysis, the issue is not in CISA KEV, and the assessed impact (C:H/I:L/A:N) is lower than the vendor rating.
Sensitive information embedded in the source code of Fortinet FortiMonitorOnSight (7.2.0-7.2.2 and 7.2.4-7.2.7) can be recovered by an attacker and leveraged to bypass access controls. The exposed data (CWE-540) may include credentials, keys, or other secrets that grant unauthorized access to protected functionality. No public exploit is identified at time of analysis, and the CVE's own attack-vector text is an unfilled placeholder, so the exact delivery path is not documented by the vendor.
Improper certificate hostname validation (CWE-297) in Fortinet FortiOS and FortiProxy enables network-adjacent attackers to conduct man-in-the-middle attacks against outbound TLS connections made by affected devices. Fortinet FortiOS versions 7.6.1 through 7.6.6 and FortiProxy 7.6.2 through 7.6.6 fail to verify that a presented certificate matches the intended hostname, allowing a suitably positioned attacker to intercept and potentially tamper with encrypted traffic. Proof-of-concept code exists (E:P in temporal CVSS), and an official fix has been released per vendor advisory FG-IR-26-174.
Unauthenticated remote access control bypass in Fortinet FortiSandbox 4.2.x through 5.0.x - and its Cloud and PaaS variants - allows network-reachable attackers to retrieve sensitive information and disrupt availability by sending crafted HTTP requests, with no credentials or user interaction required. Fortinet's confirmed CVSS temporal metrics include E:P (proof-of-concept exploit code exists) alongside RL:O (official remediation available) and RC:C (confirmed), establishing this as an actively documented, patchable risk against sandboxing infrastructure that processes enterprise malware submissions. The scope-changed vector (S:C) combined with high availability impact (A:H) indicates the access control failure cascades beyond the directly targeted HTTP endpoint to other components within the FortiSandbox platform.
Command injection in Fortinet FortiSandbox allows a remote, highly privileged attacker to execute arbitrary OS commands on the underlying system, achieving full confidentiality, integrity, and availability compromise. Affected versions span FortiSandbox 4.2.1-4.2.8, 4.4.0-4.4.9, 5.0.0-5.0.6, and 5.2.0, covering a wide release range across multiple major branches. The temporal CVSS metrics (E:F/RL:O/RC:C) confirm that a functional exploit exists and an official patch has been released, making prompt patching the priority action.
Log-record tampering in Graylog's FortiGate syslog parser enables unauthenticated network senders to overwrite or erase critical security-log fields - including srcip, dstip, date, time, and tz - or cause entire log messages to be silently discarded, creating a viable log-evasion primitive. Affected are Graylog Server versions prior to 6.3.12, 7.0.7, and 7.1.2 (all branches), and Graylog Forwarder prior to version 7.3, on any deployment ingesting FortiGate key-value syslog. No public exploit code exists and this is not in CISA KEV, but the attack requires no authentication and minimal crafting skill, making it a realistic threat to security-monitoring integrity in FortiGate-centric environments.
Remote code execution in Fortinet FortiClientWindows affects versions 7.2.0-7.2.11 and 7.4.0-7.4.3, exploitable by any attacker capable of intercepting or forging DNS responses destined for the target host. Maliciously crafted DNS response packets trigger a classic buffer overflow (CWE-120) in the client's DNS parsing logic, allowing arbitrary code execution without requiring any credentials or user interaction. No public exploit or CISA KEV listing has been identified at time of analysis, and the high attack complexity requirement (DNS MITM/poisoning position) meaningfully limits opportunistic exploitation.
Authentication bypass in Fortinet FortiManager and FortiManager Cloud allows unauthenticated remote attackers to circumvent access controls via an alternate path or channel, potentially gaining full administrative control over managed security infrastructure. Affected version ranges span FortiManager 7.2.5 through 7.6.1 and FortiManager Cloud 7.2.5 through 7.6.1, covering multiple active release branches of this centralized network security management platform. No CISA KEV listing or confirmed public exploit has been identified at time of analysis, but the unauthenticated network vector combined with full C/I/A impact and the high-value nature of the target - a platform governing firewall policy across entire enterprise estates - elevates real-world priority significantly beyond the AC:H qualifier alone.
Authentication bypass in Fortinet FortiWeb (versions 7.0.0-7.0.12, 7.2.0-7.2.12, 7.4.0-7.4.11, 7.6.0-7.6.6, and 8.0.0-8.0.2) lets a remote unauthenticated attacker log into the GUI/CLI management interface using an arbitrary, made-up username and password, granting full administrative control of the web application firewall. Tracked as CVE-2026-26035 (EUVD-2026-57193) and rated CVSS 9.8, this is an improper-authentication (CWE-287) flaw reported by Fortinet's own PSIRT (FG-IR-26-158). There is no public exploit identified at time of analysis and it is not on the CISA KEV list, but the trivial exploitability and network exposure make it a high-priority patch.
Stack-based buffer overflow in Fortinet FortiOS, FortiProxy, and FortiPAM allows unauthenticated remote attackers to execute arbitrary code or commands within the WAD (Web Application Daemon) process via crafted sockets - but only on devices where the explicit proxy is simultaneously configured with Kerberos authentication and SOCKS enabled. Exploitation further requires defeating stack canary protection and ASLR, elevating real-world attack complexity well above the raw CVSS base score implies. No public exploit or active exploitation has been confirmed; Fortinet PSIRT published advisory FG-IR-26-161 disclosing the issue.
Improper TLS certificate validation in Fortinet FortiClientEMS (Endpoint Management Server) exposes sensitive information to network-positioned attackers across FortiClientEMS 7.2 (all listed builds up to 7.2.14), 7.4.0–7.4.1, and 7.4.3–7.4.5. Because the client fails to properly verify server certificates (CWE-295), an attacker able to intercept EMS communications can decrypt or observe protected traffic to disclose information. There is no public exploit identified at time of analysis and CISA SSVC scores exploitation as 'none', but Fortinet rates the flaw CVSS 9.8, so patching should be prioritized despite the lack of observed exploitation.
Privilege escalation in Fortinet FortiSIEM Windows Agent 7.4.0 through 7.4.1 stems from an improper restriction of the agent's communication channel (CWE-923), letting an adjacent-network attacker interact with an endpoint that should be limited to trusted parties and thereby gain elevated privileges with full confidentiality, integrity, and availability impact. The flaw was disclosed by Fortinet PSIRT (FG-IR-26-155) and carries a CVSS 7.5 rating; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. Exploitation is gated by high attack complexity, which materially reduces real-world likelihood despite the unauthenticated vector.
Exposure of a scanning VM's VNC service in Fortinet FortiSandbox 5.0.0-5.0.2 and 4.4.3-4.4.8 lets an unauthenticated remote attacker reach the VNC server of the sandbox virtual machines used for malware detonation via ordinary network requests. Because these VMs run and observe live malware samples, unauthorized VNC access can expose sensitive analysis sessions and potentially allow interaction with the detonation environment. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Unauthenticated OS command injection in Fortinet FortiSandbox (on-premise, Cloud, and PaaS variants) allows remote attackers to execute arbitrary operating system commands by sending specifically crafted HTTP requests to the management interface. The flaw carries a CVSS 9.8 rating with network-reachable, no-authentication, no-user-interaction characteristics, and no public exploit identified at time of analysis. Because FortiSandbox is a security-analysis appliance handling untrusted samples, compromise undermines the integrity of malware verdicts and downstream detections.
Critical unauthenticated access control bypass in Fortinet FortiAuthenticator versions 6.5.0-6.5.6, 6.6.0-6.6.8, 8.0.0, and 8.0.2 enables remote code execution without authentication. The CVSS score of 9.8 with AV:N/AC:L/PR:N/UI:N indicates trivial remote exploitation against default configurations. While the vendor advisory (FG-IR-26-128) confirms this vulnerability, the incomplete description placeholder ('<insert attack vector here>') suggests the advisory may contain additional details not yet published in CVE records. No public exploit code or active exploitation confirmed at time of analysis, though the authentication bypass nature and maximum CVSS scores make this a priority patching target for organizations running FortiAuthenticator.
Remote code execution in Fortinet FortiSandbox 4.4.x through 5.0.x (on-premises, Cloud, and PaaS deployments) allows unauthenticated attackers to execute arbitrary code or commands via crafted HTTP requests. This CWE-862 missing authorization flaw affects sandbox analysis appliances across multiple deployment models with CVSS 9.8 (critical) severity. Fortinet has published vendor advisory FG-IR-26-136. No CISA KEV listing or public POC identified at time of analysis, though the trivial attack complexity (AC:L) and network vector without authentication (PR:N) indicate high exploitability if technical details emerge.
