Authentication Bypass
Monthly
Two-factor authentication bypass in Grav Login Plugin prior to 3.8.11 allows an attacker who possesses a victim's password to completely circumvent TOTP enforcement. By invoking the taskRegenerate2FASecret() endpoint during the pending login window - when the session exists but is not yet authorized - the attacker overwrites the victim's 2FA secret, reads the replacement from the server response, computes a valid code, and completes authentication without the victim's physical device. No public exploit has been identified at time of analysis and the vulnerability is not in CISA KEV, but the attack primitive is explicitly confirmed by vendor advisory GHSA-7mgc-c7pq-3rr3 and the commit diff.
Privilege escalation in Grav API Plugin (all versions before 1.0.6) allows any authenticated user holding the api.users.write permission to mint API keys bound to super-administrator accounts, bypass key scope enforcement, and gain full persistent super-admin access - including the ability to rotate or disable two-factor authentication on targeted accounts. Three endpoints in UsersController - createApiKey(), generate2fa(), and disable2fa() - omitted the accessGrantsSuper() target authorization check that all sibling user mutation endpoints correctly enforced, creating an unguarded escalation path. No active exploitation has been confirmed (not in CISA KEV), and no public exploit code has been identified at time of analysis, though the fix commit is publicly visible and the attack path is structurally a single authenticated API call.
Privilege escalation in Dell Command Update (DCU) versions prior to 5.7.1 allows a local low-privileged attacker to gain elevated system access by exploiting missing authorization checks. The vulnerability carries a CVSS 3.1 score of 8.8 with a scope change (S:C), indicating the privilege escalation extends beyond the DCU process itself - likely to OS-level or other system components. No public exploit or CISA KEV listing has been identified at time of analysis, but the low attack complexity (AC:L) and absence of required user interaction make this straightforward to exploit for any user with a local account.
Unauthenticated remote access to NFS-exported filesystems is possible in IBM AIX 7.2 and 7.3 and IBM PowerVM VIOS 4.1 due to improper authentication (CWE-287). The CVSS vector AV:N/AC:L/PR:N/UI:N confirms that unauthenticated remote attackers on the network can exploit this with low complexity and no user interaction, gaining high-confidence read access and limited write access to exported filesystem data. No public exploit has been identified at time of analysis, and IBM has released a patch via advisory 7283858.
Remote privilege escalation to root in IBM AIX 7.2 and 7.3 and IBM PowerVM VIOS 4.1 stems from an improper authentication weakness (CWE-287) that lets an unauthenticated network attacker bypass identity checks and obtain root-level control. The CVSS 9.8 rating reflects a network-reachable, low-complexity flaw requiring no privileges or user interaction, with full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the severity and unauthenticated network vector make it a high-priority patching target for IBM Power estates.
Missing Authorization in Dell Command Update (DCU) versions prior to 5.7.1 permits a low-privileged local user to invoke protected application functions without adequate authorization checks, yielding full confidentiality, integrity, and availability impact on the vulnerable system. Rooted in CWE-862, the flaw bypasses expected access controls within the DCU client utility - a driver and firmware management tool deployed across Dell client hardware fleets. No public exploit code or confirmed active exploitation has been identified at time of analysis.
Missing authorization in MyBooks (Talebook) 3.41.2 and earlier allows any authenticated low-privilege user - including holders of unactivated accounts - to overwrite server-side configuration through the POST /api/admin/settings endpoint, exposing SMTP credentials, OAuth client secrets, storage paths, and security feature flags to unauthorized modification. Two compounding flaws are present: the AdminSettings.post handler in webserver/handlers/admin.py applies only the authentication decorator without the admin_user check enforced by its GET counterpart, and process_auth_header in webserver/handlers/base.py accepts sessions for registered-but-unactivated accounts by not verifying the user.active flag. No active exploitation has been confirmed (not in CISA KEV), but the fix is available in version 3.42.0.
Improper TLS certificate validation in the NIM (Network Installation Management) subsystem of IBM AIX 7.2, 7.3, and IBM PowerVM VIOS 4.1 enables remote attackers to gain unauthorized access to AIX systems by exploiting the failure to verify certificate authenticity during NIM communications. The CVSS 8.1 High score reflects high confidentiality and integrity impact across a network-exploitable path with low complexity and no user interaction required. No public exploit identified at time of analysis, but the authentication bypass classification of this flaw makes it a meaningful privilege escalation and lateral movement risk in IBM Power environments.
Sensitive-key exposure in IBM AIX 7.2/7.3 and PowerVM VIOS 4.1 Network Installation Management (NIM) leaks intermediate certificate authority (CA) private keys inside a publicly downloadable update file, letting remote attackers forge trusted certificates and bypass security restrictions. Rated CVSS 9.1, the flaw impacts confidentiality and integrity (C:H/I:H) but not availability, and IBM has released a fix. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the ease of obtaining a live CA key makes this a high-priority credential-hygiene issue.
Authentication bypass in the Cudy WR3000 2.0 router (firmware before 2.5.24) lets unauthenticated remote attackers forge valid JWT tokens by reusing a hard-coded HMAC signing secret embedded in the firmware image, granting illegitimate access to the device's Mosquitto MQTT broker and mesh-networking control interface. Because the secret is static across all units of this model, any attacker who obtains one firmware image can authenticate against every deployed device. There is no public exploit identified at time of analysis, but the flaw is trivially exploitable once the secret is extracted, and the network-reachable, no-privilege CVSS 4.0 score of 9.3 (VC:H/VI:H) reflects full read/write access to mesh control.
