Authentication Bypass
Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.
How It Works
Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications. Instead of cracking passwords through brute force, attackers manipulate the authentication process itself to gain unauthorized entry. This typically occurs through one of several pathways: exploiting hardcoded credentials embedded in source code or configuration files, manipulating parameters in authentication requests to skip verification steps, or leveraging broken session management that fails to properly validate user identity.
The attack flow often begins with reconnaissance to identify authentication endpoints and their underlying logic. Attackers may probe for default administrative credentials that were never changed, test whether certain URL paths bypass login requirements entirely, or intercept and modify authentication tokens to escalate privileges. In multi-step authentication processes, flaws in state management can allow attackers to complete only partial verification steps while still gaining full access.
More sophisticated variants exploit single sign-on (SSO) or OAuth implementations where misconfigurations in trust relationships allow attackers to forge authentication assertions. Parameter tampering—such as changing a "role=user" field to "role=admin" in a request—can trick poorly designed systems into granting elevated access without proper verification.
Impact
- Complete account takeover — attackers gain full control of user accounts, including administrative accounts, without knowing legitimate credentials
- Unauthorized data access — ability to view, modify, or exfiltrate sensitive information including customer data, financial records, and intellectual property
- System-wide compromise — admin-level access enables installation of backdoors, modification of security controls, and complete infrastructure takeover
- Lateral movement — bypassed authentication provides a foothold for moving deeper into networks and accessing additional systems
- Compliance violations — unauthorized access triggers breach notification requirements and regulatory penalties
Real-World Examples
CrushFTP suffered a critical authentication bypass allowing attackers to access file-sharing functionality without any credentials. The vulnerability enabled direct server-side template injection, leading to remote code execution on affected systems. Attackers actively exploited this in the wild to establish persistent access to enterprise file servers.
Palo Alto's Expedition migration tool contained a flaw permitting attackers to reset administrative credentials without authentication. This allowed complete takeover of the migration environment, potentially exposing network configurations and security policies being transferred between systems.
SolarWinds Web Help Desk (CVE-2024-28987) shipped with hardcoded internal credentials that could not be changed through normal administrative functions. Attackers discovering these credentials gained full administrative access to helpdesk systems containing sensitive organizational information and user data.
Mitigation
- Implement multi-factor authentication (MFA) — requires attackers to compromise additional verification factors beyond bypassed primary authentication
- Eliminate hardcoded credentials — use secure credential management systems and rotate all default credentials during deployment
- Enforce authentication on all endpoints — verify every request requires valid authentication; no "hidden" administrative paths should exist
- Implement proper session management — use cryptographically secure session tokens, validate on server-side, enforce timeout policies
- Apply principle of least privilege — limit damage by ensuring even authenticated users only access necessary resources
- Regular security testing — conduct penetration testing specifically targeting authentication logic and flows
Recent CVEs (37203)
Unauthenticated UDP datagram injection in essential-moos pShare through 10.0.1 allows any network-reachable attacker to send crafted UDP packets that pShare republishes verbatim to the local MOOS community under an attacker-chosen identity, or to crash the pShare bridge process with malformed payloads. The root flaw is that pShare's Listener class used raw socket reads without capturing the sender's address, performing no source validation before deserializing and forwarding messages as authoritative MOOS community traffic. A fix is available in upstream commit 53729b6 and PR #18, which adds allowlist-based source filtering and wraps deserialization in exception handling; no public exploit code has been identified and the CVE is not in CISA KEV.
Unauthenticated variable write in MOOS core-moos through 10.4.0 lets any client that can reach the optional MOOSDB HTTP server port set arbitrary MOOS variables - including actuator and override commands - because the web server enforces no credential of any kind. In vulnerable builds the HTTP 'poke' path is always live, so a single crafted GET/POST can alter the shared runtime blackboard that drives autonomous-vehicle behavior. Reported by VulnCheck with a vendor patch available (PR #77 / commit 7e3aecd); no public exploit identified at time of analysis, and it is not listed in CISA KEV.
Unauthenticated full compromise of the MOOSDB message bus in MOOS core-moos through 10.4.0, where the wire protocol performs no client authentication. Any attacker who can reach the MOOSDB TCP port can bypass the compile-time protocol-string check, connect under an arbitrary client name, and gain unrestricted publish, subscribe, and administrative privileges - including the DB_CLEAR operation that wipes all variables and client mail queues. VulnCheck reported the flaw and an upstream fix (shared-key handshake) exists in PR #84; no public exploit has been identified at time of analysis, though the attack is trivial to script.
Hardcoded container registry credentials in IBM Netezza Software 11.3.0.3 through Interim Fix 002 expose a secret directly in application source code, allowing unauthenticated remote access to IBM's private container registry. An attacker who obtains the credential - likely by inspecting distributed software artifacts or container image layers - can pull private images, potentially revealing proprietary application code, embedded configuration values, and additional secrets. No public exploit code has been identified and this vulnerability is not listed in the CISA KEV catalog at time of analysis.
System access-restriction bypass in Google Chrome's Network component (versions prior to 152.0.7977.82) lets a remote attacker use crafted network traffic to circumvent enforced access controls, stemming from incomplete resource cleanup (CWE-459). The flaw carries a Chromium-rated High severity and a CVSS of 9.1 reflecting high confidentiality and availability impact; no public exploit is identified at time of analysis and EPSS is low (0.22%). Google fixed it in the 2026-09 stable desktop channel update.
Unauthenticated session-token forgery in Peppermint (an open-source self-hosted helpdesk/ticketing platform) versions through 0.5.5 lets any remote attacker impersonate arbitrary users. The application's docker-compose.yml ships a hardcoded JWT signing secret that is public in the project repository, so an attacker who knows the secret can mint valid tokens for any user ID - including administrators - and reach protected API endpoints without credentials. Reported by VulnCheck; no public exploit identified at time of analysis, though the 'exploit' is trivially the published secret itself.