Out-of-bounds write in FortiWeb administrative interface enables authenticated remote code execution on web application firewall appliances. Affects FortiWeb 7.4.0-7.4.11, 7.6.0-7.6.6, and 8.0.0-8.0.3. CVSS 7.2 indicates high-privilege authenticated network attack with low complexity. No public exploit identified at time of analysis, though the incomplete advisory description ('<insert attack vector here>') suggests disclosure may be pending or sanitized. Memory corruption class (CWE-787) typically enables arbitrary code execution, confirmed by CVSS impact ratings (High C/I/A). EPSS data not available for risk probability assessment.
Path traversal vulnerability in Fortinet FortiOS, FortiProxy, FortiPAM, and FortiSwitchManager allows authenticated administrators with read-write permissions to write or delete arbitrary files via malicious CLI commands, potentially compromising system integrity and availability across multiple Fortinet product lines. The vulnerability affects FortiOS 6.4 through 7.6.4, FortiProxy 7.0 through 7.6.4, FortiPAM 1.0 through 1.7.0, and FortiSwitchManager 7.0 through 7.2.7. With a CVSS score of 6.0 a
Path traversal in Fortinet FortiSandbox 4.4.0-4.4.8 and 5.0.0-5.0.5 enables remote unauthenticated attackers to achieve full system compromise. With CVSS 9.8 (AV:N/AC:L/PR:N/UI:N), the vulnerability permits network-based exploitation without credentials or user interaction, leading to complete confidentiality, integrity, and availability impact. Despite critical severity, EPSS score of 0.06% (18th percentile) indicates low observed exploitation probability. No active exploitation confirmed (not in CISA KEV). SSVC framework marks it as automatable with total technical impact but no current exploitation. The incomplete CVE description (placeholder text for attack vector) suggests early disclosure; verify completeness with Fortinet advisory FG-IR-26-112.
Remote code execution in Fortinet FortiAnalyzer Cloud and FortiManager Cloud versions 7.6.2 through 7.6.4 allows unauthenticated remote attackers to execute arbitrary code via crafted network requests exploiting a heap-based buffer overflow (CWE-122). Attack complexity is rated high due to ASLR and network segmentation defenses requiring significant exploitation preparation. CVSS score of 8.1 reflects the critical impact despite defensive barriers. No public exploit identified at time of analysis, though the vulnerability's disclosure by Fortinet suggests patch availability through their security advisory FG-IR-26-121.
SQL injection in Fortinet FortiDDoS-F 7.2.1-7.2.2 allows authenticated remote attackers to execute unauthorized code or commands with high impact to confidentiality, integrity, and availability. The vulnerability resides in the web management interface and requires low attack complexity with no user interaction. No public exploit identified at time of analysis, with EPSS data not yet available for this recently disclosed CVE.
Authentication bypass in Fortinet FortiSOAR allows unauthenticated remote attackers to circumvent two-factor authentication (2FA) protections via replay attacks against intercepted authentication tokens. Affects both PaaS and on-premise deployments of FortiSOAR versions 7.5.0-7.5.2 and 7.6.0-7.6.3. Successful exploitation requires network positioning to intercept and decrypt authentication traffic, then replay captured 2FA requests before token expiration (CVSS:3.1/AV:N/AC:H/PR:N/UI:R). EPSS data not available; no public exploit code or CISA KEV listing identified at time of analysis, though the precise attack requirements (traffic interception, decryption, timing) increase complexity beyond simple network access.
Fortinet FortiSOAR transmits sensitive information in cleartext over the network, allowing authenticated remote attackers to disclose confidential data. The vulnerability affects both PaaS and on-premise deployments across versions 7.3 through 7.6.x, with CVSS 6.5 reflecting moderate confidentiality impact requiring low-privilege authentication. No public exploit code or active exploitation has been confirmed at time of analysis.
OS command injection in Fortinet FortiSandbox 4.4.0-4.4.8 and FortiSandbox PaaS versions 21.3-23.4 enables remote unauthenticated attackers to execute arbitrary system commands with complete system compromise. CVSS 9.8 (network, low complexity, no privileges) but EPSS 0.29% (53rd percentile) suggests limited real-world exploitation observed despite maximum severity score. No active exploitation confirmed (not in CISA KEV). SSVC framework classifies as automatable with total technical impact but no known exploitation. Fortinet PSIRT advisory FG-IR-26-100 available but description incomplete (missing attack vector specifics).
Remote code execution in Fortinet FortiClientEMS versions 7.4.5 through 7.4.6 allows unauthenticated attackers to execute arbitrary code via crafted network requests. The vulnerability stems from improper access control (CWE-284) and requires no user interaction or privileges (CVSS PR:N). With a CVSS score of 9.1 (Critical) and low attack complexity, this represents a severe exposure for organizations using affected FortiClientEMS versions. The CVSS temporal metrics indicate functional exploit code exists (E:F) with an official fix available (RL:O), making this a high-priority patching target despite no confirmed active exploitation (not present in CISA KEV).
Fortinet FortiSandbox Cloud 5.0.4 contains an OS command injection vulnerability that allows privileged super-admin users with CLI access to execute arbitrary code through malicious HTTP requests. The vulnerability requires high privileges and direct access but carries high impact including confidentiality, integrity, and availability compromise. No patch is currently available.

Fortinet FortiAnalyzer and FortiManager contain a critical authentication bypass vulnerability (CVE-2026-24858, CVSS 9.8) that allows unauthenticated remote attackers to gain administrative access through an alternate authentication path. With EPSS 2.8% but KEV listing confirming active exploitation, this vulnerability threatens the security management infrastructure that organizations rely on to protect their networks.
Remote code execution in Fortinet FortiOS (6.4 through 7.6.3) and FortiSwitchManager (7.0.x/7.2.x) lets an attacker run unauthorized code or commands by sending specially crafted packets to an affected device. The flaw is a heap-based buffer overflow requiring no authentication or user interaction, and it is confirmed actively exploited (CISA KEV) with publicly available exploit code, reportedly tied to a 'PivotC2' FortiGate RAT. Despite the KEV listing, EPSS is only 0.01% (2nd percentile), indicating targeted rather than mass-scanning exploitation to date.
Authentication bypass in Fortinet FortiOS, FortiProxy, and FortiSwitchManager allows unauthenticated remote attackers to defeat FortiCloud SSO login by submitting a crafted SAML response, due to improper verification of the response's cryptographic signature. The flaw is confirmed actively exploited (CISA KEV), with Arctic Wolf observing malicious SSO logins in the wild, and EPSS rates it at the 93rd percentile of likelihood. Combined with a 9.8 CVSS score and CWE-347 root cause, this is a top-priority patching target for any organization running affected Fortinet management planes.

Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
FortiOS SSL-VPN contains an improper authentication vulnerability that allows users to bypass two-factor authentication by changing the case of their username, undermining MFA security controls.
Use of a hard-coded cryptographic key to cipher sensitive data in FortiOS configuration backup file may allow an attacker with access to the backup file to decipher the sensitive data, via knowledge. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
Crafted CLI commands fed to the newcli daemon on Fortinet FortiOS - and on the related FortiProxy, FortiSwitch, FortiPAM and FortiSASE platforms that share the code base - trigger a double free that crashes the daemon, giving a local, highly privileged authenticated administrator a low-impact denial of service. Exploitation requires an interactive, already-authenticated administrative CLI session, with no remote, unauthenticated or default-configuration path; no public exploit has been identified at time of analysis. At CVSS 2.3 (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L), this is a low-priority, low-real-risk issue despite being a named CVE.
FortiSandbox and FortiSandbox Cloud ship with a hard-coded cryptographic key that is used to validate or sign trusted HTTP requests, allowing an unauthenticated remote attacker who knows that static key to craft requests the appliance treats as legitimate and thereby escalate privileges. Per the assessed vector (CVSS:3.1/AV:N/AC:L/PR:N/UI:N, official score 5.3), no valid credentials or user interaction are required once the embedded key is known, though exploitation is limited to deployments that expose the HTTP/management interface to the attacker's network. Affected versions are FortiSandbox 5.2.0-5.2.1, 5.0.0-5.0.6 and all 4.4 releases, plus the corresponding FortiSandbox Cloud versions; there is no public exploit identified at time of analysis, but the issue is authoritative-moderate severity and should be remediated rather than treated as an emergency.
Sensitive information disclosure in Fortinet FortiAnalyzer, FortiAnalyzer Cloud, and FortiManager allows an authenticated low-privileged user to extract data from the underlying database via SQL injection. Affected versions include FortiAnalyzer 7.6.0-7.6.4, 7.4.0-7.4.7, and all 7.2 versions; FortiAnalyzer Cloud 7.6.2-7.6.4, 7.4.1-7.4.7, and 7.2.1-7.2.11; and FortiManager 7.6.0-7.6.4, 7.4.0-7.4.6, and all 7.2 versions. This is a moderate-priority vulnerability due to the authentication requirement, and no public exploit code has been identified at time of analysis.