Anonymous read/write/federation access to Stigmem nodes (versions before 0.9.0a2) is possible when operators disable authentication and bind the node to a non-loopback address, effectively bypassing authorization for the anonymous identity. Reported by VulnCheck and disclosed via GHSA-fp6w-8wpg-74g5, it affects the eidetic-labs stigmem-node package (pip). No public exploit identified at time of analysis, and no EPSS or CISA KEV signal is available; exploitation is gated on a deliberate operator misconfiguration rather than a default-config weakness.
Cross-tenant broken object level authorization (BOLA) in stigmem-node's decay sweep endpoint allows any authenticated write-credentialed tenant to destroy or enumerate facts belonging to all other tenants. Specifically, POST /v1/decay/sweep with ttl_seconds=0 expires every tenant's facts globally due to missing tenant_id predicates in the candidate-selection queries. This vulnerability exclusively affects multi-tenant deployments running the opt-in stigmem-plugin-multi-tenant; no public exploit or CISA KEV listing exists at time of analysis, but the integrity and availability impact against multi-tenant operators is critical.
Cross-tenant broken object level authorization (BOLA) in stigmem-node exposes quarantined facts across tenant boundaries on multi-tenant deployments. A tenant administrator holding only a standard tenant write capability can list, read, and admit or reject quarantined facts belonging to any other tenant on the same node via the /v1/quarantine endpoints - bypassing isolation enforced by the stigmem-plugin-multi-tenant plugin. No public exploit identified at time of analysis; no CISA KEV listing. Default single-tenant deployments are entirely unaffected regardless of version.
Cross-tenant broken object level authorization in stigmem-node before 0.9.0a12 allows an authenticated tenant in a multi-tenant deployment to corrupt RTBF tombstone records and trigger tenant-blind fact suppression. The root cause is twofold: the issue_tombstone function hardcoded the tenant to 'default' instead of reading it from the caller's identity, and the tombstone read-suppression path lacked a tenant_id predicate, causing deletion records to be misattributed and tombstone filtering to operate across all tenants indiscriminately. The impact is limited to deployments running the opt-in stigmem-plugin-multi-tenant; a vendor-released patch exists at 0.9.0a12, and no public exploit has been identified at time of analysis.
Function library integrity in ArcadeDB 26.7.3 and earlier can be silently tampered by any authenticated low-privilege database user because the UPDATE_SCHEMA permission gate is bypassed when a DEFINE FUNCTION statement targets an already-existing library rather than creating a new one. Attackers holding only basic database credentials can overwrite or inject SQL or Cypher function logic authored by administrators, poisoning business logic, data transformations, or access-control routines that depend on those functions. No active exploitation is confirmed (no CISA KEV listing), but the low attack complexity and network reachability (CVSS 4.0 AV:N/AC:L/PR:L) make this a genuine priority for any multi-user ArcadeDB deployment.
Principal-type confusion in Vikunja through 2.4.0 allows an attacker holding a valid link-share JWT to impersonate arbitrary user accounts by exploiting numeric ID collisions between LinkSharing principals and user records. Three permission-check code paths lack type guards, causing the application to treat a LinkSharing principal whose id equals N as the user with users.id == N. With a crafted link-share token, an attacker can remove victims from teams, enumerate and delete bot user accounts, or read team membership rosters. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
Two-factor authentication bypass in phpMyFAQ before 4.1.7 lets an attacker who already knows a valid password defeat the TOTP second factor through unbounded brute force. Because the five-attempt failure counter is stored per session and reset on every successful password re-authentication (CWE-307), an attacker can loop - grab a fresh session cookie, re-enter the known password, and get five more guesses - until the 6-digit TOTP is guessed, yielding full account takeover. Reported by VulnCheck with no public exploit identified at time of analysis and not listed in CISA KEV.
LDAP authentication bypass in phpMyFAQ 3.1.0-4.1.6 allows a blocked local account to be silently reactivated by authenticating via LDAP, letting previously suspended users regain full application access. The AuthLdap::create() method calls User::setStatus('active') unconditionally after any successful LDAP bind, overwriting an administratively set 'blocked' status in the database without logging the state change. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in CISA KEV; the vendor-confirmed fixed release is 4.1.7.
Two-factor authentication bypass in phpMyFAQ before 4.1.7 allows any attacker holding valid first-factor credentials to obtain a remember-me cookie prior to 2FA challenge completion, then replay that cookie to achieve full authenticated access while entirely circumventing the second-factor control. Affected deployments relying on 2FA as their primary defense-in-depth layer against credential compromise are effectively left with single-factor authentication. No public exploit code or CISA KEV listing has been identified at time of analysis, though the bypass logic is straightforward and the vulnerability is trivially reproducible given valid credentials.
Unauthenticated broken access control in the Outranking Plugin Options WordPress plugin (versions 1.1.3 and below) allows remote unauthenticated attackers to modify plugin options, resulting in high integrity impact. The root cause is CWE-862 (Missing Authorization), meaning the plugin fails to verify whether the requesting user has permission before processing option-change requests. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog, though the CVSS:3.1 vector of AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N reflects a low-barrier, fully network-exploitable condition.
Broken access control in the Stitch Express WordPress plugin (versions <= 1.9.0) allows unauthenticated network attackers to perform privileged operations by bypassing missing authorization checks (CWE-862). The CVSS vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N confirms zero-friction remote exploitation with high integrity impact, meaning unauthorized data modification or administrative action is achievable without credentials or user interaction. No public exploit code or CISA KEV listing has been identified at time of analysis; the vulnerability was disclosed by Patchstack.
