Authentication Bypass

LinkAce versions before 2.5.3 disclose private notes to authenticated users via the web interface when viewing shared links, despite the API correctly enforcing note visibility restrictions. An authenticated user can read another user's private notes attached to internal or public links by accessing the web link detail page, resulting in unauthorized information disclosure. Version 2.5.3 patches this authorization bypass.

Varnish Cache before 8.0.1 and Varnish Enterprise before 6.0.16r12 mishandle HTTP/1.1 URLs with a root path (/) in unchecked req.url scenarios, enabling cache poisoning and authentication bypass attacks. Unauthenticated remote attackers can exploit this with moderate complexity to poison cached content or bypass authentication controls affecting downstream clients. No active exploitation has been confirmed, though the vulnerability carries a 5.4 CVSS score reflecting network accessibility and partial impact to confidentiality and integrity.

Mastodon versions 4.5.x before 4.5.8 and 4.4.x before 4.4.15 allow unauthenticated attackers with prior knowledge of a quote to prevent its correct processing on a target server, resulting in limited integrity and availability impact. The vulnerability exploits timing and knowledge of ActivityPub quote structures to disrupt social content distribution. Patches are available in Mastodon 4.5.8 and 4.4.15; versions 4.3 and earlier are unaffected due to lack of quote support.

DNS name constraint validation bypass in cryptography library versions prior to 46.0.6 allows peer names to bypass X.509 name constraint checks during certificate validation. The vulnerability arises because name constraints were applied only to Subject Alternative Names (SANs) in child certificates but not to the peer name presented during validation, permitting a certificate for bar.example.com to validate against a wildcard leaf certificate (*.example.com) even when an excluded subtree constraint for bar.example.com existed in the parent certificate. Exploitation requires an uncommon X.509 topology not typically present in the Web PKI, and no public exploit code or active exploitation has been identified.

Insecure Direct Object Reference (IDOR) in Langflow API allows authenticated users to read, modify, or delete any flow belonging to other users via unvalidated flow_id parameters in GET/PATCH/DELETE /api/v1/flow/{flow_id} endpoints. The vulnerability affects both the langflow and langflow-base Python packages, enabling attackers with valid credentials to exfiltrate sensitive data (including plaintext API keys embedded in flows), tamper with AI agent logic, or destroy other users' workflows. A vendor-released patch (PR #8956) is available. No public exploit code identified at time of analysis, though the vulnerability is straightforward to exploit given the clear description and patch differential in the advisory.

Unauthenticated remote cache poisoning in nektos/act (GitHub Actions local runner) enables arbitrary code execution by exposing the built-in actions/cache server on all network interfaces without authentication. Attackers who can reach the cache server-including from the public internet if exposed-can inject malicious cache entries with predictable keys, leading to remote code execution within Docker containers running GitHub Actions workflows. No public exploit identified at time of analysis, though EPSS data unavailable. Vendor-released patch available in act v0.2.86.

Unauthenticated stream hijacking in LibreChat versions 0.8.2-rc2 through 0.8.2-rc3 allows authenticated users to read other users' real-time chat conversations via the SSE streaming endpoint `/api/agents/chat/stream/:streamId` without ownership verification. An attacker with valid credentials can enumerate or guess stream IDs to intercept sensitive messages, AI-generated responses, and tool invocation data from arbitrary users. The vulnerability was patched in version 0.8.2.

Fleet device management software prior to version 4.81.0 allows privilege escalation through email validation bypass in the user invitation flow. An attacker with a valid invite token can create an account using an arbitrary email address while retaining the role permissions granted by the invite, potentially obtaining global admin access. No public exploit code or active exploitation has been identified at the time of analysis.

Fleet device management software versions prior to 4.81.1 contain a broken access control vulnerability in the host transfer API that allows authenticated team maintainers to transfer hosts from any team into their own team, circumventing team isolation boundaries and gaining full control over stolen hosts including root-level script execution capabilities. The vulnerability requires authenticated access (PR:L in CVSS vector) but presents high integrity impact due to the ability to execute privileged commands on managed endpoints. No public exploit code or active exploitation has been confirmed at time of analysis.

Fleet server memory exhaustion via unbounded request bodies allows unauthenticated denial-of-service against multiple HTTP endpoints. The vulnerability affects Fleet v4 (github.com/fleetdm/fleet/v4) and was responsibly disclosed by @fuzzztf. Attackers can exhaust available memory and force server restarts by sending oversized or repeated HTTP requests to unauthenticated endpoints lacking size limits. No public exploit identified at time of analysis, though the attack mechanism is straightforward given the CWE-770 resource allocation vulnerability class.

Fleet's password reset token invalidation logic fails to revoke previously issued tokens when a user changes their password, allowing attackers with a captured token to perform account takeover by resetting the password again within the token's 24-hour validity window. The vulnerability affects Fleet versions distributed via the Go package github.com/fleetdm/fleet/v4 and requires prior compromise of a valid password reset token to exploit, limiting real-world impact to scenarios where token interception has already occurred.