Authenticated low-privileged users can exploit an SQL injection flaw in Fortinet FortiAnalyzer and FortiAnalyzer Cloud to execute arbitrary commands on the underlying system. The vulnerability affects FortiAnalyzer 7.6.0-7.6.4, 7.4.0-7.4.7, and all 7.2 versions, as well as FortiAnalyzer Cloud 7.6.2-7.6.4, 7.4.1-7.4.7, and 7.2.1-7.2.11. The CVSS 3.1 score is 8.8 (High) with a vector requiring network access and low privileges; no public exploit code has been identified at time of analysis.
Authenticated SQL injection in Fortinet FortiMail versions 7.6.0 through 7.6.3, 7.4.0 through 7.4.5, and 7.2.0 through 7.2.8 allows an attacker with a low-privilege account to execute unauthorized code or commands via crafted HTTP/HTTPS requests to the management or webmail interface. The vulnerability requires network reachability and a valid session (PR:L) but no user interaction, with low attack complexity. No public exploit has been identified at time of analysis, but the high CVSS score (8.8) and potential for full compromise of confidentiality, integrity, and availability make it a credible priority for operators, especially if the interface is internet-facing.
Persistent denial of management access in Fortinet FortiSandbox stems from an uncaught exception (CWE-248) triggered by crafted HTTP requests sent to the appliance's GUI/CLI management interface; FortiSandbox 5.2.0 through 5.2.1, 5.0.0 through 5.0.6, and all 4.4 versions are affected. Exploitation is not unauthenticated - the CVSS vector (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H) shows a privileged account on the management interface is required, so realistic abuse is confined to insiders or misuse of already-compromised administrative credentials, and the resulting impact is limited to availability (persistent loss of GUI and CLI access) with no data exposure or modification. There is no confirmed active exploitation and no public exploit identified at time of analysis; the issue is a modest-priority availability concern rather than an emergency, with remediation guidance published in Fortinet PSIRT advisory FG-IR-26-176.
A missing authorization check in Fortinet FortiSIEM 7.5.0 lets an attacker with an already-authenticated, high-privilege account send specially crafted HTTP requests to invoke functionality they should not be authorized to reach, potentially resulting in unauthorized code or command execution. Exploitation requires an existing PR:H-level account (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:L, base 3.8), so the realistic threat is a malicious insider or an attacker who has already compromised a privileged FortiSIEM account rather than an unauthenticated outsider; confidentiality is unaffected and only low-level integrity and availability impact is scored. There is no confirmed active exploitation (not in CISA KEV) and no public exploit identified at time of analysis, keeping this a low-priority item, though its command-execution potential warrants prompt patching where privileged-account hygiene is weak.
OS command injection in Fortinet FortiManager (8.0.0 and 7.6.0-7.6.6) and FortiManager Cloud (7.6.2-7.6.6) allows a high-privileged authenticated attacker on an adjacent network to execute arbitrary operating system commands, enabling privilege escalation and potential full compromise of the management appliance. The vulnerability requires an existing administrative account (CVSS PR:H) and network adjacency (AV:A), and no public exploit identified at time of analysis. Despite the high-value nature of the target, these prerequisites substantially narrow realistic risk to post-compromise or malicious insider scenarios, consistent with the moderate-risk assessment.
Authenticated denial of service in Fortinet FortiOS, FortiPAM, and FortiProxy allows a high-privileged network attacker to crash the httpsd daemon by sending specially crafted HTTP requests, exploiting a NULL pointer dereference (CWE-476). The vulnerability spans FortiOS 7.2.x and 7.4.x, FortiProxy 7.2 through 7.6.6, and every FortiPAM release from 1.0.0 through 1.9.0. No active in-the-wild exploitation is confirmed, but the CVSS temporal metric E:P indicates proof-of-concept code exists; Fortinet has released an official fix under advisory FG-IR-26-173.
Improper access control in Fortinet FortiManager and FortiManager Cloud allows authenticated administrators to bypass the workflow session approval process via crafted HTTP or HTTPS requests (CWE-284). Affected versions span FortiManager 6.4.x through 7.6.4 and FortiManager Cloud 6.4.x through 7.6.4 per EUVD intelligence, a broader range than the base CVE description indicates. An admin who should be subject to a change-management or four-eyes approval policy can circumvent that gate, pushing unapproved configuration changes to managed FortiGate devices. No public exploit code or CISA KEV listing is identified at time of analysis.
Denial of service in Fortinet FortiAnalyzer 7.6.3 through 7.6.6 is achievable by a low-privileged remote attacker exploiting a use of uninitialized variable (CWE-457) flaw. A confirmed proof-of-concept exists per the CVSS temporal vector (E:P), and an official remediation is available per the Fortinet PSIRT advisory FG-IR-26-172. The CVE description contains a verbatim placeholder ('<insert attack vector here>') instead of the specific triggering mechanism, reducing technical precision; however, the CVSS vector (AV:N/AC:L/PR:L) confirms network-reachable exploitation requiring only low-privilege credentials. No confirmed active exploitation (CISA KEV) has been identified at time of analysis.
Improper access control (CWE-284) in Fortinet FortiSOAR allows an authenticated low-privilege user to escalate their privileges within the platform via an undisclosed attack vector. Both PaaS and on-premise deployments across FortiSOAR versions 7.3 through 7.6.6 are affected. No public exploit or CISA KEV listing is present at time of analysis; the Fortinet PSIRT advisory FG-IR-26-164 is the sole authoritative source.
Open redirect (CWE-601) in Fortinet FortiSIEM 7.4.1-7.5.1 allows unauthenticated remote attackers to redirect FortiSIEM users to attacker-controlled sites via a crafted URL, enabling phishing or credential-harvesting attacks against security operations personnel. The CVSS temporal score includes E:P (proof of concept exists) and RL:O (official fix available), per Fortiguard advisory FG-IR-26-169. No active exploitation confirmed and no KEV listing; the overall risk is constrained by AC:H and mandatory user interaction, yielding a low base score of 2.8.
Unverified ownership checks in Fortinet FortiClientWindows allow a locally authenticated administrator to perform improper access control operations, resulting in high availability impact and minor integrity modification of the endpoint security client. Affected versions are FortiClientWindows 7.4.0 through 7.4.7 and 7.2.0 through 7.2.15 on Windows endpoints. No public exploit or active exploitation has been identified; the attack surface is substantially constrained by the local-only, high-privilege prerequisite.
Unauthenticated access control bypass in Fortinet FortiWeb - spanning the 7.0 line through 8.0.2 - and multiple FortiOS branches stems from an incomplete list of disallowed inputs (CWE-184), allowing remote attackers to circumvent input-filtering enforcement and achieve unauthorized integrity modifications. The vulnerability extends to FortiOS, implicating shared blocklist logic across Fortinet's platform stack according to EUVD-2026-57192 and CPE data. Publicly available exploit code exists (CVSS temporal E:P), an official fix has been released (RL:O/RC:C), and no active exploitation has been confirmed in the CISA KEV catalog at time of analysis.
Server-side request forgery in Fortinet FortiSIEM across an extensive version range (6.4.x through 7.5.0) permits authenticated high-privileged attackers to force the server to issue unauthorized requests to internal or external resources, enabling potential lateral movement to internal network services and limited information disclosure. The CVSS base score of 3.4 reflects the dominant mitigating factor of mandatory high-privilege authentication (PR:H), confining exploitation to insiders or post-compromise scenarios. The CVSS temporal metric E:P confirms proof-of-concept exploit code exists, though no CISA KEV listing indicates active widespread exploitation at time of analysis.
Denial-of-service risk in Fortinet FortiOS across five major version branches (6.4.x through 7.6.6) stems from unbounded resource allocation (CWE-770), allowing unauthenticated remote attackers to degrade availability of affected network appliances. The CVSS temporal metric E:P confirms proof-of-concept exploit code exists, and an official patch is available per Fortinet PSIRT advisory FG-IR-26-162. No active exploitation is confirmed in CISA KEV at time of analysis, but the broad version coverage and perimeter-facing nature of FortiOS appliances elevate practical risk.
Stored or reflected cross-site scripting in Fortinet FortiSIEM's web interface enables a high-privileged authenticated attacker to inject malicious script tags that execute in the browsers of other users who view the affected page. The vulnerability spans a wide version range from FortiSIEM 6.4 through 7.4.0, affecting all deployments of this enterprise SIEM platform. No active exploitation has been confirmed by CISA KEV, and no public exploit code is identified at time of analysis; the PR:H requirement meaningfully constrains real-world attacker opportunity despite the scope change to the victim's browser context.