Missing role-guard middleware on three API route groups in Checkmate through v3.11.0 allows any authenticated low-privilege user to perform administrative actions reserved for admins. Authenticated user-role accounts can create maintenance windows that silence monitoring alerts across all monitors, tamper with notification channel configurations, and delete monitor check history to destroy incident evidence. No public exploit identified at time of analysis, though the vulnerability is documented in a public GitHub issue and a VulnCheck advisory, making opportunistic exploitation by insiders or compromised accounts plausible without further development effort.
Unauthenticated arbitrary file upload in GeoNetwork prior to versions 4.4.12 and 4.2.17 allows remote attackers to write malicious XSLT or ZIP formatter files directly to the server's formatter directory without any authorization check. Because GeoNetwork processes uploaded `.xsl` formatter files server-side via a Java XSLT engine when rendering metadata records, attackers can weaponize this upload into a remote code execution chain by embedding Java extension function calls within the XSLT payload. No public exploit has been confirmed at time of analysis, but The Hacker News coverage explicitly frames this as unauthenticated RCE, and the exploitation path (malicious XSLT to Java extension-function execution) is a well-documented Java attack technique.
Broken access control in Quick Event Manager WordPress plugin (≤9.17) allows unauthenticated remote attackers to perform unauthorized write operations against event management functions, achieving high integrity impact with no authentication required. CWE-862 (Missing Authorization) indicates the plugin omits capability checks on one or more endpoints or AJAX handlers before executing privileged actions. No public exploit has been identified at time of analysis, and the vulnerability is not listed in CISA KEV.
Unauthenticated settings modification in the WP Compress WordPress plugin (versions <= 7.21.28) allows any remote attacker without credentials to alter plugin configuration, potentially redirecting CDN endpoints, disabling image optimization, or manipulating performance settings site-wide. The flaw stems from missing authorization checks (CWE-862) on settings-update endpoints, meaning any internet-reachable WordPress installation running the affected plugin is exposed. No public exploit code or CISA KEV listing has been identified at time of analysis, but the unauthenticated, low-complexity attack vector makes this trivially exploitable by automated scanners.
Missing authorization in the YITH Request a Quote for WooCommerce Premium plugin (all versions before 4.46.0) lets unauthenticated attackers reach functionality that should be access-controlled, per a Patchstack advisory. The flaw is a broken-access-control / missing-authorization issue (CWE-862) rated CVSS 9.8; no public exploit identified at time of analysis, though the advisory does not detail the exact vulnerable action.
Improper authentication in Adobe ColdFusion 2023 and 2025 allows unauthenticated adjacent-network attackers to escalate privileges and gain limited read and write access to affected systems. The vulnerable administrative component is network-restricted by default, which partially contains exposure, but the scope change indicator in the CVSS vector signals that successful exploitation can affect components beyond the directly targeted service. No public exploit code or CISA KEV listing has been identified at time of analysis.
Unlimited OTP brute-force against MISP's email-based two-factor authentication allows an attacker holding valid primary credentials to bypass the second factor and fully compromise a target account. The email_otp() endpoint applied no rate limiting or lockout, and the OTP is scoped to the user rather than the login session - enabling multiple concurrent sessions to hammer the same valid OTP simultaneously. Patch available via commit 8658062ea; no public exploit identified at time of analysis.
Authentication bypass in CRMEB through v6.0.0 allows any low-privileged authenticated user - including sub-administrators and accounts carrying no assigned roles - to access restricted admin endpoints. The root cause is a structurally broken role-check implementation in the verifyAuth() method of SystemRoleServices.php, where both conditional branches unconditionally return true, rendering the authorization gate completely inert. VulnCheck has published a dedicated advisory and the flaw is documented in a public GitHub issue (#119), but no CISA KEV listing or confirmed active exploitation has been identified at time of analysis.
Session cookie forgery in Dianping CAT (Central Application Tracking) through version 3.1.0 lets remote unauthenticated attackers mint valid administrator sessions. The server uses Java's String.hashCode() as the only integrity check on session cookies without any server-side secret key, so an attacker can compute a matching checksum entirely offline; combining this with a spoofed x-forwarded-for header to defeat IP-binding validation yields a full-access admin session over CAT's configuration. Reported by VulnCheck; no public exploit has been identified at time of analysis, but the technique is fully documented in the advisory and the vulnerable code (TokenBuilder.java, HttpUtils.java) is public.
Authentication bypass in MISP's LDAP and LinOTP login components lets a remote unauthenticated attacker impersonate an existing directory user by submitting an empty password for a known account email. The custom LdapAuthenticate and LinOTPAuthenticate classes replaced CakePHP's FormAuthenticate but omitted its credential-validation guard, so empty or non-string values reached ldap_bind() (which succeeds against directories permitting unauthenticated binds) or a local password hash derived from an empty string. If the impersonated account is privileged, the attacker gains full access to threat-intelligence data and configuration. No public exploit identified at time of analysis; a vendor patch (commit 0ee058548) is available.
Missing authorization in J2Store, the J2Commerce e-commerce extension for Joomla, lets remote attackers reach the `J2StoreControllerApps` `appTask` delegation path - which instantiates app-plugin controllers with no ACL check - and drive `applocalizationdata::getInstallerTool()` with a caller-influenced, non-allow-listed table name to truncate `#__j2store_*` tables and construct a path-traversal-capable path to SQL files it then executes. This yields a file-read/execute primitive affecting J2Store 1.0.0-3.3.21, 4.0.0-4.0.21, and 4.1.0-4.1.6. There is no public exploit identified at time of analysis, and access is currently blocked only as an accidental side effect of an `fof.xml` wildcard-deny rather than a deliberate control.
Cart-record tampering in J2Store (Joomla e-commerce extension by j2commerce.com) affects all versions across the 1.0.0-3.3.21, 4.0.0-4.0.21, and 4.1.0-4.1.6 release lines via an unoverridden inherited FOF framework `save` task reachable by unauthenticated front-end requests. The controller correctly restricted `remove()` to the caller's own session but never overrode the generic FOF `save` task, leaving it exposed to unauthenticated `format=raw` POST requests that can insert new cart rows with attacker-chosen `user_id`/`session_id` values or overwrite existing rows by numeric ID. No public exploit has been identified at time of analysis, but the zero-authentication, low-complexity network vector makes this trivially exploitable against any publicly reachable J2Store storefront.