WWBN AVideo versions up to 26.0 expose all non-private video categories to unauthenticated remote attackers due to missing access control enforcement in the categories.json.php endpoint. The vulnerability combines two distinct flaws: complete bypass of group-based filtering when no user parameter is supplied, and a type confusion bug that substitutes the admin user's group memberships when a user parameter is present, allowing unauthorized disclosure of category metadata intended for restricted user groups. CVSS 5.3 reflects the information disclosure impact with no authentication required and low attack complexity; no public exploit code or active exploitation has been confirmed at time of analysis.

A proof-of-concept exists, though no confirmation of active exploitation in the wild has been reported.

Broken access control in Frigate 0.17.0 allows authenticated non-admin users to retrieve the complete raw configuration file via the `/api/config/raw` endpoint, exposing camera credentials, RTMP stream passwords, MQTT secrets, and proxy authentication tokens that are intentionally redacted from the standard `/api/config` API. The vulnerability stems from inconsistent authorization enforcement between `/api/config/raw_paths` (admin-only) and `/api/config/raw` (authenticated-user-accessible), introduced during an admin-by-default API refactor. Patch version 0.17.1 is available; publicly available exploit code exists but the vulnerability is not confirmed as actively exploited in the wild.

srvx's FastURL pathname parser on Node.js can be bypassed to circumvent route-based middleware (authentication guards, rate limiters) when absolute URIs with non-standard schemes are sent in raw HTTP requests. An attacker sending a crafted request like `GET file://hehe?/internal/run HTTP/1.1` can cause the router to match a different pathname than what downstream middleware sees after a deoptimization occurs, allowing access to protected endpoints. This affects srvx versions prior to 0.11.13, requires direct HTTP request capability (not browser-accessible), and has a CVSS score of 4.8 with medium complexity attack requirements. No public exploit identified at time of analysis.

Cilium Network Policy enforcement is bypassed for traffic from pods to L7 Services with local backends on the same node when Per-Endpoint Routing is enabled and BPF Host Routing is disabled, allowing authenticated local attackers to circumvent ingress network policies and access restricted services. This affects Cilium v1.19.0-v1.19.1, v1.18.0-v1.18.7, and all versions prior to v1.17.13, with the most common vulnerable deployment being Amazon EKS with Cilium ENI mode. Vendor-released patches are available (v1.19.2, v1.18.8, v1.17.14), and no public exploit code has been identified at the time of analysis.

EVerest charging software stack versions prior to 2026.02.0 allow EV operators to bypass remote stop commands issued by a Charging Station Management System (CSMS) by toggling the EV's Battery Control Box (BCB), causing the EVSE to return to PrepareCharging state and restart charging sessions. This circumvents billing, operational, and safety controls enforced by remote stop functionality. A proof-of-concept exists and the vulnerability has been patched in version 2026.02.0, though the attack requires physical proximity to the charging equipment (CVSS attack vector: Physical).

EVerest-core prior to version 2026.02.0 fails to properly terminate EV charging transactions during remote stop operations due to a delayed authorization response that incorrectly restores the authorized flag to true, allowing transactions to remain open even after a PowerOff event triggers stop_transaction(). This authentication bypass affects EV charging infrastructure and enables continued power delivery after an operator-initiated remote stop command. A proof-of-concept exists but no public confirmation of active exploitation has been identified.

EVerest EV charging software before version 2026.02.0 fails to properly stop charging transactions when authorization withdrawal occurs before the TransactionStarted event, allowing attackers with high privileges to bypass deauthorization through precise timing and maintain unauthorized charging sessions. The vulnerability stems from incomplete StopTransaction handling in the Charging state, affecting IoT and Everest Core deployments with no currently available patch.

Mattermost versions 11.2.x through 11.4.x fail to enforce view restrictions on group member endpoints, allowing authenticated guest users to enumerate user IDs beyond their authorized visibility scope. This authorization bypass requires valid credentials but enables attackers to discover internal user information through the group retrieval API. No patch is currently available for affected versions.

Session invalidation failure in HCL Aftermarket DPC versions up to 1.0.0 allows authenticated attackers to maintain active sessions after a password change, enabling persistent account takeover. An attacker who gains initial session access can continue to operate under a compromised account identity even after the victim resets their password, as the application fails to terminate pre-existing sessions upon credential modification. No public exploit code or active exploitation has been identified at time of analysis.

HCL Aftermarket DPC versions up to 1.0.0 are vulnerable to session fixation attacks that enable attackers to hijack user sessions and perform unauthorized transactions without requiring valid credentials. The vulnerability exploits improper session management to allow an attacker to force a victim to use a predetermined session identifier, then leverage that session for fraudulent activity. This is a network-accessible flaw requiring user interaction (e.g., clicking a malicious link) but no prior authentication. No public exploit code or active exploitation has been identified at the time of analysis.

HCL Aftermarket DPC version 1.0.0 enforces weak password policies that enable attackers to conduct brute-force attacks and guess user credentials, potentially gaining unauthorized account access with low confidentiality and availability impact. The vulnerability requires user interaction and high attack complexity to exploit, but affects unauthenticated threat actors over the network. No public exploit code or active exploitation has been identified at the time of analysis.