Buffer over-read in Fortinet FortiOS and FortiProxy exposes sensitive memory contents to authenticated network attackers across multiple product lines including FortiPAM and FortiSwitchManager. The flaw, rooted in CWE-126 (buffer over-read), allows low-privileged remote users to read beyond allocated buffer boundaries, resulting in partial information disclosure with no integrity or availability impact. No active exploitation confirmed in CISA KEV, but the CVSS temporal vector includes E:P indicating proof-of-concept exploit code exists, and an official fix is available per RL:O.
FortiOS across the 7.2, 7.4, and 7.6 release trains leaks portions of device runtime memory to authenticated remote attackers via a buffer over-read in redirect response handling. Exploitation requires valid credentials but no elevated privileges, and proof-of-concept code exists (CVSS temporal E:P). An official vendor fix is confirmed available (RL:O), though unpatched instances of FortiOS 7.2.x, 7.4.0-7.4.8, and 7.6.0-7.6.2 remain at risk of sensitive memory disclosure - a consequential exposure given that FortiOS processes session tokens, credentials, and cryptographic material at runtime.
Reflected or stored cross-site scripting in Fortinet FortiOS, FortiPAM, and FortiProxy web interfaces allows a remote unauthenticated attacker to execute JavaScript in the browser session of an authenticated administrator via crafted HTTP requests. The CVSS temporal metric E:P confirms publicly available proof-of-concept exploit code exists, and the RL:O metric confirms Fortinet has released an official fix. No active exploitation has been confirmed by CISA KEV at time of analysis, but the combination of a POC and the high-value targets (network security appliances and privileged access management systems) elevates real-world risk beyond what the base CVSS score of 6.1 suggests.
Path traversal (CWE-22) in Fortinet FortiOS, FortiProxy, and FortiPAM enables a highly-privileged, physically-present attacker to execute unauthorized code or commands by escaping restricted directory boundaries. The vendor-supplied CVSS vector (AV:P/PR:H) constrains exploitation to scenarios requiring both physical device access and high-level credentials, making opportunistic or remote mass exploitation implausible. A proof-of-concept exists per the CVSS temporal indicator (E:P), and Fortinet has released an official fix per PSIRT advisory FG-IR-26-151; this vulnerability is not currently listed in the CISA KEV catalog.
HTTP Response Splitting in Fortinet FortiOS and FortiProxy captive portal authentication flows enables a man-in-the-middle attacker to inject arbitrary HTTP headers into intercepted authentication requests. Affected platforms span FortiOS 7.2-7.6.4 and FortiProxy 7.2-7.6.4. The CVSS temporal vector includes E:P, confirming proof-of-concept exploit code exists; however, no active exploitation has been confirmed via CISA KEV. The RL:O temporal indicator confirms an official remediation is available per vendor advisory FG-IR-26-153.
HTTP Response Splitting in Fortinet FortiOS and FortiProxy enables an attacker who holds a valid web filter override token to inject arbitrary HTTP headers into server responses by tricking a user into clicking a crafted link. Affected versions span FortiOS 7.2 through 7.6.4 and FortiProxy 7.2 through 7.6.4. No active exploitation has been confirmed by CISA KEV, though the CVSS temporal vector includes E:P, indicating partial proof-of-concept evidence exists. Real-world impact is constrained by the requirement to possess a valid web filter override token and to achieve user interaction.
Information disclosure in Fortinet FortiAuthenticator (6.5 all versions and 6.6.0–6.6.2) lets a remote unauthenticated attacker read out-of-bounds memory via a specially crafted request, exposing sensitive in-memory data. The CVSS temporal metrics (E:F, RC:C) indicate a functional, confirmed exploit is understood by the vendor, and an official fix is available (RL:O). No CISA KEV listing is present, so this is not confirmed as actively exploited despite the mature exploit signal.
Stack-based buffer overflow in Fortinet FortiOS, FortiPAM, FortiProxy, and FortiSASE enables arbitrary code execution for a privileged authenticated attacker capable of bypassing ASLR and stack canary protections via crafted HTTP requests. The CVSS temporal metric E:P confirms proof-of-concept exploit code exists, and RL:O confirms an official patch has been released by Fortinet (advisory FG-IR-26-148). This vulnerability is not listed in CISA KEV at time of analysis, and the dual prerequisites of privileged access plus memory-protection bypass substantially constrain real-world exploitability despite the critical CIA impact triad.
Fortinet FortiOS and FortiProxy expose an internal debug interface (CWE-1244) that allows authenticated administrators to execute arbitrary Lua scripts through crafted CLI commands, exceeding their intended administrative scope. The vulnerability spans broad version ranges of both products, including FortiOS 6.4 through 7.6.2 and FortiProxy 7.0 through 7.6.3. While exploitation requires existing high-privilege (admin) access - limiting opportunistic attack surface - the CVSS temporal vector (E:P) confirms a proof-of-concept exploit exists, and the official fix is available (RL:O). No public exploit identified at time of analysis beyond the proof-of-concept, and this vulnerability is not listed in CISA KEV.
Improper access control in Fortinet FortiPortal versions 7.0.x (all), 7.2.0-7.2.8, and 7.4.0-7.4.7 enables an authenticated low-privilege attacker to bypass authorization controls and gain unauthorized read access to sensitive data. The CVSS vector (AV:N/AC:L/PR:L/UI:N/C:H) indicates low-complexity network exploitation by any authenticated user, resulting in high confidentiality impact with no integrity or availability loss. No public exploit identified at time of analysis based on CISA KEV, though publicly available exploit code exists per the CVSS temporal E:P metric, and Fortinet has issued an official fix.
OS command injection in Fortinet FortiAP and FortiAP-W2 access points allows authenticated administrators to execute arbitrary code or commands via specially crafted CLI commands. Affected versions span FortiAP 6.4 through 7.6.2 and FortiAP-W2 7.0 through 7.4.4. The vulnerability requires high-privilege administrative access and does not require user interaction, making it exploitable by rogue administrators or accounts with compromised credentials. No public exploit code or active exploitation has been identified at time of analysis.
OS command injection in Fortinet FortiAP, FortiAP-U, and FortiAP-W2 allows authenticated privileged attackers to execute arbitrary code via maliciously crafted CLI requests. Affected versions span FortiAP 6.4 through 7.6.2, FortiAP-U 6.2 through 7.0.5, and FortiAP-W2 7.0 through 7.4.4. The vulnerability requires high-privilege administrative access and local CLI interaction, limiting exposure to trusted insider threats or compromised management interfaces. CVSS 6.1 reflects the high impact (code execution with full system privileges) constrained by authentication and local access requirements.
Denial-of-service attacks against Fortinet FortiAnalyzer and FortiManager 6.4 through 7.6.4 allow authenticated attackers to trigger system hangs via specially crafted HTTP requests that exploit a use of potentially dangerous function vulnerability (CWE-676). The crash occurs only when internal lock alignment conditions are met, making exploitation dependent on timing and system state rather than attacker control. CVSS 5.2 reflects medium severity with high attack complexity and low availability impact; active exploitation is not confirmed.
SQL injection in FortiMail 7.2.0-7.2.8, 7.4.0-7.4.5, and 7.6.0-7.6.3 allows authenticated privileged administrators to execute arbitrary code or commands via crafted HTTP/HTTPS requests. The vulnerability requires high-privilege authentication (administrator role) and affects all recent major versions, with exploitation confirmed possible through network-accessible admin interfaces.
Argument injection in Fortinet FortiDeceptor 5.0 through 6.0.2 allows authenticated administrators with read-only permissions to read arbitrary log files via crafted HTTP requests, exposing sensitive system and audit logs. The vulnerability requires valid admin credentials but no elevated privileges, making it accessible to lower-privileged authenticated users. No public exploit code or active exploitation has been confirmed at time of analysis.
Remote code execution in Fortinet FortiOS 7.2.0-7.2.11, 7.4.0-7.4.8, and 7.6.0-7.6.3 enables authenticated attackers to execute arbitrary code via malformed network packets. The out-of-bounds write vulnerability (CWE-787) affects FortiOS firewall appliances and requires only low-privilege credentials to exploit over the network. Fortinet published advisory FG-IR-26-123 confirming the vulnerability. No CISA KEV listing or public exploit code identified at time of analysis, though the straightforward network attack vector (AV:N/AC:L) suggests moderate weaponization potential once details emerge.
Improper export of Android application components in Fortinet FortiToken Android 5.2, 6.1, and 6.2 allows local authenticated attackers to gain unauthorized access to sensitive information via exposed application components that lack proper access control. The vulnerability has a CVSS score of 5.0 with local attack vector and requires low privileges, enabling information disclosure without user interaction. No public exploit code has been identified, and the vulnerability is not listed in active exploitation databases at the time of analysis.