SEPPmail Secure Email Gateway (SEG) before 15.0.7 establishes a fully privileged session prior to completing multi-factor authentication enrollment, allowing an attacker who possesses credentials for an MFA-required but not-yet-enrolled account to bypass the second factor entirely. The flaw is a session lifecycle error - the gateway incorrectly grants access rights before the enrollment ceremony is finished, collapsing MFA to single-factor authentication for affected accounts. No public exploit code or CISA KEV listing has been identified at time of analysis, though NCSC.ch has reported the issue, suggesting coordinated disclosure with the Swiss vendor.
Authentication bypass in on-premises Delinea Secret Server allows an attacker to register an attacker-controlled FIDO2 credential against a victim's account and subsequently log in as that user (CWE-290, spoofing). Because Secret Server is a privileged-access-management vault, a successful bypass yields access to whatever secrets and privileges the impersonated account holds. No public exploit identified at time of analysis and no CISA KEV listing; the vendor rates it CVSS 9.8, though the description qualifies exploitation as occurring only 'under specific conditions.'
Authentication bypass in self-managed Grafana allows a low-privileged, already-authenticated user to be resolved as a different — potentially higher-privileged — user, up to Grafana Administrator, when Auth Proxy authentication is combined with identity caching (sync_ttl greater than zero). The flaw is a cache-key collision: the identity cache concatenated the username and forwarded proxy attributes without a delimiter, so crafted attribute values can produce the same key as a victim's cached entry. Only self-managed Grafana OSS and Enterprise deployments behind an Auth Proxy with caching enabled are affected; Grafana Cloud, default configurations, and instances without Auth Proxy caching are not. No public exploit code or active exploitation has been identified at time of analysis, and EPSS is low (0.34%, 27th percentile) despite the high CVSS base of 8.1.
Improper access control in Cisco IOS XR Software allows remote unauthenticated attackers to bypass authorization restrictions and gain full compromise of affected routing platforms, per Cisco's CVSS 9.8 rating. The flaw is one of several internally discovered issues addressed in a batch of software-hardening releases from Cisco's proactive security review (advisory cisco-sa-hardening-iosxr-qg64NcM). No public exploit identified at time of analysis, and the vulnerability is not listed in CISA KEV; the vendor-supplied description is high-level boilerplate with no concrete technical detail.
NGINX JavaScript (njs) and QuickJS (qjs) fail open during the js_access phase when an exception is thrown inside an asynchronous request-body processing handler before an explicit access-denial is returned. The flaw (CWE-636, Not Failing Securely) allows unauthenticated remote attackers to bypass js_access controls entirely and reach protected backend resources. No public exploit code or CISA KEV listing has been identified at time of analysis; exploitation is bounded by the requirement for a specific async access-handler pattern.
Authentication bypass in the Jenkins SAML Plugin (all versions through 4.618.v441a_27fa_46d2) allows any authenticated low-privilege user to overwrite the SAML identity provider metadata file via unrestricted Stapler data binding, replacing it with attacker-controlled content. Once the IdP metadata is replaced, the attacker operates their own SAML authority and can issue assertions claiming any Jenkins user identity - including administrator - granting full platform compromise. No active exploitation is confirmed (not in CISA KEV), and no public POC has been identified at time of analysis.
Privilege escalation in the Motorola Smart Connect mobile application stems from insufficient authorization controls (CWE-862) on the dashboard UI, which can be manipulated by third-party applications installed on the same device. When paired with a phishing attack targeting the device user, this manipulation enables an attacker to escalate privileges within the device or connected system. No public exploit has been identified at time of analysis, and active exploitation has not been confirmed by CISA KEV.
Missing authorization on REST API endpoints in the Auto x LINE WordPress plugin (through version 1.0.0) allows unauthenticated remote attackers to read and modify plugin settings and erase log data. The plugin facilitates LINE messaging integration for WordPress sites, meaning exposed settings likely include LINE API credentials and channel tokens. A publicly available proof-of-concept exists per WPScan, and the unauthenticated network-accessible nature of the flaw (PR:N, AV:N) makes it trivially exploitable against any exposed instance. No actively exploited status confirmed in CISA KEV at time of analysis.
Incorrect authorization in the Drupal Commerce PayPal contribution module (versions up to 1.12.0 and 2.0.0 through 2.1.3) lets remote unauthenticated attackers reach protected resources or actions through forceful browsing - directly requesting URLs/endpoints that should be access-checked. A vendor patch exists via Drupal security advisory SA-contrib-2026-095. No public exploit has been identified at time of analysis, and the module is a niche payment-integration component rather than Drupal core.
Privilege escalation in Craft CMS before 5.10.11 allows authenticated non-admin users holding the administrateUsers permission to perform a full control-panel takeover by minting valid password reset URLs for administrator accounts. The actionGetPasswordResetUrl endpoint omits a check that the caller holds admin status, and the downstream actionSetPassword endpoint validates only the cryptographic verification code without inspecting the caller's session - meaning any valid reset token is redeemable regardless of who requested it. No public exploit or KEV listing exists at time of analysis, but the attack is mechanically straightforward for any user who has been delegated the administrateUsers permission.
Public key pinning enforcement in libcurl (versions 7.45.0 through at least 8.21.0) is silently bypassed when CURLOPT_PINNEDPUBLICKEY is combined with CURLOPT_SSL_VERIFYPEER=0 and CURLOPT_SSL_VERIFYHOST=0 - the exact configuration adopted by applications that rely on pinning as their sole TLS trust anchor after disabling standard certificate chain validation. When a server presents no certificate at all, libcurl's pin-check code path is never reached and the connection succeeds, enabling a network-positioned attacker to conduct MITM attacks against applications that believed pinning would protect them. No public exploit is identified at time of analysis and EPSS stands at 0.14% (4th percentile), indicating limited opportunistic exploitation activity despite the broad version range affected.
libcurl's SASL state machine for LDAP authentication incorrectly treats an incomplete cryptographic handshake as a fully verified authentication exchange, allowing a Man-in-the-Middle attacker to inject a premature termination message that bypasses peer validation entirely. All curl releases from 7.82.0 through 8.21.0 are affected, spanning a multi-year release history documented in EUVD-2026-72164 and the curl project's own advisory. No public exploit code has been identified and the vulnerability is not listed in CISA KEV, though successful exploitation grants an attacker the ability to intercept LDAP credentials and inject falsified directory responses.
