This page collects WhisperX intelligence signals tagged #Authentication Bypass. It is designed for humans, search engines, and AI agents: each item links to a canonical source-backed record with sector, source, timestamp, credibility, and exportable structured data.
A critical security vulnerability has been identified in a production codebase, where hardcoded JWT secret fallbacks could allow attackers to forge authentication tokens. The flaw, designated SEC-01, is a P0-level issue requiring immediate remediation before any future deployment. The core problem resides in the config...
A critical vulnerability in Apache ZooKeeper's ZKTrustManager can allow attackers to impersonate trusted servers or clients. The flaw, tracked as CVE-2026-24281, stems from a fallback mechanism in hostname verification. When validation of an IP address in a certificate's Subject Alternative Name (IP SAN) fails, the sys...
A critical detection rule for a Budibase authentication bypass vulnerability has been published on GitHub. The rule, designed for security monitoring systems, specifically targets CVE-2026-31816, which allows attackers to gain unauthenticated access to protected endpoints. The exploit hinges on a flawed authorization m...
A critical testing gap has been identified within the `wast mcpscan` security subsystem. The two highest-severity vulnerability check modules—responsible for detecting Server-Side Request Forgery (SSRF) and authentication bypass flaws—currently operate with zero unit test coverage. This means changes to the `SSRFChecke...
A critical security vulnerability allows users with disabled or banned LDAP accounts to retain full SSH access to artifact repositories indefinitely. The flaw exists because SSH authentication paths fail to check user account status, creating a dangerous bypass of standard access controls. While web and JWT authenticat...
A critical security vulnerability in Keycloak, the widely-used open-source identity and access management solution, has been disclosed. The flaw, tracked as CVE-2026-4282, resides in the SingleUseObjectProvider—a global key-value store that lacks proper type and namespace isolation. This architectural weakness creates ...
A critical security flaw allows attackers to forge valid administrative access tokens by exploiting a JWT algorithm confusion vulnerability. The server, which expects tokens signed with the RS256 algorithm, fails to enforce this, accepting tokens that declare the HS256 algorithm instead. This enables an attacker to sig...
A critical security flaw allows attackers to forge valid authentication tokens and bypass JWT security entirely by exploiting a misconfigured server that accepts the 'none' algorithm. The vulnerability, confirmed with 90% confidence and rated a CVSS 9.8, was discovered on the `/admin/login` endpoint, where the server i...
A critical SQL injection vulnerability in a production authentication system has been actively exploited, allowing attackers to bypass login security. The flaw, located in the `/login` endpoint, was detected through production log analysis, confirming that an attacker successfully authenticated as an administrative use...
ExtensionShield's core cloud authentication mechanism is built on a known-vulnerable and unmaintained dependency, exposing the platform to potential identity forgery and complete authentication bypass. The project's `pyproject.toml` explicitly depends on `python-jose[cryptography]>=3.3.0`, a library with documented cri...
A critical security misconfiguration in a Next.js application's middleware exposes all new API routes to unauthorized access by default. The vulnerability, rated MEDIUM (CVSS 5.9), stems from a matcher pattern in `proxy.ts` that explicitly excludes all `/api/*` paths from authentication checks. While a specific cron en...
A critical security flaw in the Strawberry GraphQL framework allows attackers to bypass authentication on WebSocket subscription endpoints. The vulnerability, tracked as CVE-2026-35523, is present in all versions up to 0.312.2. The core failure lies in the legacy `graphql-ws` subprotocol handler, which processes subscr...
A critical authentication vulnerability has been identified in two core API models, allowing attackers to potentially impersonate any user. The flaw stems from a dangerous design pattern where the API accepts both a cryptographically verified JWT token and a separate, client-submitted user ID parameter (`asf_uid`). Thi...
A critical SQL injection vulnerability (CWE-89) was discovered in the core authentication function for a healthcare provider system, posing a severe risk of unauthorized access and data manipulation. The flaw, rated a CVSS 3.1 score of 9.8, resided in the `authenticate_user` function within `src/auth/login.py`. Attacke...
A critical security vulnerability has been exposed in a JWT authentication middleware, allowing attackers to bypass authentication entirely. The flaw resides in the `decodeToken` function within `packages/api/src/middleware/auth.middleware.ts`, which decodes and validates a JWT's payload but crucially fails to verify t...
A critical SQL injection vulnerability in a healthcare provider authentication system allowed attackers to bypass login entirely and execute arbitrary SQL commands, potentially exposing all patient records across all facilities. The flaw, rated a maximum severity 9.8 on the CVSS scale, was found in the `authenticate_us...
A newly disclosed vulnerability in Apache Tomcat allows attackers to bypass critical security constraints, potentially gaining unauthorized access to protected server resources. The flaw, tracked as CVE-2025-49125 (GHSA-wc4r-xq3c-5cf3), is an authentication bypass issue that stems from how the software handles PreResou...
A critical vulnerability in the widely-used Python authentication library Authlib allows attackers to forge cryptographically valid JWT tokens, completely bypassing server authentication and authorization. The flaw, tracked as CVE-2026-27962, resides in the library's JWS (JSON Web Signature) implementation. When `key=N...
A critical security flaw in Mercato's API router defaulted routes to public access when their metadata was missing or undefined, leaving at least four key sales endpoints unprotected. The vulnerability, discovered in the `checkAuthorization` function, meant that routes for `shipments`, `order-adjustments`, `quote-adjus...
A critical logic flaw in Cryptomator Hub's OAuth flow allows attackers to bypass a previous security fix and force a downgrade to plaintext HTTP, exposing user access tokens. The vulnerability, tracked as CVE-2026-33472, resides in the `CheckHostTrustController.getAuthority()` method of version 1.19.1. This method inco...