Fortinet FortiClient Windows versions 7.2 (all) and 7.4.0 through 7.4.2 contain a hard-coded cryptographic key vulnerability that allows high-privileged local attackers to disclose sensitive information. The vulnerability requires local access and administrator-level privileges, limiting its real-world exploitation scope to threats already present on compromised systems or malicious insiders. No public exploit code or active exploitation has been confirmed at the time of analysis.
SQL injection in Fortinet FortiNDR 7.0 through 7.6.2 allows authenticated attackers to execute unauthorized code or commands via crafted HTTP requests. The vulnerability affects multiple versions across the 7.x branch and has an EPSS exploitation probability indicator (E:P in CVSS), suggesting feasible attack conditions despite moderate CVSS score (5.1). Patch availability and active exploitation status require confirmation from vendor advisory.
SQL injection in Fortinet FortiAnalyzer and FortiManager (including Cloud variants) allows an authenticated attacker to execute arbitrary commands on the underlying system via crafted requests. Affected versions include FortiAnalyzer 7.6.0-7.6.4, 7.4.0-7.4.7, and all 7.2 releases, plus FortiManager 7.6.0-7.6.4, 7.4.0-7.4.6, and all 7.2 releases, as well as FortiAnalyzer Cloud 7.6.2-7.6.4, 7.4.1-7.4.7, 7.2.1-7.2.11 and FortiManager Cloud 7.6.2-7.6.4. The vulnerability requires valid credentials; the provided CVSS vector indicates high privileges (PR:H) while the description and independent assessment suggest low privileges (PR:L) may suffice. No public exploit code or active exploitation is identified at time of analysis, and the risk is considered elevated but not an emergency based on current signals.
Authenticated SQL injection in the Fortinet FortiAnalyzer and FortiManager management platforms allows a logged-in low-privileged user to execute arbitrary commands on the appliance via crafted requests. Affected firmware covers FortiAnalyzer 7.6.0 through 7.6.4, 7.4.0 through 7.4.7 and all 7.2 releases, plus FortiManager 7.6.0 through 7.6.4, 7.4.0 through 7.4.6 and all 7.2 releases. Exploitation requires a valid account on the management interface - the vendor CVSS vector marks PR:H while the description and independent assessment indicate a low-privileged user suffices - and no public exploit code or confirmed active exploitation (CISA KEV) was identified at time of analysis, so the main risk mitigation is limiting who can reach and authenticate to the management plane.
Path traversal in Fortinet FortiSIEM 7.5.0 can let a remote unauthenticated attacker execute unauthorized code or commands by sending specially crafted packets to the affected service. The CVSS vector shows network exploitation with low complexity, no privileges, and no user interaction, producing high confidentiality, integrity, and availability impact. No public exploit code or confirmed active exploitation was identified in the provided intelligence; consult Fortinet advisory FG-IR-26-180 for the authoritative affected-version and remediation details.
Unauthenticated path traversal in Fortinet FortiMail (7.2.0-7.2.9, 7.4.0-7.4.8, 7.6.0-7.6.6 and 8.0.0-8.0.1) lets a remote attacker write arbitrary files on the underlying system via crafted HTTP or HTTPS requests, yielding CVSS 9.8 with full confidentiality, integrity and availability impact. CISA has added the CVE to its Known Exploited Vulnerabilities catalog, so it is confirmed actively exploited (CISA KEV), and publicly available exploit code exists, making unpatched internet-reachable gateways an urgent remediation priority. Exploitation requires only that the FortiMail HTTP/HTTPS interface be network-reachable - no authentication (PR:N) and no user interaction (UI:N) - so environments that confine management/web access to trusted networks or a VPN substantially reduce exposure.
UI redress (clickjacking) in the Fortinet FortiPAM Chrome Extension allows an attacker-controlled web page to frame or overlay the extension's rendered interface so that a victim's clicks are redirected into unintended, privileged extension actions, resulting in information disclosure with limited integrity impact. The affected code is the 7.4 branch and the 8.0 builds through 8.0.0 as scoped by Fortinet advisory FG-IR-26-168 (the vendor description covers all 8.0 and 7.4 versions, while ENISA EUVD specifically lists 8.0.1). Exploitation is remote and unauthenticated from the attacker's side (PR:N, CVSS:3.1/AV:N/AC:L/S:C) but is gated by required victim interaction (UI:R) - the user must have the vulnerable extension installed and be lured into clicking within an attacker-planted frame, which materially limits real-world exploitability despite Fortinet's 9.6 score; no public exploit code has been identified at time of analysis, the issue is not in CISA KEV, and the assessed impact (C:H/I:L/A:N) is lower than the vendor rating.
Sensitive information embedded in the source code of Fortinet FortiMonitorOnSight (7.2.0-7.2.2 and 7.2.4-7.2.7) can be recovered by an attacker and leveraged to bypass access controls. The exposed data (CWE-540) may include credentials, keys, or other secrets that grant unauthorized access to protected functionality. No public exploit is identified at time of analysis, and the CVE's own attack-vector text is an unfilled placeholder, so the exact delivery path is not documented by the vendor.
Improper certificate hostname validation (CWE-297) in Fortinet FortiOS and FortiProxy enables network-adjacent attackers to conduct man-in-the-middle attacks against outbound TLS connections made by affected devices. Fortinet FortiOS versions 7.6.1 through 7.6.6 and FortiProxy 7.6.2 through 7.6.6 fail to verify that a presented certificate matches the intended hostname, allowing a suitably positioned attacker to intercept and potentially tamper with encrypted traffic. Proof-of-concept code exists (E:P in temporal CVSS), and an official fix has been released per vendor advisory FG-IR-26-174.
Unauthenticated remote access control bypass in Fortinet FortiSandbox 4.2.x through 5.0.x - and its Cloud and PaaS variants - allows network-reachable attackers to retrieve sensitive information and disrupt availability by sending crafted HTTP requests, with no credentials or user interaction required. Fortinet's confirmed CVSS temporal metrics include E:P (proof-of-concept exploit code exists) alongside RL:O (official remediation available) and RC:C (confirmed), establishing this as an actively documented, patchable risk against sandboxing infrastructure that processes enterprise malware submissions. The scope-changed vector (S:C) combined with high availability impact (A:H) indicates the access control failure cascades beyond the directly targeted HTTP endpoint to other components within the FortiSandbox platform.
Command injection in Fortinet FortiSandbox allows a remote, highly privileged attacker to execute arbitrary OS commands on the underlying system, achieving full confidentiality, integrity, and availability compromise. Affected versions span FortiSandbox 4.2.1-4.2.8, 4.4.0-4.4.9, 5.0.0-5.0.6, and 5.2.0, covering a wide release range across multiple major branches. The temporal CVSS metrics (E:F/RL:O/RC:C) confirm that a functional exploit exists and an official patch has been released, making prompt patching the priority action.
Log-record tampering in Graylog's FortiGate syslog parser enables unauthenticated network senders to overwrite or erase critical security-log fields - including srcip, dstip, date, time, and tz - or cause entire log messages to be silently discarded, creating a viable log-evasion primitive. Affected are Graylog Server versions prior to 6.3.12, 7.0.7, and 7.1.2 (all branches), and Graylog Forwarder prior to version 7.3, on any deployment ingesting FortiGate key-value syslog. No public exploit code exists and this is not in CISA KEV, but the attack requires no authentication and minimal crafting skill, making it a realistic threat to security-monitoring integrity in FortiGate-centric environments.
Remote code execution in Fortinet FortiClientWindows affects versions 7.2.0-7.2.11 and 7.4.0-7.4.3, exploitable by any attacker capable of intercepting or forging DNS responses destined for the target host. Maliciously crafted DNS response packets trigger a classic buffer overflow (CWE-120) in the client's DNS parsing logic, allowing arbitrary code execution without requiring any credentials or user interaction. No public exploit or CISA KEV listing has been identified at time of analysis, and the high attack complexity requirement (DNS MITM/poisoning position) meaningfully limits opportunistic exploitation.
Authentication bypass in Fortinet FortiManager and FortiManager Cloud allows unauthenticated remote attackers to circumvent access controls via an alternate path or channel, potentially gaining full administrative control over managed security infrastructure. Affected version ranges span FortiManager 7.2.5 through 7.6.1 and FortiManager Cloud 7.2.5 through 7.6.1, covering multiple active release branches of this centralized network security management platform. No CISA KEV listing or confirmed public exploit has been identified at time of analysis, but the unauthenticated network vector combined with full C/I/A impact and the high-value nature of the target - a platform governing firewall policy across entire enterprise estates - elevates real-world priority significantly beyond the AC:H qualifier alone.