Authentication bypass in the SAML Single Sign On WordPress plugin (versions 4.8.85 through below 5.4.7) enables unauthenticated network attackers to inject an arbitrary certificate into the site's SAML trust store by exploiting the plugin's failure to verify incoming SAML response signatures before persisting embedded certificates. Once stored, that attacker-controlled certificate can be promoted to the site's active trusted signing authority via a single administrator UI click, after which the attacker can forge SAML assertions and authenticate as any WordPress user, including site administrators. No public exploit code or CISA KEV listing has been identified at time of analysis; EPSS is very low at 0.11% (1st percentile), reflecting limited observed exploitation.
Account takeover in the TrueBooker WordPress plugin (all versions before 1.2.7) lets remote unauthenticated attackers change the email address of any registered user - including administrators - through AJAX actions that lack authorisation checks, then hijack the account via WordPress's standard password-reset flow. The flaw carries a CVSS 9.8 and is fixed in 1.2.7; there is no public exploit identified at time of analysis, and EPSS remains low (0.15%, 4th percentile), reflecting limited observed weaponisation despite the critical rating.
Authentication bypass in the TabaPay Gateway WordPress plugin (versions through 1.4.0) lets unauthenticated remote attackers log in as any registered user - including administrators - by abusing the payment callback handler. Because the plugin establishes a session for the account tied to a referenced order without validating the payment callback's authenticity, an attacker who can reach the callback endpoint can impersonate arbitrary accounts. No public exploit identified at time of analysis, and EPSS is low (0.15%, 4th percentile), but the flaw is trivially exploitable and CISA's SSVC framework rates it fully automatable with total technical impact.
Unauthenticated account lockout in the User Verification by PickPlugins WordPress plugin (through version 2.0.47) enables remote attackers to reset the email-verification status of any WordPress account - including administrators - by exploiting two authorization failures simultaneously: the resend-verification endpoint neither validates that the requestor is authorized to act on the specified user ID, nor binds the protective token to the targeted user. This effectively provides a remote, zero-privilege mechanism to lock any site account out of access. No public exploit code exists at the time of analysis, though SSVC classifies the attack as automatable, meaning bulk account disruption campaigns are technically feasible.
Improper access control in the Eventin WordPress plugin before 4.1.21 allows any authenticated user holding contributor-level access or higher to permanently delete arbitrary user accounts on the affected WordPress installation. The plugin's account deletion functionality omits both ownership verification and WordPress capability checks, meaning a low-privilege contributor can target and remove administrator accounts. No active exploitation has been confirmed by CISA KEV, and no public exploit code has been identified at time of analysis; however, the low technical barrier makes this a meaningful privilege-abuse risk on multi-author WordPress sites.
Unauthorized event takeover in the Eventin WordPress plugin (all versions before 4.1.21) allows any authenticated contributor-level user to modify, delete, or reassign events owned by other users - including site administrators. The flaw is a classic Insecure Direct Object Reference (IDOR) rooted in CWE-639: the plugin processes event operations using a user-supplied event identifier without verifying the requesting user actually owns or has authorization over the targeted record. No active exploitation has been confirmed (not in CISA KEV) and no public proof-of-concept code was identified at time of analysis, but the low privilege bar and mechanically simple IDOR exploitation pattern elevate real-world risk for any multi-author WordPress deployment.
Incorrect authorization in acmailer enables any authenticated low-privilege user to create a sub-account bearing full administrative privileges, effectively allowing unauthorized privilege escalation within the application. The flaw (CWE-863) bypasses the intended privilege boundary during sub-account creation, granting attackers administrator-level control over the mailing list system without requiring any elevated starting permissions. No public exploit code or CISA KEV listing has been identified at time of analysis, though the low attack complexity and high impact across confidentiality, integrity, and availability make this a serious risk where untrusted or semi-trusted users have accounts.
Unauthorized access to user chat data in Bottinelli Informatica Vedo Suite 1.2.5 is possible via an Insecure Direct Object Reference (IDOR) flaw in the api_vedo/chat REST endpoint, where the utente_chat parameter is not validated against the requester's session or authorization context. The 'Authentication Bypass' tag alongside a PR:N CVSS vector indicates the endpoint may be reachable without any valid credentials, making this a high-confidence confidentiality breach for any network-accessible deployment. No public exploit code has been confirmed in automated exploit frameworks, and the EPSS score of 0.24% (16th percentile) indicates limited observed exploitation at time of analysis, consistent with a low-prevalence niche product.
SSO account takeover in 4gaBoards prior to version 3.3.9 allows any authenticated user to overwrite backend-managed OAuth identity fields on their own account via the PATCH /api/users/:id endpoint, redirecting a victim's SSO login to the attacker's account. The root cause is a mass-assignment flaw in server/api/controllers/users/update.js that incorrectly exposed SSO provider identifiers - including Google, GitHub, Microsoft, and OIDC subject IDs and emails - to user-controlled input. No public exploit is identified at time of analysis, but the attack mechanism is mechanically straightforward given the confirmed source code diff, and exploitation fully transfers the victim's project and board access to the attacker.
Pre-account takeover in 4gaBoards before 3.3.8 allows a remote unauthenticated attacker to seize a victim's account before the victim ever logs in, by exploiting the SSO identity-linking logic. An attacker registers an unverified local account using the victim's email address; when the victim subsequently logs in via Google, GitHub, Microsoft, or OIDC SSO, the server locates the attacker's pre-registered account by email and links the verified SSO identity to it without confirming local account ownership, granting the attacker persistent password access to the now-SSO-linked account and all associated projects and data. No public exploit code or CISA KEV listing has been identified at time of analysis; the CVSS 8.8 score reflects the low attack complexity and high impact once victim interaction occurs.
