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 allows any unauthenticated user to download all files uploaded to the system. The file download endpoint `/api/files/` lacks the mandatory authentication middleware, creating a direct path for anonymous data access. This authentication bypass stands in stark contrast to all other file ...
A critical authentication bypass vulnerability has been confirmed in the API Gateway middleware, allowing any request with a simple header to gain full administrative privileges on all non-production environments. The code, found in the auth middleware, contains a development-only path that checks for an `x-dev-user-id...
A critical security vulnerability in the widely used pac4j-jwt library allows attackers to forge authentication tokens and bypass signature verification entirely. Designated CVE-2026-29000, the flaw resides in the JwtAuthenticator component when processing encrypted JWTs. An attacker in possession of the server's RSA p...
A medium-severity authentication flaw in the `checkInviteAutoVerify` Cloud Function allows an invite document to grant `emailVerified: true` status on every future login attempt, including from different user accounts sharing the same email address. The vulnerability, documented in GitHub issue SEC-105, affects the Fir...
A critical security vulnerability has been identified in Kailash's API Gateway middleware component, where a hardcoded default JWT signing key is embedded directly in publicly accessible open-source code. The finding, cataloged as F-C-35 during the Wave 5 portfolio specification audit, exposes a signing key measuring j...
A critical security flaw in the Orion-Web platform left an LLM-powered tool generation endpoint completely unauthenticated, exposing systems to arbitrary shell command execution. The vulnerability, tracked as SOC 2 corrective action CR-005, allowed attackers to craft malicious tool descriptions that the LLM would trans...
A critical authentication bypass vulnerability has been identified in the `flag_suspicious` function within the fraud-prevention module of a Soroban smart contract deployment. The flaw, documented in `contracts/fraud-prevention/src/lib.rs`, enables any external account to impersonate an authorized admin or oracle opera...
A medium-severity vulnerability in a chat application backend exposes its authentication layer to issuer validation bypass. The PyJWT token verification in `src/chat-app/backend/app/security.py` (lines 81–93) explicitly disables the library's built-in `iss` claim verification by passing `options={"verify_iss": False}` ...
A medium-severity authentication bypass has been identified in the ingest service's software-inventory RPC, where the handler explicitly accepts expired agent JWTs and fails to bind token identity to the mTLS client-certificate identity already available within the stream context. The vulnerability weakens the intended...
A critical security vulnerability in `backend/server.js` permits unauthenticated access to backend systems when the `API_KEY` environment variable is not configured. The code implements authentication as an optional feature rather than a mandatory requirement, creating a default-allow posture that contradicts secure-by...
A critical authentication vulnerability in the backend identity layer allows any process or caller reaching the local interface to silently mint full administrative tokens. The flaw, present in `backend/identity.py:140-178`, stems from the `require_principal()` function trusting `request.client.host` without verifying ...
A critical security flaw has been identified in the `/api/booking/create` endpoint of miconsu.app, leaving the booking system entirely unprotected. Security researchers note the endpoint lacks any session verification, allowing anonymous users to submit booking requests without authentication. The vulnerability permits...
Security analysis of the LLM Wiki web application backend has identified a critical authentication bypass vulnerability in `AuthController.login()`. The method accepts any non-empty password for existing user accounts, effectively bypassing credential verification entirely. The flaw was discovered in `backend/llm-wiki-...
Security researchers are tracking a cluster of critical vulnerabilities under active exploitation, with at least two vulnerabilities marked as critical severity showing evidence of real-world attacks. The most urgent involves a remote code execution flaw in Weaver E-cology, a widely deployed enterprise collaboration pl...
A critical authentication bypass vulnerability has been identified in the Model Context Protocol (MCP) service implementation within Apache Superset, allowing federated attackers to authenticate as any user—including administrative accounts—by exploiting how JWT claims are resolved during login. The flaw resides in `s...
A severe authentication flaw has been identified in sovity dataspace-portal, affecting versions 2.1.1 through 7.3.1. Tracked as CVE-2026-42160, the vulnerability allows attackers to bypass backend security controls by exploiting accounts in a "PENDING" state. Security researchers at OffSeq's threat intelligence platfor...
A high-severity authentication bypass vulnerability has been identified in expensetracker-1, stemming from the application's use of the jjwt (Java JWT) library at version 0.9.1. The vulnerability, tracked as CVE-2022-21449, allows attackers to forge valid JWT tokens with empty signatures, effectively bypassing authenti...
A security researcher operating in phishing assessment engagements reports a troubling pattern: passkeys, widely promoted as phishing-resistant authentication, can be defeated with reliable regularity using a specific class of relay and injection techniques. The researcher, who conducts these assessments professionally...
A critical vulnerability in cPanel and WebHost Manager (WHM) designated CVE-2026-41940 is under active exploitation by a threat actor identified as Mr_Rot13, who is deploying a backdoor named Filemanager on compromised servers. The flaw enables authentication bypass, granting remote attackers elevated control over web ...
A critical authentication bypass vulnerability has been exposed in SOFortress CoPilot, stemming from the use of a publicly known secret for signing JSON Web Tokens (JWTs). The flaw, catalogued as CVE-2026-42869, enables attackers to forge admin-scoped JWTs and potentially gain full control over the affected security op...