Authentication bypass in Fortinet FortiWeb (versions 7.0.0-7.0.12, 7.2.0-7.2.12, 7.4.0-7.4.11, 7.6.0-7.6.6, and 8.0.0-8.0.2) lets a remote unauthenticated attacker log into the GUI/CLI management interface using an arbitrary, made-up username and password, granting full administrative control of the web application firewall. Tracked as CVE-2026-26035 (EUVD-2026-57193) and rated CVSS 9.8, this is an improper-authentication (CWE-287) flaw reported by Fortinet's own PSIRT (FG-IR-26-158). There is no public exploit identified at time of analysis and it is not on the CISA KEV list, but the trivial exploitability and network exposure make it a high-priority patch.
Stack-based buffer overflow in Fortinet FortiOS, FortiProxy, and FortiPAM allows unauthenticated remote attackers to execute arbitrary code or commands within the WAD (Web Application Daemon) process via crafted sockets - but only on devices where the explicit proxy is simultaneously configured with Kerberos authentication and SOCKS enabled. Exploitation further requires defeating stack canary protection and ASLR, elevating real-world attack complexity well above the raw CVSS base score implies. No public exploit or active exploitation has been confirmed; Fortinet PSIRT published advisory FG-IR-26-161 disclosing the issue.
Improper TLS certificate validation in Fortinet FortiClientEMS (Endpoint Management Server) exposes sensitive information to network-positioned attackers across FortiClientEMS 7.2 (all listed builds up to 7.2.14), 7.4.0–7.4.1, and 7.4.3–7.4.5. Because the client fails to properly verify server certificates (CWE-295), an attacker able to intercept EMS communications can decrypt or observe protected traffic to disclose information. There is no public exploit identified at time of analysis and CISA SSVC scores exploitation as 'none', but Fortinet rates the flaw CVSS 9.8, so patching should be prioritized despite the lack of observed exploitation.
Privilege escalation in Fortinet FortiSIEM Windows Agent 7.4.0 through 7.4.1 stems from an improper restriction of the agent's communication channel (CWE-923), letting an adjacent-network attacker interact with an endpoint that should be limited to trusted parties and thereby gain elevated privileges with full confidentiality, integrity, and availability impact. The flaw was disclosed by Fortinet PSIRT (FG-IR-26-155) and carries a CVSS 7.5 rating; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. Exploitation is gated by high attack complexity, which materially reduces real-world likelihood despite the unauthenticated vector.
Exposure of a scanning VM's VNC service in Fortinet FortiSandbox 5.0.0-5.0.2 and 4.4.3-4.4.8 lets an unauthenticated remote attacker reach the VNC server of the sandbox virtual machines used for malware detonation via ordinary network requests. Because these VMs run and observe live malware samples, unauthorized VNC access can expose sensitive analysis sessions and potentially allow interaction with the detonation environment. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Unauthenticated OS command injection in Fortinet FortiSandbox (on-premise, Cloud, and PaaS variants) allows remote attackers to execute arbitrary operating system commands by sending specifically crafted HTTP requests to the management interface. The flaw carries a CVSS 9.8 rating with network-reachable, no-authentication, no-user-interaction characteristics, and no public exploit identified at time of analysis. Because FortiSandbox is a security-analysis appliance handling untrusted samples, compromise undermines the integrity of malware verdicts and downstream detections.
Critical unauthenticated access control bypass in Fortinet FortiAuthenticator versions 6.5.0-6.5.6, 6.6.0-6.6.8, 8.0.0, and 8.0.2 enables remote code execution without authentication. The CVSS score of 9.8 with AV:N/AC:L/PR:N/UI:N indicates trivial remote exploitation against default configurations. While the vendor advisory (FG-IR-26-128) confirms this vulnerability, the incomplete description placeholder ('<insert attack vector here>') suggests the advisory may contain additional details not yet published in CVE records. No public exploit code or active exploitation confirmed at time of analysis, though the authentication bypass nature and maximum CVSS scores make this a priority patching target for organizations running FortiAuthenticator.
Remote code execution in Fortinet FortiSandbox 4.4.x through 5.0.x (on-premises, Cloud, and PaaS deployments) allows unauthenticated attackers to execute arbitrary code or commands via crafted HTTP requests. This CWE-862 missing authorization flaw affects sandbox analysis appliances across multiple deployment models with CVSS 9.8 (critical) severity. Fortinet has published vendor advisory FG-IR-26-136. No CISA KEV listing or public POC identified at time of analysis, though the trivial attack complexity (AC:L) and network vector without authentication (PR:N) indicate high exploitability if technical details emerge.
Out-of-bounds write in FortiWeb administrative interface enables authenticated remote code execution on web application firewall appliances. Affects FortiWeb 7.4.0-7.4.11, 7.6.0-7.6.6, and 8.0.0-8.0.3. CVSS 7.2 indicates high-privilege authenticated network attack with low complexity. No public exploit identified at time of analysis, though the incomplete advisory description ('<insert attack vector here>') suggests disclosure may be pending or sanitized. Memory corruption class (CWE-787) typically enables arbitrary code execution, confirmed by CVSS impact ratings (High C/I/A). EPSS data not available for risk probability assessment.
Path traversal vulnerability in Fortinet FortiOS, FortiProxy, FortiPAM, and FortiSwitchManager allows authenticated administrators with read-write permissions to write or delete arbitrary files via malicious CLI commands, potentially compromising system integrity and availability across multiple Fortinet product lines. The vulnerability affects FortiOS 6.4 through 7.6.4, FortiProxy 7.0 through 7.6.4, FortiPAM 1.0 through 1.7.0, and FortiSwitchManager 7.0 through 7.2.7. With a CVSS score of 6.0 a
Path traversal in Fortinet FortiSandbox 4.4.0-4.4.8 and 5.0.0-5.0.5 enables remote unauthenticated attackers to achieve full system compromise. With CVSS 9.8 (AV:N/AC:L/PR:N/UI:N), the vulnerability permits network-based exploitation without credentials or user interaction, leading to complete confidentiality, integrity, and availability impact. Despite critical severity, EPSS score of 0.06% (18th percentile) indicates low observed exploitation probability. No active exploitation confirmed (not in CISA KEV). SSVC framework marks it as automatable with total technical impact but no current exploitation. The incomplete CVE description (placeholder text for attack vector) suggests early disclosure; verify completeness with Fortinet advisory FG-IR-26-112.
Remote code execution in Fortinet FortiAnalyzer Cloud and FortiManager Cloud versions 7.6.2 through 7.6.4 allows unauthenticated remote attackers to execute arbitrary code via crafted network requests exploiting a heap-based buffer overflow (CWE-122). Attack complexity is rated high due to ASLR and network segmentation defenses requiring significant exploitation preparation. CVSS score of 8.1 reflects the critical impact despite defensive barriers. No public exploit identified at time of analysis, though the vulnerability's disclosure by Fortinet suggests patch availability through their security advisory FG-IR-26-121.
SQL injection in Fortinet FortiDDoS-F 7.2.1-7.2.2 allows authenticated remote attackers to execute unauthorized code or commands with high impact to confidentiality, integrity, and availability. The vulnerability resides in the web management interface and requires low attack complexity with no user interaction. No public exploit identified at time of analysis, with EPSS data not yet available for this recently disclosed CVE.
Authentication bypass in Fortinet FortiSOAR allows unauthenticated remote attackers to circumvent two-factor authentication (2FA) protections via replay attacks against intercepted authentication tokens. Affects both PaaS and on-premise deployments of FortiSOAR versions 7.5.0-7.5.2 and 7.6.0-7.6.3. Successful exploitation requires network positioning to intercept and decrypt authentication traffic, then replay captured 2FA requests before token expiration (CVSS:3.1/AV:N/AC:H/PR:N/UI:R). EPSS data not available; no public exploit code or CISA KEV listing identified at time of analysis, though the precise attack requirements (traffic interception, decryption, timing) increase complexity beyond simple network access.
Fortinet FortiSOAR transmits sensitive information in cleartext over the network, allowing authenticated remote attackers to disclose confidential data. The vulnerability affects both PaaS and on-premise deployments across versions 7.3 through 7.6.x, with CVSS 6.5 reflecting moderate confidentiality impact requiring low-privilege authentication. No public exploit code or active exploitation has been confirmed at time of analysis.
OS command injection in Fortinet FortiSandbox 4.4.0-4.4.8 and FortiSandbox PaaS versions 21.3-23.4 enables remote unauthenticated attackers to execute arbitrary system commands with complete system compromise. CVSS 9.8 (network, low complexity, no privileges) but EPSS 0.29% (53rd percentile) suggests limited real-world exploitation observed despite maximum severity score.