Improper authorization in Atlassian Bamboo Data Center across six affected release lines (10.0.x through 12.1.x) enables authenticated low-privilege users to bypass access controls and reach restricted resources or functionality, with Atlassian tagging the flaw as carrying arbitrary code execution risk. The vulnerability was discovered through Atlassian's own penetration testing program and affects Data Center deployments only - not Bamboo Cloud. No public exploit code or CISA KEV listing exists at time of analysis, but the high confidentiality and integrity impact ratings (VC:H/VI:H in CVSS 4.0) and the RCE tag make this a credible escalation risk in any environment where untrusted or lightly-privileged users hold Bamboo accounts.
Broken authentication in Atlassian Crowd Data Center 7.2.1 permits a remote, unauthenticated attacker to perform actions on behalf of any other user, effectively bypassing the platform's identity and session controls. The flaw was introduced specifically in version 7.2.1, discovered through Atlassian's Penetration Testing program, and carries a CVSS 4.0 score of 8.8 with scope-changing impact that cascades to all downstream SSO-federated applications. No active exploitation (CISA KEV) and no public exploit code have been identified at time of analysis, though the cross-system propagation potential demands urgent patching.
Authentication bypass in TP-Link Tapo C200 v5 IP cameras running firmware below V5_1.4.6 Build 260709 Rel.27675n allows unauthenticated adjacent-network attackers to manipulate challenge parameters during the login handshake, circumventing the authentication verification module and obtaining valid administrative session tokens. With those tokens, an attacker can execute privileged management operations - including reconfiguring the camera, accessing live or recorded footage, and deliberately disrupting device services to cause a denial-of-service condition. No public exploit identified at time of analysis, and the adjacent-network requirement (AV:A) constrains exposure to attackers already present on the same LAN or Wi-Fi segment.
Unauthenticated remote exploitation of Oracle Helidon 3.2.20's Imperative Web Server component enables attackers to perform unauthorized creation, deletion, or modification of critical data via HTTP with no prerequisites. The vulnerability carries a scope change (S:C in CVSS), meaning successful exploitation can cascade to impact additional products or systems beyond Helidon itself. Tagged as an authentication bypass, this is classified by Oracle as easily exploitable with no public exploit identified at time of analysis.
Unauthorized data access in Oracle Helidon 4.5.0 exposes all data reachable through the Imperative Web Server component to unauthenticated remote attackers over HTTP. Tagged as an authentication bypass, the flaw allows complete confidentiality compromise - an attacker can read critical or all accessible application data without supplying credentials. No public exploit has been identified at time of analysis, but the CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms the attack is trivially executable from any network position.
Remote denial-of-service and partial data exposure in Oracle Helidon 4.5.0 allows unauthenticated network attackers via HTTP/2 to cause a complete hang or crash of the Helidon Imperative Web Server, alongside unauthorized read access to a subset of accessible data. The vulnerability is classified as easily exploitable with no authentication, user interaction, or special configuration required. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis, but the low attack complexity and network-accessible vector make this a realistic denial-of-service threat against any exposed Helidon 4.5.0 deployment.
Remote denial-of-service in Oracle Helidon 4.5.1's Imperative Web Server component allows unauthenticated network attackers to hang or repeatedly crash the service via HTTP. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) confirms trivial, zero-prerequisite exploitation against any reachable instance. No public exploit code or CISA KEV listing has been identified at time of analysis, though the low attack complexity makes this a credible threat to internet-facing deployments.

The CVSS 3.1 score of 7.5 reflects the low attack complexity and complete availability impact, with no authentication or user interaction required. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Unauthenticated remote exploitation of Oracle Helidon 4.5.3's Imperative Web Server component allows attackers with HTTP network access to perform unauthorized read, write, and partial denial-of-service operations against data accessible to the service. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) confirms this is easily exploitable with no prerequisites, though impacts are bounded to partial CIA effects within the unchanged scope of the Helidon instance. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
Unauthenticated remote exploitation of Oracle Helidon 4.5.3's Imperative Web Server component allows network attackers over HTTP to achieve partial confidentiality disclosure, data manipulation, and denial of service - with a confirmed scope change indicating the impact can extend to components beyond Helidon's own security boundary. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:C) places this among the most easily reachable vulnerability classes: no credentials, no user interaction, and no elevated complexity required. Disclosed in Oracle's August 2026 Critical Security Patch Update, no public exploit code or CISA KEV listing has been identified at time of analysis.

No public exploit code has been identified at time of analysis, and Oracle disclosed this through its August 2026 Critical Patch Update.
Unauthenticated remote exploitation of Oracle Helidon 4.5.3's Imperative Web Server component allows attackers to bypass authentication controls via HTTP, resulting in unauthorized read access to a subset of application data and the ability to insert, update, or delete accessible records. The CVSS scope change (S:C) indicates successful exploitation can affect additional systems beyond the Helidon instance itself - a compounding factor in microservices topologies where Helidon acts as a gateway or intermediary. No public exploit code and no CISA KEV listing have been identified at time of analysis, though the unauthenticated, low-complexity attack path makes this credible against any internet-exposed deployment.
Denial-of-service in Oracle Helidon 3.2.20 (Imperative Web Server component) allows unauthenticated remote attackers to repeatedly crash or indefinitely hang the server via crafted HTTP requests. The vulnerability is rated CVSS 7.5 with no authentication, no user interaction, and low attack complexity, making it trivially exploitable at scale against any exposed instance.