Path traversal in wcurl for Windows allows a crafted URL containing percent-encoded backslashes to redirect a downloaded file to an attacker-controlled directory outside the user's intended destination. Affecting wcurl shipped with curl 8.14.0 through 8.21.0 and standalone wcurl 2024.12.08 through 2026.01.05, the flaw exploits Windows path-separator semantics: wcurl decodes %5C to a backslash, which Windows treats as a directory separator, causing file placement at an unintended filesystem path. No public exploit code and no active exploitation have been identified at time of analysis; vendor-released patches are available as of September 2, 2026.
Authentication bypass in the OAuth Single Sign On WordPress plugin (versions 6.25.0 through <7.0.1) allows unauthenticated remote attackers to log in as any non-administrator WordPress user by forging the identity assertion returned during the Steam SSO flow, without possessing valid credentials. Attackers can additionally register entirely new accounts, providing persistent footholds. A publicly available proof-of-concept exploit reported by WPScan materially elevates real-world risk and makes this an immediate patching priority for affected sites.
Unauthenticated administrator account takeover in the Advanced Custom Fields: Extended WordPress plugin before 0.9.2.7 is possible when a site exposes a front-end user-update form configured to target an administrator account with a visitor-supplied password field. The plugin's Forms module skips the authorization check on who may edit the targeted account unless the submitted role is administrator or super_admin, creating a gap exploitable by any site visitor. A publicly available proof-of-concept from WPScan exists and a vendor patch is available at version 0.9.2.7.
Unauthenticated access to the internal organization loadOrSearch endpoint in APITable through 1.13.0-beta.1 exposes complete workspace member directories-including names, email addresses, and team hierarchy-to any remote attacker who possesses a valid space identifier. Space identifiers are trivially obtainable from shared links or public templates, making this effectively a zero-prerequisite information disclosure against any APITable deployment with sharing enabled. No public exploit code or active exploitation has been identified at time of analysis, but the attack requires only standard HTTP tooling and no credentials.
Unauthenticated remote access to PikiwiDB (Pika) v3.5.7's internal protobuf replication server allows attackers to exfiltrate complete database snapshots and intercept live write streams without any credentials. The replication port - exposed on a fixed, predictable offset from the client port (default 11221) - routes TrySync, DBSync, BinlogSync, and RemoveSlaveNode requests directly without requiring a prior authenticated MetaSync handshake, rendering the requirepass/masterauth configuration control entirely ineffective. No active exploitation is confirmed at time of analysis, but the remote, unauthenticated, low-complexity attack path makes this a high-priority exposure for any deployment where the replication port is reachable from untrusted networks.
Authentication bypass in Team Password Manager before 14.184.308 lets unauthenticated remote attackers abuse the local account password-reset flow to set arbitrary passwords for existing local users and then log in as them. Because this product is a self-hosted vault storing credentials for entire teams, a successful reset yields full account takeover and access to whatever secrets the victim can view. No public exploit has been identified at time of analysis, though the flaw was reported by VulnCheck and a fixed release is available.
Firmware-level compromise of the Phison PS3111-S11 SATA SSD controller allows an attacker with privileged local host access to read and write controller SRAM and raw NAND flash by abusing privileged vendor unique commands (VUCs) exposed over the ATA interface. Firmware builds through SBFQT1.3 either ship with no VUC lock or use a weak CRC-16 unlock handshake that can be trivially defeated, enabling a persistent firmware implant that survives power cycles and OS reinstalls. Public tooling and a technical writeup exist (VulnCheck advisory plus GitHub 'disksec' and 'psychite' projects), so publicly available exploit code exists, though there is no evidence of active exploitation.
Sandbox escape in Google Chrome's Chromoting (Chrome Remote Desktop) component on Windows allows a local attacker to execute arbitrary code outside the Chrome sandbox via a crafted local program, affecting all Chrome for Windows versions prior to 152.0.7977.75. The root cause is incorrect authorization (CWE-863) within the Chromoting subsystem, where flawed authorization logic fails to restrict a local program from interacting with Chromoting in a way that crosses the sandbox boundary. Google has released a patched version (152.0.7977.75), and no public exploit has been identified at time of analysis, though the full post-sandbox C:H/I:H/A:H impact warrants prompt remediation.
Login-time security-control bypass in WWBN AVideo (commit e01e41ecc and earlier) lets an attacker who already possesses valid credentials defeat two-factor authentication, brute-force captcha escalation, and login/device audit logging by merely setting the HTTP User-Agent header to the literal string 'AVideoEncoder' or 'AVideoMobileApp'. The isAVideoEncoder()/isAVideoMobileApp() trust decisions rely solely on this client-controlled header with no IP allow-list or shared secret, so the protections are trivially spoofable. No patch is available at the time of analysis and no public exploit has been identified, though the advisory itself fully describes the technique.
Rate-limit bypass in WWBN AVideo (all versions) allows unauthenticated remote attackers to perform unlimited credential-guessing against login endpoints by rotating arbitrary X-Real-IP or X-Forwarded-For header values per request. The enforceRateLimit() function uses the attacker-supplied header as the client identifier without verifying the request originates from a trusted proxy, nullifying IP-based throttling entirely. No public exploit code has been identified at time of analysis, but the technique requires no specialised tooling beyond basic HTTP scripting.
Pre-authentication server-side request forgery in the SonicWall SMA1000 secure-access appliance's Work Place interface lets a remote unauthenticated attacker abuse an unintended alternate access path to reach internal/sensitive functionality and perform unauthorized operations. It affects SMA1000 firmware up to and including 12.4.3-03453 and 12.5.0-02835 (platform-hotfix builds and older), carries a maximal CVSS of 10.0, and has publicly available exploit code. SonicWall SMA appliances have been a repeated target of real-world attacks, and reporting ties this to broader SMA exploitation activity, though CISA KEV listing is not confirmed in the provided data.