Crafted CLI commands fed to the newcli daemon on Fortinet FortiOS - and on the related FortiProxy, FortiSwitch, FortiPAM and FortiSASE platforms that share the code base - trigger a double free that crashes the daemon, giving a local, highly privileged authenticated administrator a low-impact denial of service. Exploitation requires an interactive, already-authenticated administrative CLI session, with no remote, unauthenticated or default-configuration path; no public exploit has been identified at time of analysis. At CVSS 2.3 (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L), this is a low-priority, low-real-risk issue despite being a named CVE.
FortiSandbox and FortiSandbox Cloud ship with a hard-coded cryptographic key that is used to validate or sign trusted HTTP requests, allowing an unauthenticated remote attacker who knows that static key to craft requests the appliance treats as legitimate and thereby escalate privileges. Per the assessed vector (CVSS:3.1/AV:N/AC:L/PR:N/UI:N, official score 5.3), no valid credentials or user interaction are required once the embedded key is known, though exploitation is limited to deployments that expose the HTTP/management interface to the attacker's network. Affected versions are FortiSandbox 5.2.0-5.2.1, 5.0.0-5.0.6 and all 4.4 releases, plus the corresponding FortiSandbox Cloud versions; there is no public exploit identified at time of analysis, but the issue is authoritative-moderate severity and should be remediated rather than treated as an emergency.
Sensitive information disclosure in Fortinet FortiAnalyzer, FortiAnalyzer Cloud, and FortiManager allows an authenticated low-privileged user to extract data from the underlying database via SQL injection. Affected versions include FortiAnalyzer 7.6.0-7.6.4, 7.4.0-7.4.7, and all 7.2 versions; FortiAnalyzer Cloud 7.6.2-7.6.4, 7.4.1-7.4.7, and 7.2.1-7.2.11; and FortiManager 7.6.0-7.6.4, 7.4.0-7.4.6, and all 7.2 versions. This is a moderate-priority vulnerability due to the authentication requirement, and no public exploit code has been identified at time of analysis.
Authenticated low-privileged users can exploit an SQL injection flaw in Fortinet FortiAnalyzer and FortiAnalyzer Cloud to execute arbitrary commands on the underlying system. The vulnerability affects FortiAnalyzer 7.6.0-7.6.4, 7.4.0-7.4.7, and all 7.2 versions, as well as FortiAnalyzer Cloud 7.6.2-7.6.4, 7.4.1-7.4.7, and 7.2.1-7.2.11. The CVSS 3.1 score is 8.8 (High) with a vector requiring network access and low privileges; no public exploit code has been identified at time of analysis.
Authenticated SQL injection in Fortinet FortiMail versions 7.6.0 through 7.6.3, 7.4.0 through 7.4.5, and 7.2.0 through 7.2.8 allows an attacker with a low-privilege account to execute unauthorized code or commands via crafted HTTP/HTTPS requests to the management or webmail interface. The vulnerability requires network reachability and a valid session (PR:L) but no user interaction, with low attack complexity. No public exploit has been identified at time of analysis, but the high CVSS score (8.8) and potential for full compromise of confidentiality, integrity, and availability make it a credible priority for operators, especially if the interface is internet-facing.
Persistent denial of management access in Fortinet FortiSandbox stems from an uncaught exception (CWE-248) triggered by crafted HTTP requests sent to the appliance's GUI/CLI management interface; FortiSandbox 5.2.0 through 5.2.1, 5.0.0 through 5.0.6, and all 4.4 versions are affected. Exploitation is not unauthenticated - the CVSS vector (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H) shows a privileged account on the management interface is required, so realistic abuse is confined to insiders or misuse of already-compromised administrative credentials, and the resulting impact is limited to availability (persistent loss of GUI and CLI access) with no data exposure or modification. There is no confirmed active exploitation and no public exploit identified at time of analysis; the issue is a modest-priority availability concern rather than an emergency, with remediation guidance published in Fortinet PSIRT advisory FG-IR-26-176.
A missing authorization check in Fortinet FortiSIEM 7.5.0 lets an attacker with an already-authenticated, high-privilege account send specially crafted HTTP requests to invoke functionality they should not be authorized to reach, potentially resulting in unauthorized code or command execution. Exploitation requires an existing PR:H-level account (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:L, base 3.8), so the realistic threat is a malicious insider or an attacker who has already compromised a privileged FortiSIEM account rather than an unauthenticated outsider; confidentiality is unaffected and only low-level integrity and availability impact is scored. There is no confirmed active exploitation (not in CISA KEV) and no public exploit identified at time of analysis, keeping this a low-priority item, though its command-execution potential warrants prompt patching where privileged-account hygiene is weak.
OS command injection in Fortinet FortiManager (8.0.0 and 7.6.0-7.6.6) and FortiManager Cloud (7.6.2-7.6.6) allows a high-privileged authenticated attacker on an adjacent network to execute arbitrary operating system commands, enabling privilege escalation and potential full compromise of the management appliance. The vulnerability requires an existing administrative account (CVSS PR:H) and network adjacency (AV:A), and no public exploit identified at time of analysis. Despite the high-value nature of the target, these prerequisites substantially narrow realistic risk to post-compromise or malicious insider scenarios, consistent with the moderate-risk assessment.
Authenticated denial of service in Fortinet FortiOS, FortiPAM, and FortiProxy allows a high-privileged network attacker to crash the httpsd daemon by sending specially crafted HTTP requests, exploiting a NULL pointer dereference (CWE-476). The vulnerability spans FortiOS 7.2.x and 7.4.x, FortiProxy 7.2 through 7.6.6, and every FortiPAM release from 1.0.0 through 1.9.0. No active in-the-wild exploitation is confirmed, but the CVSS temporal metric E:P indicates proof-of-concept code exists; Fortinet has released an official fix under advisory FG-IR-26-173.
Improper access control in Fortinet FortiManager and FortiManager Cloud allows authenticated administrators to bypass the workflow session approval process via crafted HTTP or HTTPS requests (CWE-284). Affected versions span FortiManager 6.4.x through 7.6.4 and FortiManager Cloud 6.4.x through 7.6.4 per EUVD intelligence, a broader range than the base CVE description indicates. An admin who should be subject to a change-management or four-eyes approval policy can circumvent that gate, pushing unapproved configuration changes to managed FortiGate devices. No public exploit code or CISA KEV listing is identified at time of analysis.
Denial of service in Fortinet FortiAnalyzer 7.6.3 through 7.6.6 is achievable by a low-privileged remote attacker exploiting a use of uninitialized variable (CWE-457) flaw. A confirmed proof-of-concept exists per the CVSS temporal vector (E:P), and an official remediation is available per the Fortinet PSIRT advisory FG-IR-26-172. The CVE description contains a verbatim placeholder ('<insert attack vector here>') instead of the specific triggering mechanism, reducing technical precision; however, the CVSS vector (AV:N/AC:L/PR:L) confirms network-reachable exploitation requiring only low-privilege credentials. No confirmed active exploitation (CISA KEV) has been identified at time of analysis.
Improper access control (CWE-284) in Fortinet FortiSOAR allows an authenticated low-privilege user to escalate their privileges within the platform via an undisclosed attack vector. Both PaaS and on-premise deployments across FortiSOAR versions 7.3 through 7.6.6 are affected. No public exploit or CISA KEV listing is present at time of analysis; the Fortinet PSIRT advisory FG-IR-26-164 is the sole authoritative source.
Open redirect (CWE-601) in Fortinet FortiSIEM 7.4.1-7.5.1 allows unauthenticated remote attackers to redirect FortiSIEM users to attacker-controlled sites via a crafted URL, enabling phishing or credential-harvesting attacks against security operations personnel. The CVSS temporal score includes E:P (proof of concept exists) and RL:O (official fix available), per Fortiguard advisory FG-IR-26-169. No active exploitation confirmed and no KEV listing; the overall risk is constrained by AC:H and mandatory user interaction, yielding a low base score of 2.8.
Unverified ownership checks in Fortinet FortiClientWindows allow a locally authenticated administrator to perform improper access control operations, resulting in high availability impact and minor integrity modification of the endpoint security client. Affected versions are FortiClientWindows 7.4.0 through 7.4.7 and 7.2.0 through 7.2.15 on Windows endpoints. No public exploit or active exploitation has been identified; the attack surface is substantially constrained by the local-only, high-privilege prerequisite.
Unauthenticated access control bypass in Fortinet FortiWeb - spanning the 7.0 line through 8.0.2 - and multiple FortiOS branches stems from an incomplete list of disallowed inputs (CWE-184), allowing remote attackers to circumvent input-filtering enforcement and achieve unauthorized integrity modifications. The vulnerability extends to FortiOS, implicating shared blocklist logic across Fortinet's platform stack according to EUVD-2026-57192 and CPE data. Publicly available exploit code exists (CVSS temporal E:P), an official fix has been released (RL:O/RC:C), and no active exploitation has been confirmed in the CISA KEV catalog at time of analysis.