No public exploit code has been identified at time of analysis, and the vulnerability is addressed in Oracle's Critical Security Patch Update for August 2026.
Unauthorized data disclosure in Oracle Helidon 3.2.18's Imperative Web Server component exposes all Helidon-accessible data to unauthenticated remote attackers via HTTP. Tagged as an Authentication Bypass, the flaw enables any network-positioned attacker to read critical or complete Helidon-managed data without credentials or user interaction, as confirmed by the AV:N/AC:L/PR:N/UI:N CVSS 3.1 vector. No public exploit has been identified at time of analysis, but the absence of any exploitation prerequisites significantly elevates real-world urgency for any internet-facing or internally networked Helidon 3.2.18 deployment.
Unauthorized data access and partial data manipulation in Oracle Helidon 3.2.18's Imperative Web Server component allows a low-privileged attacker with HTTP network access to gain complete read access to all Helidon-accessible data and limited write capability. The vulnerability carries a scope change, meaning successful exploitation can cascade to impact additional products beyond Helidon itself within the Oracle Fusion Middleware ecosystem. No public exploit code has been identified at time of analysis, but the low attack complexity and absence of required user interaction make this a realistic target for authenticated internal or service-account-level adversaries.
Remote unauthenticated denial-of-service in Oracle Helidon 1.4.20 allows network-accessible attackers to crash or indefinitely hang the Imperative Web Server via HTTP, with no authentication or user interaction required. The CVSS 3.1 score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) confirms trivially low exploitation complexity against exposed instances. No public exploit code or CISA KEV listing exists at time of analysis, but the combination of network accessibility and zero prerequisites makes this a realistic operational risk for any deployment of the affected version.
Remote takeover in Oracle Helidon 4.5.0 lets an unauthenticated attacker fully compromise the framework's Imperative Web Server component over HTTP. The flaw carries a CVSS 3.1 base score of 9.8 with high confidentiality, integrity, and availability impact and no authentication or user interaction required, per Oracle's August 2026 Critical Patch Update. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, but the trivial exploitability rating warrants urgent patching.
Full compromise of Oracle Hyperion Financial Management version 11.2.25.0.000 is achievable by low-privileged network attackers via HTTP, targeting the Security component to gain complete control over confidentiality, integrity, and availability. The CVSS 3.1 score of 8.8 reflects the combination of network accessibility, low attack complexity, and no user interaction required beyond a valid low-privilege account. No public exploit code or CISA KEV listing has been identified at time of analysis, though the severity of the stated outcome - full system takeover - warrants immediate patch application.
Critical data exposure and integrity compromise in Oracle Communications Unified Inventory Management (UIM) allows unauthenticated network attackers to read or tamper with all UIM-accessible data via a vulnerable third-party component over HTTP. Affected versions span 7.5.0 through 8.0.1, covering a wide active deployment range. The vulnerability carries an Authentication Bypass tag and is rated CVSS 7.4 with High Complexity, meaning exploitation is non-trivial but requires no credentials - no public exploit or CISA KEV listing has been identified at time of analysis.
Unauthorized data disclosure in Oracle Communications Unified Inventory Management (versions 7.5.0-7.5.1, 7.6.0-7.8.0, and 8.0.1) exposes critical inventory data to unauthenticated remote attackers over HTTP. The flaw resides in the Security Component and is tagged as an Authentication Bypass, meaning the platform's access controls can be circumvented without any credentials or user interaction, granting complete read access to all data the application can reach. No public exploit has been identified at time of analysis, and the vulnerability is not currently listed in CISA KEV, but the trivially low exploitation complexity makes rapid patching essential.
Oracle VM VirtualBox 7.2.14 Core component exposes a scope-changing integrity vulnerability that allows a local unauthenticated attacker - with logon access to the infrastructure hosting the hypervisor - to critically compromise VirtualBox data when a legitimate third party interacts with the product. The attack vector is local and requires human interaction, but the CVSS scope change (S:C) indicates that a successful exploit can break VM containment and significantly impact the host system or co-resident components beyond VirtualBox itself. No public exploit is identified at time of analysis, and the vulnerability is addressed via Oracle's August 2026 Critical Security Patch Update.
Local privilege escalation and denial-of-service in Oracle VM VirtualBox 7.2.14 allows a high-privileged attacker with local infrastructure access to crash the hypervisor, partially read or modify VM-accessible data, and - critically - extend impact beyond the vulnerable instance to additional products via a confirmed scope change. The CVSS 3.1 vector (AV:L/PR:H/S:C/A:H) indicates this is not a remote threat but a post-compromise or insider-level concern targeting the virtualization layer. No public exploit code or active exploitation has been identified at time of analysis, and Oracle disclosed this through its Critical Patch Update for August 2026.
Local privilege escalation with scope change in Oracle VM VirtualBox 7.2.14 allows a high-privileged local attacker to crash the hypervisor repeatedly, modify limited guest data, and read a subset of accessible data - with impacts that extend beyond the VirtualBox process to additional co-hosted products. No public exploit code has been identified at time of analysis, and this vulnerability is not currently listed in the CISA KEV catalog. The scope change (S:C in CVSS) is the critical differentiator, indicating that a compromised VirtualBox instance can affect the host OS or sibling VMs, raising the actual blast radius above what the per-component impact ratings suggest.