HCL Aftermarket DPC version 1.0.0 contains a Cross-Origin Resource Sharing (CORS) misconfiguration that permits authenticated attackers with low privileges to access sensitive user information and potentially perform unauthorized actions on behalf of legitimate users through browser-based attacks. The vulnerability requires user interaction (such as social engineering to visit a malicious webpage) and operates within a single security context, limiting its scope to confidentiality impact with no integrity or availability consequences. No public exploit code has been identified at the time of analysis, and the low CVSS score of 2.6 reflects the high attack complexity and limited practical exploitability despite the theoretical risk of data exposure.

Small HTTP Server 3.06.36 allows local attackers with low privileges to execute arbitrary code through an unquoted service path vulnerability in the http.exe service executable. By placing a malicious executable in a higher-priority directory along the unquoted path 'C:\Program Files (x86)\shttps_mg\http.exe service', attackers can achieve full system compromise with high confidentiality, integrity, and availability impact. No public exploit has been identified at time of analysis, and CISA SSVC framework indicates no current exploitation, though technical impact is rated as total.

Small HTTP Server 3.06.36 contains an unquoted service path vulnerability (CWE-428) allowing local authenticated attackers to execute arbitrary code with elevated privileges by placing malicious executables in higher-priority directories. Despite a CVSS 4.0 score of 8.7, real-world risk is significantly lower with only 0.02% EPSS probability (4th percentile) and no public exploit identified at time of analysis. INCIBE has reported this vulnerability with patches available from the vendor.

Vienna Assistant 1.2.542 on macOS allows local privilege escalation through an unauthenticated XPC service endpoint that accepts connections from any process. The vulnerable VSL privileged helper service exposes functions to write arbitrary files to any location and execute arbitrary binaries with any arguments, enabling a low-privileged local user to gain root access. A proof-of-concept exploit exists per SSVC assessment, with an EPSS score of 0.02% indicating low observed exploitation probability in the wild.

HiJiffy Chatbot contains an authorization bypass vulnerability in the /api/v1/webchat/message endpoint that allows unauthenticated attackers to download private messages from arbitrary users by manipulating the 'visitor' parameter. The vulnerability affects all versions of HiJiffy Chatbot (as indicated by the wildcard CPE) and has been reported by INCIBE. No public exploit code or active exploitation has been confirmed at the time of analysis.

An incorrect authorization vulnerability in HiJiffy Chatbot allows unauthenticated attackers to download private messages from arbitrary users by manipulating the 'ID' parameter in the '/api/v1/download/<ID>/' endpoint. This is a classic authorization bypass enabling unauthorized access to sensitive conversation data. No public exploit code or active exploitation has been identified at the time of analysis, though the vulnerability was reported by INCIBE and affects all versions of HiJiffy Chatbot. The exposure is direct and requires only network access to the affected API endpoint.

The Elementor Website Builder plugin for WordPress contains an authorization bypass vulnerability in the is_allowed_to_read_template() function that incorrectly permits authenticated users with contributor-level privileges to read private and draft template content. Attackers can exploit this through the 'get_template_data' action of the 'elementor_ajax' endpoint by supplying a 'template_id' parameter, resulting in exposure of sensitive template information. The vulnerability affects all versions up to and including 3.35.7 with a CVSS score of 4.3 (low-to-moderate severity) and requires low-complexity exploitation with authenticated access.

The FormLift for Infusionsoft Web Forms WordPress plugin contains a missing authorization vulnerability (CWE-862) that allows unauthenticated attackers to hijack the site's Infusionsoft OAuth connection. Affected versions through 7.5.21 fail to validate user authentication on critical OAuth handler methods, enabling attackers to intercept temporary OAuth credentials and inject arbitrary OAuth tokens and app domains via the update_option() function. This is a network-accessible, low-complexity vulnerability with no required privileges; while the CVSS score is moderate (5.3), the real-world impact is integrity compromise of the CRM integration layer, potentially affecting customer data flows and automation.

The Blog2Social plugin for WordPress contains an authorization flaw in the resetSocialMetaTags() function that allows authenticated attackers with Subscriber-level access to permanently delete all social media metadata from the site's post records. The vulnerability exists in all versions up to and including 8.8.2 and affects sites using the Blog2Social: Social Media Auto Post & Scheduler plugin, which is available via the WordPress plugin repository. Attackers can exploit this by crafting AJAX requests with a valid nonce that is broadly available due to the plugin granting the 'blog2social_access' capability to all user roles upon activation, resulting in complete data loss of social media scheduling information across all posts.

The Masteriyo LMS plugin for WordPress contains a critical privilege escalation vulnerability that allows authenticated users with Student-level access or higher to elevate their privileges to administrator level. All versions up to and including 2.1.6 are affected. The vulnerability is exploitable over the network with low attack complexity and requires no user interaction, resulting in a critical CVSS score of 9.8, though the CVSS vector indicates no authentication required (PR:N) which conflicts with the description stating Student-level access is needed.

Improper authentication in the password-protected share handler of Kalcaddle Kodbox 1.64 allows remote attackers to bypass access controls through manipulation of the authentication function, despite high attack complexity. Public exploit code exists for this vulnerability, and no patch is currently available from the vendor.