Server-side request forgery in Fortinet FortiSIEM across an extensive version range (6.4.x through 7.5.0) permits authenticated high-privileged attackers to force the server to issue unauthorized requests to internal or external resources, enabling potential lateral movement to internal network services and limited information disclosure. The CVSS base score of 3.4 reflects the dominant mitigating factor of mandatory high-privilege authentication (PR:H), confining exploitation to insiders or post-compromise scenarios. The CVSS temporal metric E:P confirms proof-of-concept exploit code exists, though no CISA KEV listing indicates active widespread exploitation at time of analysis.
Denial-of-service risk in Fortinet FortiOS across five major version branches (6.4.x through 7.6.6) stems from unbounded resource allocation (CWE-770), allowing unauthenticated remote attackers to degrade availability of affected network appliances. The CVSS temporal metric E:P confirms proof-of-concept exploit code exists, and an official patch is available per Fortinet PSIRT advisory FG-IR-26-162. No active exploitation is confirmed in CISA KEV at time of analysis, but the broad version coverage and perimeter-facing nature of FortiOS appliances elevate practical risk.
Stored or reflected cross-site scripting in Fortinet FortiSIEM's web interface enables a high-privileged authenticated attacker to inject malicious script tags that execute in the browsers of other users who view the affected page. The vulnerability spans a wide version range from FortiSIEM 6.4 through 7.4.0, affecting all deployments of this enterprise SIEM platform. No active exploitation has been confirmed by CISA KEV, and no public exploit code is identified at time of analysis; the PR:H requirement meaningfully constrains real-world attacker opportunity despite the scope change to the victim's browser context.
Buffer over-read in Fortinet FortiOS and FortiProxy exposes sensitive memory contents to authenticated network attackers across multiple product lines including FortiPAM and FortiSwitchManager. The flaw, rooted in CWE-126 (buffer over-read), allows low-privileged remote users to read beyond allocated buffer boundaries, resulting in partial information disclosure with no integrity or availability impact. No active exploitation confirmed in CISA KEV, but the CVSS temporal vector includes E:P indicating proof-of-concept exploit code exists, and an official fix is available per RL:O.
FortiOS across the 7.2, 7.4, and 7.6 release trains leaks portions of device runtime memory to authenticated remote attackers via a buffer over-read in redirect response handling. Exploitation requires valid credentials but no elevated privileges, and proof-of-concept code exists (CVSS temporal E:P). An official vendor fix is confirmed available (RL:O), though unpatched instances of FortiOS 7.2.x, 7.4.0-7.4.8, and 7.6.0-7.6.2 remain at risk of sensitive memory disclosure - a consequential exposure given that FortiOS processes session tokens, credentials, and cryptographic material at runtime.
Reflected or stored cross-site scripting in Fortinet FortiOS, FortiPAM, and FortiProxy web interfaces allows a remote unauthenticated attacker to execute JavaScript in the browser session of an authenticated administrator via crafted HTTP requests. The CVSS temporal metric E:P confirms publicly available proof-of-concept exploit code exists, and the RL:O metric confirms Fortinet has released an official fix. No active exploitation has been confirmed by CISA KEV at time of analysis, but the combination of a POC and the high-value targets (network security appliances and privileged access management systems) elevates real-world risk beyond what the base CVSS score of 6.1 suggests.
Path traversal (CWE-22) in Fortinet FortiOS, FortiProxy, and FortiPAM enables a highly-privileged, physically-present attacker to execute unauthorized code or commands by escaping restricted directory boundaries. The vendor-supplied CVSS vector (AV:P/PR:H) constrains exploitation to scenarios requiring both physical device access and high-level credentials, making opportunistic or remote mass exploitation implausible. A proof-of-concept exists per the CVSS temporal indicator (E:P), and Fortinet has released an official fix per PSIRT advisory FG-IR-26-151; this vulnerability is not currently listed in the CISA KEV catalog.
HTTP Response Splitting in Fortinet FortiOS and FortiProxy captive portal authentication flows enables a man-in-the-middle attacker to inject arbitrary HTTP headers into intercepted authentication requests. Affected platforms span FortiOS 7.2-7.6.4 and FortiProxy 7.2-7.6.4. The CVSS temporal vector includes E:P, confirming proof-of-concept exploit code exists; however, no active exploitation has been confirmed via CISA KEV. The RL:O temporal indicator confirms an official remediation is available per vendor advisory FG-IR-26-153.
HTTP Response Splitting in Fortinet FortiOS and FortiProxy enables an attacker who holds a valid web filter override token to inject arbitrary HTTP headers into server responses by tricking a user into clicking a crafted link. Affected versions span FortiOS 7.2 through 7.6.4 and FortiProxy 7.2 through 7.6.4. No active exploitation has been confirmed by CISA KEV, though the CVSS temporal vector includes E:P, indicating partial proof-of-concept evidence exists. Real-world impact is constrained by the requirement to possess a valid web filter override token and to achieve user interaction.
Information disclosure in Fortinet FortiAuthenticator (6.5 all versions and 6.6.0–6.6.2) lets a remote unauthenticated attacker read out-of-bounds memory via a specially crafted request, exposing sensitive in-memory data. The CVSS temporal metrics (E:F, RC:C) indicate a functional, confirmed exploit is understood by the vendor, and an official fix is available (RL:O). No CISA KEV listing is present, so this is not confirmed as actively exploited despite the mature exploit signal.
Stack-based buffer overflow in Fortinet FortiOS, FortiPAM, FortiProxy, and FortiSASE enables arbitrary code execution for a privileged authenticated attacker capable of bypassing ASLR and stack canary protections via crafted HTTP requests. The CVSS temporal metric E:P confirms proof-of-concept exploit code exists, and RL:O confirms an official patch has been released by Fortinet (advisory FG-IR-26-148). This vulnerability is not listed in CISA KEV at time of analysis, and the dual prerequisites of privileged access plus memory-protection bypass substantially constrain real-world exploitability despite the critical CIA impact triad.
Fortinet FortiOS and FortiProxy expose an internal debug interface (CWE-1244) that allows authenticated administrators to execute arbitrary Lua scripts through crafted CLI commands, exceeding their intended administrative scope. The vulnerability spans broad version ranges of both products, including FortiOS 6.4 through 7.6.2 and FortiProxy 7.0 through 7.6.3. While exploitation requires existing high-privilege (admin) access - limiting opportunistic attack surface - the CVSS temporal vector (E:P) confirms a proof-of-concept exploit exists, and the official fix is available (RL:O). No public exploit identified at time of analysis beyond the proof-of-concept, and this vulnerability is not listed in CISA KEV.
Improper access control in Fortinet FortiPortal versions 7.0.x (all), 7.2.0-7.2.8, and 7.4.0-7.4.7 enables an authenticated low-privilege attacker to bypass authorization controls and gain unauthorized read access to sensitive data. The CVSS vector (AV:N/AC:L/PR:L/UI:N/C:H) indicates low-complexity network exploitation by any authenticated user, resulting in high confidentiality impact with no integrity or availability loss. No public exploit identified at time of analysis based on CISA KEV, though publicly available exploit code exists per the CVSS temporal E:P metric, and Fortinet has issued an official fix.
OS command injection in Fortinet FortiAP and FortiAP-W2 access points allows authenticated administrators to execute arbitrary code or commands via specially crafted CLI commands. Affected versions span FortiAP 6.4 through 7.6.2 and FortiAP-W2 7.0 through 7.4.4. The vulnerability requires high-privilege administrative access and does not require user interaction, making it exploitable by rogue administrators or accounts with compromised credentials. No public exploit code or active exploitation has been identified at time of analysis.
OS command injection in Fortinet FortiAP, FortiAP-U, and FortiAP-W2 allows authenticated privileged attackers to execute arbitrary code via maliciously crafted CLI requests. Affected versions span FortiAP 6.4 through 7.6.2, FortiAP-U 6.2 through 7.0.5, and FortiAP-W2 7.0 through 7.4.4. The vulnerability requires high-privilege administrative access and local CLI interaction, limiting exposure to trusted insider threats or compromised management interfaces. CVSS 6.1 reflects the high impact (code execution with full system privileges) constrained by authentication and local access requirements.
Denial-of-service attacks against Fortinet FortiAnalyzer and FortiManager 6.4 through 7.6.4 allow authenticated attackers to trigger system hangs via specially crafted HTTP requests that exploit a use of potentially dangerous function vulnerability (CWE-676). The crash occurs only when internal lock alignment conditions are met, making exploitation dependent on timing and system state rather than attacker control. CVSS 5.2 reflects medium severity with high attack complexity and low availability impact; active exploitation is not confirmed.