Two-factor authentication bypass in Grav Login Plugin prior to 3.8.11 allows an attacker who possesses a victim's password to completely circumvent TOTP enforcement. By invoking the taskRegenerate2FASecret() endpoint during the pending login window - when the session exists but is not yet authorized - the attacker overwrites the victim's 2FA secret, reads the replacement from the server response, computes a valid code, and completes authentication without the victim's physical device. No public exploit has been identified at time of analysis and the vulnerability is not in CISA KEV, but the attack primitive is explicitly confirmed by vendor advisory GHSA-7mgc-c7pq-3rr3 and the commit diff.
Privilege escalation in Grav API Plugin (all versions before 1.0.6) allows any authenticated user holding the api.users.write permission to mint API keys bound to super-administrator accounts, bypass key scope enforcement, and gain full persistent super-admin access - including the ability to rotate or disable two-factor authentication on targeted accounts. Three endpoints in UsersController - createApiKey(), generate2fa(), and disable2fa() - omitted the accessGrantsSuper() target authorization check that all sibling user mutation endpoints correctly enforced, creating an unguarded escalation path. No active exploitation has been confirmed (not in CISA KEV), and no public exploit code has been identified at time of analysis, though the fix commit is publicly visible and the attack path is structurally a single authenticated API call.
Privilege escalation in Dell Command Update (DCU) versions prior to 5.7.1 allows a local low-privileged attacker to gain elevated system access by exploiting missing authorization checks. The vulnerability carries a CVSS 3.1 score of 8.8 with a scope change (S:C), indicating the privilege escalation extends beyond the DCU process itself - likely to OS-level or other system components. No public exploit or CISA KEV listing has been identified at time of analysis, but the low attack complexity (AC:L) and absence of required user interaction make this straightforward to exploit for any user with a local account.
Unauthenticated remote access to NFS-exported filesystems is possible in IBM AIX 7.2 and 7.3 and IBM PowerVM VIOS 4.1 due to improper authentication (CWE-287). The CVSS vector AV:N/AC:L/PR:N/UI:N confirms that unauthenticated remote attackers on the network can exploit this with low complexity and no user interaction, gaining high-confidence read access and limited write access to exported filesystem data. No public exploit has been identified at time of analysis, and IBM has released a patch via advisory 7283858.
Remote privilege escalation to root in IBM AIX 7.2 and 7.3 and IBM PowerVM VIOS 4.1 stems from an improper authentication weakness (CWE-287) that lets an unauthenticated network attacker bypass identity checks and obtain root-level control. The CVSS 9.8 rating reflects a network-reachable, low-complexity flaw requiring no privileges or user interaction, with full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the severity and unauthenticated network vector make it a high-priority patching target for IBM Power estates.
Missing Authorization in Dell Command Update (DCU) versions prior to 5.7.1 permits a low-privileged local user to invoke protected application functions without adequate authorization checks, yielding full confidentiality, integrity, and availability impact on the vulnerable system. Rooted in CWE-862, the flaw bypasses expected access controls within the DCU client utility - a driver and firmware management tool deployed across Dell client hardware fleets. No public exploit code or confirmed active exploitation has been identified at time of analysis.
Missing authorization in MyBooks (Talebook) 3.41.2 and earlier allows any authenticated low-privilege user - including holders of unactivated accounts - to overwrite server-side configuration through the POST /api/admin/settings endpoint, exposing SMTP credentials, OAuth client secrets, storage paths, and security feature flags to unauthorized modification. Two compounding flaws are present: the AdminSettings.post handler in webserver/handlers/admin.py applies only the authentication decorator without the admin_user check enforced by its GET counterpart, and process_auth_header in webserver/handlers/base.py accepts sessions for registered-but-unactivated accounts by not verifying the user.active flag. No active exploitation has been confirmed (not in CISA KEV), but the fix is available in version 3.42.0.
Improper TLS certificate validation in the NIM (Network Installation Management) subsystem of IBM AIX 7.2, 7.3, and IBM PowerVM VIOS 4.1 enables remote attackers to gain unauthorized access to AIX systems by exploiting the failure to verify certificate authenticity during NIM communications. The CVSS 8.1 High score reflects high confidentiality and integrity impact across a network-exploitable path with low complexity and no user interaction required. No public exploit identified at time of analysis, but the authentication bypass classification of this flaw makes it a meaningful privilege escalation and lateral movement risk in IBM Power environments.
Sensitive-key exposure in IBM AIX 7.2/7.3 and PowerVM VIOS 4.1 Network Installation Management (NIM) leaks intermediate certificate authority (CA) private keys inside a publicly downloadable update file, letting remote attackers forge trusted certificates and bypass security restrictions. Rated CVSS 9.1, the flaw impacts confidentiality and integrity (C:H/I:H) but not availability, and IBM has released a fix. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the ease of obtaining a live CA key makes this a high-priority credential-hygiene issue.
Authentication bypass in the Cudy WR3000 2.0 router (firmware before 2.5.24) lets unauthenticated remote attackers forge valid JWT tokens by reusing a hard-coded HMAC signing secret embedded in the firmware image, granting illegitimate access to the device's Mosquitto MQTT broker and mesh-networking control interface. Because the secret is static across all units of this model, any attacker who obtains one firmware image can authenticate against every deployed device. There is no public exploit identified at time of analysis, but the flaw is trivially exploitable once the secret is extracted, and the network-reachable, no-privilege CVSS 4.0 score of 9.3 (VC:H/VI:H) reflects full read/write access to mesh control.