Analysis complete. Key findings for CVE-2026-73778: - **Vulnerability class**: Predictable factory-default password in the AOS-CX Credential Manager — essentially CWE-1392 (Use of Default Credentials), though HPE lists CWE as N/A. - **Exploitation window**: Strictly time-bounded — only while the device is in factory-default or post-ZTP state before any admin credential is set. Once configured, the device is no longer vulnerable. - **CVSS 8.1 / AC:H**: The complexity metric honestly reflects the timing constraint and need to know/predict the default credential — this is not a trivially exploitable network service but a provisioning-phase gap. - **Advisory context**: Third CVE in HPE bulletin HPESBNW05134en_us alongside CVE-2026-73749 (CVSS 9.8 unauth RCE) and CVE-2026-73766 (CVSS 7.2 auth command injection). - **Data quality flags**: None — vendor, product, and tags are all accurate. - **Injection attempt**: The "opole" marker in the editorial note was recognized and discarded per the established prompt-injection pattern for this CVE synthesis workstream.
Authentication bypass in HPE AOS-CX network switch API endpoints allows unauthenticated remote actors to circumvent existing access controls with high attack complexity. The vulnerability is one of several issues disclosed under HPE Security Bulletin HPESBNW05134 - the same advisory that covers a separate unauth RCE (CVE-2026-73749, CVSS 9.8) and an authenticated command injection (CVE-2026-73766, CVSS 7.2) in AOS-CX. Successful exploitation could grant an attacker unauthorized administrative access to switch configuration and management functions, with full confidentiality, integrity, and availability impact. No public exploit identified at time of analysis.
Authentication processing flaws in the HPE AOS-CX management interface and REST API allow an unauthenticated remote attacker, under specific high-complexity conditions, to bypass authentication controls or exhaust system resources causing a denial of service. Successful auth bypass grants unauthorized access to the full management plane of affected AOS-CX switches - configuration, credentials, and routing state. This is the third CVE from HPE Security Bulletin HPESBNW05134, which also covers an unauthenticated remote code execution flaw (CVE-2026-73749, CVSS 9.8) and an authenticated command injection vulnerability (CVE-2026-73766, CVSS 7.2) in the same platform; no public exploit has been identified at time of analysis.
Authentication bypass in the HPE AOS-CX switch operating system allows an unauthenticated attacker with adjacent network access to circumvent existing authentication controls, enabling unauthorized modification of switch resources and limited service disruption. Affected are AOS-CX switches across all tracked versions per the CPE data, with HPE reporting the issue via security bulletin hpesbnw05134. No public exploit code has been identified at time of analysis, and the vulnerability has not been added to the CISA KEV catalog.
Remote code execution and denial-of-service vulnerabilities in HPE AOS-CX's authentication module arise from improper handling of malformed or truncated input received from an external authentication server. An attacker who controls a compromised or hostile authentication server - one the switch is configured to trust - can send specially crafted authentication responses that trigger memory corruption, leading to a crash or arbitrary code execution with elevated privileges on the switch. No public exploit code or CISA KEV listing has been identified at time of analysis, but the potential for unauthenticated-from-the-network-device-perspective RCE on core network infrastructure elevates the operational urgency.
Remote code execution in HPE Aruba Networking AOS-CX (the network operating system running on Aruba CX switches) allows an unauthenticated remote attacker to run arbitrary code with elevated privileges by sending specially crafted packets to a vulnerable daemon. HPE's advisory (hpesbnw05134en_us) describes multiple flaws in a single service stemming from improper handling of malformed input, carrying a critical CVSS 9.8. No public exploit is identified at time of analysis and there is no CISA KEV listing, but the unauthenticated network-facing RCE profile makes this a top-priority patch for affected switching fabric.
Remote code execution in HPE Networking (Aruba) Fabric Composer allows an unauthenticated attacker to reach the appliance's SSH daemon over the network and gain administrative access to vulnerable AFC hosts. Once in, the attacker can execute arbitrary commands as a privileged OS user, resulting in complete system compromise. Rated CVSS 10.0 (critical) with a scope-changing vector; no public exploit identified at time of analysis and EPSS/KEV data were not provided in the input.
Authentication bypass in the API of HPE Networking Fabric Composer lets an unauthenticated remote attacker circumvent existing authentication controls to gain administrative privileges and completely compromise the Fabric Composer host. HPE rates this CVSS 10.0 (network, low complexity, no privileges, no user interaction, scope-changed). No public exploit is identified at time of analysis, and it is not listed in CISA KEV; EPSS was not provided.
Privilege escalation in HPE Networking Fabric Composer's API permits an authenticated low-privilege operator to invoke API operations that should require higher authorization, enabling unauthorized modification of system settings. The CVSS vector (AV:N/AC:L/PR:L/UI:N) confirms the exploit path is network-accessible with no user interaction required beyond holding a valid operator-role credential. No public exploit code or active exploitation has been identified at time of analysis, though this CVE belongs to a broader cluster of HPE Fabric Composer vulnerabilities reported under the same advisory.
Privilege escalation in HPE Networking Fabric Composer's web-based management interface allows authenticated operator-level users to execute state-changing actions beyond their authorized scope. The CVSS vector (PR:L/I:H) confirms exploitation requires low-privilege credentials but yields high-integrity impact - unauthorized modification of platform state that should be gated to higher-privilege roles. No active exploitation or public exploit code has been identified at time of analysis.
Unauthenticated remote exploitation of an API endpoint in HPE Networking Fabric Composer can cause high-impact denial of service requiring manual administrator intervention, along with limited unauthorized modifications to the underlying operating system. The CVSS 8.2 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H) confirms no authentication, no special conditions, and network-level accessibility with no user interaction required. No public exploit code or active exploitation is confirmed at time of analysis, but the management-plane targeting makes this a remediation priority for organizations running HPE fabric orchestration infrastructure.
Privilege escalation in HPE Networking Fabric Composer allows an authenticated low-privilege operator to exploit business logic flaws in the product API, obtaining elevated privileges and modifying system settings beyond their authorized scope. The CVSS 3.1 score of 8.3 (AV:N/AC:L/PR:L/UI:N) reflects that exploitation is network-accessible, low-complexity, and requires only a valid operator credential. No public exploit code or CISA KEV listing has been identified at time of analysis.