Anonymous read/write/federation access to Stigmem nodes (versions before 0.9.0a2) is possible when operators disable authentication and bind the node to a non-loopback address, effectively bypassing authorization for the anonymous identity. Reported by VulnCheck and disclosed via GHSA-fp6w-8wpg-74g5, it affects the eidetic-labs stigmem-node package (pip). No public exploit identified at time of analysis, and no EPSS or CISA KEV signal is available; exploitation is gated on a deliberate operator misconfiguration rather than a default-config weakness.
Cross-tenant broken object level authorization (BOLA) in stigmem-node's decay sweep endpoint allows any authenticated write-credentialed tenant to destroy or enumerate facts belonging to all other tenants. Specifically, POST /v1/decay/sweep with ttl_seconds=0 expires every tenant's facts globally due to missing tenant_id predicates in the candidate-selection queries. This vulnerability exclusively affects multi-tenant deployments running the opt-in stigmem-plugin-multi-tenant; no public exploit or CISA KEV listing exists at time of analysis, but the integrity and availability impact against multi-tenant operators is critical.
Cross-tenant broken object level authorization (BOLA) in stigmem-node exposes quarantined facts across tenant boundaries on multi-tenant deployments. A tenant administrator holding only a standard tenant write capability can list, read, and admit or reject quarantined facts belonging to any other tenant on the same node via the /v1/quarantine endpoints - bypassing isolation enforced by the stigmem-plugin-multi-tenant plugin. No public exploit identified at time of analysis; no CISA KEV listing. Default single-tenant deployments are entirely unaffected regardless of version.
Cross-tenant broken object level authorization in stigmem-node before 0.9.0a12 allows an authenticated tenant in a multi-tenant deployment to corrupt RTBF tombstone records and trigger tenant-blind fact suppression. The root cause is twofold: the issue_tombstone function hardcoded the tenant to 'default' instead of reading it from the caller's identity, and the tombstone read-suppression path lacked a tenant_id predicate, causing deletion records to be misattributed and tombstone filtering to operate across all tenants indiscriminately. The impact is limited to deployments running the opt-in stigmem-plugin-multi-tenant; a vendor-released patch exists at 0.9.0a12, and no public exploit has been identified at time of analysis.
Function library integrity in ArcadeDB 26.7.3 and earlier can be silently tampered by any authenticated low-privilege database user because the UPDATE_SCHEMA permission gate is bypassed when a DEFINE FUNCTION statement targets an already-existing library rather than creating a new one. Attackers holding only basic database credentials can overwrite or inject SQL or Cypher function logic authored by administrators, poisoning business logic, data transformations, or access-control routines that depend on those functions. No active exploitation is confirmed (no CISA KEV listing), but the low attack complexity and network reachability (CVSS 4.0 AV:N/AC:L/PR:L) make this a genuine priority for any multi-user ArcadeDB deployment.
Principal-type confusion in Vikunja through 2.4.0 allows an attacker holding a valid link-share JWT to impersonate arbitrary user accounts by exploiting numeric ID collisions between LinkSharing principals and user records. Three permission-check code paths lack type guards, causing the application to treat a LinkSharing principal whose id equals N as the user with users.id == N. With a crafted link-share token, an attacker can remove victims from teams, enumerate and delete bot user accounts, or read team membership rosters. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
Two-factor authentication bypass in phpMyFAQ before 4.1.7 lets an attacker who already knows a valid password defeat the TOTP second factor through unbounded brute force. Because the five-attempt failure counter is stored per session and reset on every successful password re-authentication (CWE-307), an attacker can loop - grab a fresh session cookie, re-enter the known password, and get five more guesses - until the 6-digit TOTP is guessed, yielding full account takeover. Reported by VulnCheck with no public exploit identified at time of analysis and not listed in CISA KEV.
LDAP authentication bypass in phpMyFAQ 3.1.0-4.1.6 allows a blocked local account to be silently reactivated by authenticating via LDAP, letting previously suspended users regain full application access. The AuthLdap::create() method calls User::setStatus('active') unconditionally after any successful LDAP bind, overwriting an administratively set 'blocked' status in the database without logging the state change. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in CISA KEV; the vendor-confirmed fixed release is 4.1.7.
Two-factor authentication bypass in phpMyFAQ before 4.1.7 allows any attacker holding valid first-factor credentials to obtain a remember-me cookie prior to 2FA challenge completion, then replay that cookie to achieve full authenticated access while entirely circumventing the second-factor control. Affected deployments relying on 2FA as their primary defense-in-depth layer against credential compromise are effectively left with single-factor authentication. No public exploit code or CISA KEV listing has been identified at time of analysis, though the bypass logic is straightforward and the vulnerability is trivially reproducible given valid credentials.
Unauthenticated broken access control in the Outranking Plugin Options WordPress plugin (versions 1.1.3 and below) allows remote unauthenticated attackers to modify plugin options, resulting in high integrity impact. The root cause is CWE-862 (Missing Authorization), meaning the plugin fails to verify whether the requesting user has permission before processing option-change requests. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog, though the CVSS:3.1 vector of AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N reflects a low-barrier, fully network-exploitable condition.
Broken access control in the Stitch Express WordPress plugin (versions <= 1.9.0) allows unauthenticated network attackers to perform privileged operations by bypassing missing authorization checks (CWE-862). The CVSS vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N confirms zero-friction remote exploitation with high integrity impact, meaning unauthorized data modification or administrative action is achievable without credentials or user interaction. No public exploit code or CISA KEV listing has been identified at time of analysis; the vulnerability was disclosed by Patchstack.
Authentication bypass in the SAML Single Sign On WordPress plugin (versions 4.8.85 through below 5.4.7) enables unauthenticated network attackers to inject an arbitrary certificate into the site's SAML trust store by exploiting the plugin's failure to verify incoming SAML response signatures before persisting embedded certificates. Once stored, that attacker-controlled certificate can be promoted to the site's active trusted signing authority via a single administrator UI click, after which the attacker can forge SAML assertions and authenticate as any WordPress user, including site administrators. No public exploit code or CISA KEV listing has been identified at time of analysis; EPSS is very low at 0.11% (1st percentile), reflecting limited observed exploitation.
Account takeover in the TrueBooker WordPress plugin (all versions before 1.2.7) lets remote unauthenticated attackers change the email address of any registered user - including administrators - through AJAX actions that lack authorisation checks, then hijack the account via WordPress's standard password-reset flow. The flaw carries a CVSS 9.8 and is fixed in 1.2.7; there is no public exploit identified at time of analysis, and EPSS remains low (0.15%, 4th percentile), reflecting limited observed weaponisation despite the critical rating.
Authentication bypass in the TabaPay Gateway WordPress plugin (versions through 1.4.0) lets unauthenticated remote attackers log in as any registered user - including administrators - by abusing the payment callback handler. Because the plugin establishes a session for the account tied to a referenced order without validating the payment callback's authenticity, an attacker who can reach the callback endpoint can impersonate arbitrary accounts. No public exploit identified at time of analysis, and EPSS is low (0.15%, 4th percentile), but the flaw is trivially exploitable and CISA's SSVC framework rates it fully automatable with total technical impact.
Unauthenticated account lockout in the User Verification by PickPlugins WordPress plugin (through version 2.0.47) enables remote attackers to reset the email-verification status of any WordPress account - including administrators - by exploiting two authorization failures simultaneously: the resend-verification endpoint neither validates that the requestor is authorized to act on the specified user ID, nor binds the protective token to the targeted user. This effectively provides a remote, zero-privilege mechanism to lock any site account out of access. No public exploit code exists at the time of analysis, though SSVC classifies the attack as automatable, meaning bulk account disruption campaigns are technically feasible.
Improper access control in the Eventin WordPress plugin before 4.1.21 allows any authenticated user holding contributor-level access or higher to permanently delete arbitrary user accounts on the affected WordPress installation. The plugin's account deletion functionality omits both ownership verification and WordPress capability checks, meaning a low-privilege contributor can target and remove administrator accounts. No active exploitation has been confirmed by CISA KEV, and no public exploit code has been identified at time of analysis; however, the low technical barrier makes this a meaningful privilege-abuse risk on multi-author WordPress sites.
Unauthorized event takeover in the Eventin WordPress plugin (all versions before 4.1.21) allows any authenticated contributor-level user to modify, delete, or reassign events owned by other users - including site administrators. The flaw is a classic Insecure Direct Object Reference (IDOR) rooted in CWE-639: the plugin processes event operations using a user-supplied event identifier without verifying the requesting user actually owns or has authorization over the targeted record. No active exploitation has been confirmed (not in CISA KEV) and no public proof-of-concept code was identified at time of analysis, but the low privilege bar and mechanically simple IDOR exploitation pattern elevate real-world risk for any multi-author WordPress deployment.
Incorrect authorization in acmailer enables any authenticated low-privilege user to create a sub-account bearing full administrative privileges, effectively allowing unauthorized privilege escalation within the application. The flaw (CWE-863) bypasses the intended privilege boundary during sub-account creation, granting attackers administrator-level control over the mailing list system without requiring any elevated starting permissions. No public exploit code or CISA KEV listing has been identified at time of analysis, though the low attack complexity and high impact across confidentiality, integrity, and availability make this a serious risk where untrusted or semi-trusted users have accounts.
Unauthorized access to user chat data in Bottinelli Informatica Vedo Suite 1.2.5 is possible via an Insecure Direct Object Reference (IDOR) flaw in the api_vedo/chat REST endpoint, where the utente_chat parameter is not validated against the requester's session or authorization context. The 'Authentication Bypass' tag alongside a PR:N CVSS vector indicates the endpoint may be reachable without any valid credentials, making this a high-confidence confidentiality breach for any network-accessible deployment. No public exploit code has been confirmed in automated exploit frameworks, and the EPSS score of 0.24% (16th percentile) indicates limited observed exploitation at time of analysis, consistent with a low-prevalence niche product.
SSO account takeover in 4gaBoards prior to version 3.3.9 allows any authenticated user to overwrite backend-managed OAuth identity fields on their own account via the PATCH /api/users/:id endpoint, redirecting a victim's SSO login to the attacker's account. The root cause is a mass-assignment flaw in server/api/controllers/users/update.js that incorrectly exposed SSO provider identifiers - including Google, GitHub, Microsoft, and OIDC subject IDs and emails - to user-controlled input. No public exploit is identified at time of analysis, but the attack mechanism is mechanically straightforward given the confirmed source code diff, and exploitation fully transfers the victim's project and board access to the attacker.
Pre-account takeover in 4gaBoards before 3.3.8 allows a remote unauthenticated attacker to seize a victim's account before the victim ever logs in, by exploiting the SSO identity-linking logic. An attacker registers an unverified local account using the victim's email address; when the victim subsequently logs in via Google, GitHub, Microsoft, or OIDC SSO, the server locates the attacker's pre-registered account by email and links the verified SSO identity to it without confirming local account ownership, granting the attacker persistent password access to the now-SSO-linked account and all associated projects and data. No public exploit code or CISA KEV listing has been identified at time of analysis; the CVSS 8.8 score reflects the low attack complexity and high impact once victim interaction occurs.