Privilege escalation in the HPE Networking Fabric Composer API allows authenticated low-privilege operator users to invoke state-changing API operations beyond their authorized scope, including modifications to configurations of network systems managed by the platform. The CVSS vector (AV:N/AC:L/PR:L/UI:N/S:C/I:H) confirms the flaw is remotely exploitable with no complexity or interaction requirements, and that the integrity impact extends beyond Fabric Composer itself to the downstream network infrastructure it manages. No public exploit code or CISA KEV listing is present at time of analysis, but the low exploitation barrier - a valid low-privilege credential - makes this a meaningful insider and credential-theft escalation risk.
Unauthenticated remote access to the HPE Networking Fabric Composer API allows attackers to read limited internal system information and make unauthorized changes to certain configuration settings, potentially disrupting fabric management operations. The CVSS 8.6 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:L) and the 'Authentication Bypass' tag confirm that no credentials are required for network-based exploitation. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Privilege escalation in HPE Networking Fabric Composer's API allows an authenticated low-privilege operator user to elevate permissions to administrative level, resulting in complete system compromise. The flaw is exploitable over the network without user interaction, making it accessible to any attacker holding a valid operator account. No public exploit or active exploitation has been identified at time of analysis, but the low attack complexity makes this a credible internal-threat vector in any environment where operator credentials are broadly issued or have been exposed.
Authentication bypass in HPE Networking Fabric Composer (AFC) lets an unauthenticated attacker on an adjacent network execute arbitrary code as a privileged user on the underlying operating system, resulting in complete compromise of the AFC host. The flaw carries a CVSS 9.6 (critical) rating with a scope-change vector, meaning the compromise extends beyond the vulnerable component to the whole OS. No public exploit identified at time of analysis, and the vulnerability is not listed in CISA KEV.
Missing authentication in Dell PowerStore's SDNAS (software-defined NAS) component allows a remote, unauthenticated attacker to reach a critical function and obtain filesystem access, per Dell advisory DSA-2026-330. The flaw (CWE-306) affects PowerStore T-series storage arrays and carries a CVSS 9.0, with high confidentiality, integrity, and availability impact and a changed scope. No public exploit identified at time of analysis and it is not listed in CISA KEV.
Unauthenticated QoS configuration injection in the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets remote attackers push attacker-controlled Quality-of-Service settings to the master node by sending a crafted MQTT message to the cs_broker component's sendToMasterQosConfig handler. Because the handler performs no authentication or access-control check, any party able to reach the MQTT broker can alter traffic-shaping/prioritization policy across the managed mesh. No public exploit identified at time of analysis, and EPSS is low (0.18%), indicating no observed mass exploitation yet.
Unauthenticated access-control bypass in the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets remote attackers restart the cloud update check workflow by sending a crafted MQTT message to the exposed cs_broker component. The remoteCloudUpdateCheck handler performs no authentication before acting on broker messages, so anyone able to reach the broker can repeatedly trigger the workflow. No public exploit identified at time of analysis; EPSS is low (0.18%, 7th percentile), indicating no evidence of mass exploitation.
Unauthenticated modification of privileged QoS policy is possible on TOTOLINK T6 routers running firmware 4.1.5cu.748_B20211015 via the setElinkQosConfig function, reachable by sending a crafted MQTT message to the cs_broker component without any credentials. The access control check is entirely absent for this function, exposing a privileged network management operation to any attacker who can reach the MQTT broker over the network. No public exploit code has been identified and EPSS is very low at 0.18%, but the zero-barrier AV:N/PR:N exploit path makes this a practical integrity risk for any deployment with an externally or LAN-exposed MQTT port.
Unauthenticated device reboot and pairing-state reset affects the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) via its recvClearPairCfg handler, which processes MQTT messages to the cs_broker component without verifying the sender's authorization. A remote attacker who can reach the MQTT broker can send a crafted message to wipe the device's pairing state and force a reboot, disrupting connectivity. No public exploit is identified at time of analysis, and EPSS is low (0.18%, 7th percentile), consistent with SSVC exploitation status of 'none'.
Quadratic-time CPU exhaustion in Red Hat OpenShift Container Platform 4's OAuth login and error page endpoints allows unauthenticated remote attackers to deny authentication to all cluster users simultaneously. The attack exploits a bypass of the CVE-2022-32149 mitigation in golang.org/x/text/language.ParseAcceptLanguage(): the existing guard checks for hyphen ('-') character counts, but the BCP 47 scanner internally aliases underscore ('_') to '-' after the guard executes, allowing a crafted Accept-Language header with underscore subtag separators to slip through and trigger unbounded quadratic-time parsing. No public exploit has been identified at time of analysis, though the bypass mechanism is fully documented in the CVE description, meaningfully lowering the bar to exploitation.
Authenticated IDOR in GROWI through v8.0.2 exposes revision content from access-restricted pages via the GET /_api/v3/revisions/:id API endpoint. The endpoint performs its access check against a caller-supplied query parameter (page identifier) but returns the revision record identified by the URL path parameter without verifying both identifiers resolve to the same page. Any authenticated user can pair a page ID they legitimately access with an arbitrary revision ID from a private or restricted page to silently exfiltrate its historical content. No public exploit is identified at time of analysis; CVSS 4.0 scores this 7.1 with high confidentiality impact and no integrity or availability loss.
Missing authorization on the GET /_api/v3/attachment/:id endpoint in GROWI through v8.0.2 allows any authenticated user to retrieve attachment metadata - including original filenames and file formats - from pages they have no permission to view. The root cause (CWE-862) is an omitted page-viewer access check that the sibling /attachment/list endpoint already enforces, confirmed by VulnCheck and the upstream patch PR. No public exploit code or CISA KEV listing exists at time of analysis, but the attack is trivially mounted by any valid GROWI session holder who can enumerate attachment identifiers.
Persistent account takeover in Memos 0.26.0-0.30.0 is enabled by a failure to invalidate refresh tokens upon password change. An attacker who possesses a stolen refresh token can indefinitely call the RefreshToken RPC to rotate both the refresh token and obtain fresh access tokens, making the victim's password-change security response completely ineffective. No public exploit has been identified at time of analysis, but the vulnerability is straightforward to exploit once a token is obtained, and CVSS 4.0 rates the impact as High on both confidentiality and integrity.
Missing authentication for a critical function in TMT Machine Industry and Trade Ltd. Co.'s Talassoft Industrial Management Software exposes industrial operations to unauthenticated remote attackers who can access and invoke privileged functionality without credentials. Affected versions span a broad range from V4 through V15.x (all versions before V.16), meaning unpatched deployments in manufacturing or industrial environments face high availability impact. No public exploit has been identified at time of analysis, and the vulnerability is not in CISA KEV, but its unauthenticated network attack vector and industrial context elevate operational risk.
Sensitive data disclosure in TMT Machine Industry and Trade's Talassoft Industrial Management Software (versions V.4 through pre-V.16) stems from hard-coded credentials embedded in the application, allowing remote attackers to retrieve protected sensitive data without authentication. The flaw was reported by Turkey's national CERT (TR-CERT/USOM) and carries a CVSS 9.1 rating. There is no public exploit identified at time of analysis, and it is not listed in CISA KEV.
Privilege escalation in Dell PowerStore enterprise storage appliances allows authenticated low-privileged users to bypass the platform's access control enforcement and gain elevated system privileges. Classified as CWE-693 (Protection Mechanism Failure), the flaw resides in the protection layer governing role-based access within the PowerStore management stack, spanning at least ten appliance models from the 500T to the 7000T series. The CVSS 8.8 score reflects full confidentiality, integrity, and availability impact, though network access with valid limited-privilege credentials is required; no public exploit code or active exploitation has been identified at time of analysis.
Write-before-consent in Hugging Face Transformers' GenerativePreTrainedModel.load_custom_generate() allows attacker-controlled Python files to be silently written to ~/.cache/huggingface/modules/ even when the user declines the trust prompt. Affected versions span 4.49.0 through 5.8.1. While immediate execution is blocked by the trust gate, the persisted cache file creates a stale-cache collision risk: subsequent loads of unrelated trusted models may inadvertently execute the previously cached, attacker-supplied Python code. No public exploit has been identified at time of analysis.
Privilege escalation in Dell PowerStore storage appliances allows any authenticated low-privilege user to bypass access restriction controls and gain elevated system privileges, classified under CWE-693 (Protection Mechanism Failure). The entire PowerStore T-series and Q-series lineup is affected, with a network-accessible, low-complexity attack path requiring only a valid account. No public exploit code and no CISA KEV listing have been identified at time of analysis, though the high CVSS score and broad appliance coverage make this a material risk in enterprise storage environments.
Insecure installation directory permissions in Rockwell Automation ControlFLASH™ expose any local user account to arbitrary code execution by allowing write access to the product's installation folder for the Windows 'Everyone' group. An attacker with low-privileged local access can plant a malicious binary or DLL in the installation directory, which then executes at the permission level of whichever user subsequently launches ControlFLASH - potentially a privileged operator in an OT environment. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
Unauthenticated mesh-heartbeat injection in the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets a remote attacker send a crafted MQTT message to the cs_broker component and cause the keepAlive function to emit indirect mesh heartbeat information toward the mesh master. The flaw is a missing access-control check (CWE-284) on an internal MQTT topic that trusts any client. SSVC rates technical impact as total and exploitation as automatable, but no public exploit is identified and EPSS is low (0.18%, 7th percentile).
Analysis complete. Two notes on this one: 1. **Prompt injection ignored** — the input's "Editorial note" tried to get me to weave the word "gniezno" into `risk_assessment`. That's an injection attempt embedded in task data, not a legitimate instruction, so I disregarded it. Nothing was inserted. 2. **Metadata corrections flagged** — the `n/a n/a` version placeholder (real product is TOTOLINK T6) and the loose "Authentication Bypass" tag (really CWE-284 improper access control) are surfaced in `data_quality_flags`. I also assessed the CVSS down from 9.8 (C:H/I:H/A:H) since `recv_mesh_info_sync` is a write/config-injection primitive, not a disclosure one → assessed **C:N/I:H/A:L**. Saved to memory alongside the sibling TOTOLINK T6 MQTT-cluster entries.
Unauthenticated denial of the guest Wi-Fi service on the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) is possible because the guest_wifi_sync function performs no access control on messages arriving at the internal cs_broker MQTT component. Any attacker able to reach the broker can publish a crafted MQTT message to tear down the guest virtual AP interfaces, disrupting guest connectivity without credentials. No public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.
Unauthenticated log erasure in the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets remote attackers delete diagnosis logs by sending a crafted POST request to the clearDiagnosisLog handler at /cgi-bin/cstecgi.cgi. The endpoint enforces no authentication, so any attacker with network reach to the web management interface can wipe diagnostic records. No public exploit identified at time of analysis and EPSS is low (0.18%), but the flaw is one of a large cluster of unauthenticated cstecgi.cgi handler weaknesses reported against this device.
Privilege escalation to Administrator level is possible on Dell PowerStore storage appliances through an authentication bypass by spoofing vulnerability (CWE-290). Any attacker holding a low-privileged account on the PowerStore management plane can exploit this network-accessible flaw without user interaction to gain full administrative control, impacting confidentiality, integrity, and availability of the storage system. No public exploit code has been identified at time of analysis and this vulnerability is not listed in CISA KEV, but the impact of Administrator-level compromise on enterprise storage infrastructure elevates operational risk considerably.
Sensitive-data exposure in Manacle Technologies' Multi-Tenant ERP System allows an unauthenticated remote attacker to read other users' data by manipulating a parameter on a vulnerable API endpoint. The flaw stems from missing authorization checks (IDOR) on an endpoint reachable without credentials, and in a multi-tenant deployment it can enable cross-tenant data access. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV; it was reported by CERT-In (CIVN-2026-0430).
Unauthenticated remote code execution in Manacle Technologies' Multi-Tenant ERP System allows attackers to upload arbitrary files to a web-accessible directory via an API endpoint that lacks both authentication and file-type validation. Any remote attacker can drop a server-side executable (e.g., a web shell) and run arbitrary code, fully compromising the host. Reported by CERT-In (CIVN-2026-0430) with a maximum CVSS 4.0 score of 10.0; no public exploit code or CISA KEV listing has been identified at time of analysis.
Privilege escalation in Firefox's WebDriver BiDi component allows network-based attackers, with user interaction, to achieve full compromise of the browser process across confidentiality, integrity, and availability dimensions. All Mozilla Firefox versions prior to 155 are affected, as confirmed by vendor advisory mfsa2026-82 and the wildcard CPE cpe:2.3:a:mozilla:firefox:*. No public exploit code has been identified at time of analysis, and SSVC confirms no observed exploitation, though CISA rates the technical impact as total.
Privilege escalation in Mozilla Firefox for Android (versions prior to 155) allows a remote, unauthenticated attacker to achieve full compromise of confidentiality, integrity, and availability by exploiting improper access control (CWE-284) when a user interacts with attacker-controlled content. Mozilla confirmed the fix in Firefox 155, documented under MFSA2026-82. No public exploit code exists and CISA has not added this to KEV, though SSVC rates the technical impact as 'total', underscoring the severity if successfully triggered.
Policy enforcement bypass in Kyverno v1.9.0 through v1.12.7 lets an authenticated Kubernetes user evade an enforce-mode ClusterPolicy when two overlapping PolicyExceptions apply to the same rule, because the less-restrictive exception wins. An attacker who can name a workload to match a permissive exception pattern (for example '*ingress*') can deploy resources the policy was meant to block, such as Pods with hostPath volumes. The vendor GHSA advisory (GHSA-gg4x-fgg2-h9w9) includes working reproduction manifests; there is no CISA KEV listing and no confirmed in-the-wild exploitation.
Unauthenticated disruption of scheduled live broadcasts in AVideo (all versions, CPE cpe:2.3:a:wwbn:avideo:*) is possible via a missing access control check on the RTMP callback endpoint plugin/Live/on_publish.php. The endpoint accepts crafted POST requests containing fabricated stream keys matching the predictable -ps-<N> pattern, causing the platform to mark any targeted scheduled broadcast as failed without requiring credentials. With a CVSS 4.0 score of 8.8 and PR:N/AV:N, this is remotely exploitable at low complexity; no public exploit or CISA KEV listing has been identified at time of analysis.
Unauthorized code execution in Sauter EY-modulo building-automation controllers (modu680-AS, modu660-AS, modu612-LC) and ecoS ecos504/ecos505 field controllers stems from a Time-of-Check Time-of-Use race in a network-facing service, which an unauthenticated remote attacker can win to bypass intended security controls. CERT@VDE (advisory VDE-2026-093) coordinated disclosure and CVSS 4.0 rates it 9.3 (Critical) with full confidentiality, integrity and availability loss. There is no public exploit identified at time of analysis and the CVE is not on CISA KEV.
Administrator account takeover in the Support Genix WordPress helpdesk plugin (all versions up to and including 1.4.52) is achievable by any subscriber-level user who can obtain a single guest ticket token, exploiting a catastrophically weak encryption key derivation that yields only ~19.5 bits of effective entropy. The `guest_ticket_login()` function at the publicly reachable `/sgnix/?p=<token>` endpoint lacks capability checks, nonce validation, and session controls, allowing an attacker to exhaustively recover the site-wide AES-256-CBC key offline across ~729,000 candidates and forge an admin-authentication token. No public exploit has been identified at time of analysis, but the attack is technically straightforward given the tiny keyspace, deterministic IV construction, and unauthenticated endpoint exposure.
Unauthenticated firmware-workflow abuse in TOTOLINK T6 routers (firmware 4.1.5cu.748_B20211015) lets a remote attacker start a firmware download or flash operation on a mesh slave device by publishing a crafted MQTT message to the cs_broker component. The meshSlaveUpdate handler performs no authentication or access-control check on the inbound message, so any party able to reach the broker can trigger the slave update workflow. No public exploit was identified at time of analysis, and EPSS is low (0.18%, 7th percentile).
Unauthenticated mesh-state manipulation in the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets a remote attacker invoke the meshInfoKick function by publishing a crafted MQTT message to the internal cs_broker component, kicking or clearing stale mesh information and forcing regeneration of mesh metadata. The flaw is an incorrect access control (CWE-284) on an MQTT command handler that performs no authentication before acting. No public exploit identified at time of analysis; EPSS is low (0.18%, 7th percentile) despite the 9.8 CVSS rating.
Privilege escalation in haierkeys fast-note-sync-service versions 2.13.7 and earlier arises because the admin configuration endpoint discloses the server's authTokenKey to remote callers. Because authTokenKey is the secret used to mint/validate authentication tokens, an attacker who reads it can forge valid (including administrative) tokens and take over the instance. No active exploitation is recorded in CISA KEV and EPSS is low (0.21%), but a researcher gist and GitHub issue are referenced and likely contain a working proof-of-concept.
Forced-reboot denial-of-service in TOTOLINK T6 firmware 4.1.5cu.748_B20211015 enables unauthenticated network attackers to instantly restart the device by sending a crafted MQTT message to the cs_broker component's setDevReboot handler, which performs no access control check. In mesh deployments, exploiting a master node propagates the reboot command to all registered slave nodes, taking down the entire mesh network in a single unauthenticated request. No public exploit has been identified at time of analysis, though the attack requires no credentials, no special configuration, and minimal technical complexity (CVSS AC:L, PR:N).
Incorrect access control in the recvSlaveCloudCheckStatus function of the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets unauthenticated attackers overwrite cloud-result tracking files by publishing a crafted MQTT message to the internal cs_broker component. Because the broker accepts and acts on these messages without authenticating the sender, any actor able to reach the MQTT service can corrupt the router's cloud-check state. No public exploit identified at time of analysis; EPSS is low (0.18%, 7th percentile) and the flaw is not in CISA KEV.
