fast-uri is a URI parser for Node.js. It canonicalizes a host to its ASCII form only when the input carries an explicit scheme, so a scheme-relative reference such as a host preceded by two slashes is returned with its host verbatim and no error set. As a result fast-uri's own entry points disagree with each other: parse, resolve, normalize, and equal can yield different hosts for the same input d…

ClaudeHookBridge versiones anteriores a 5.15.1 contiene una falla que trunca las cadenas de destino a 500 caracteres durante la evaluación de reglas de denegación (denyPatterns), mientras que Claude Code ejecuta el comando completo sin truncamiento. Un atacante puede insertar contenido malicioso después del byte 500 en campos Bash para eludir listas de bloqueo y ejecutar comandos arbitrarios. Esto afecta infraestructuras que integran este componente con sistemas de IA, siendo alta en entornos de CI/CD y automatización en la región.

Network-AI versiones anteriores a 5.15.1 contiene una vulnerabilidad que permite a atacantes evadir controles de seguridad mediante comandos entrecomillados. La vulnerabilidad radica en que SandboxPolicy valida strings de comandos preservando comillas, mientras que el ejecutor elimina comillas antes de ejecutar, permitiendo que comandos bloqueados se ejecuten exitosamente. Esto afecta crícticamente a empresas en LATAM que utilizan esta plataforma para automatización de infraestructura.

@cedar-policy/authorization-for-expressjs is an open-source Express.js middleware that integrates Cedar authorization into Express applications by mapping HTTP requests to Cedar actions and evaluating authorization policies before allowing requests to proceed. Versions prior to 0.3.0 have an issue where, under certain circumstances, the middleware matches incoming requests against Cedar action map…

@fastify/static before version 10.1.3 contains an incomplete fix for a previous route guard bypass. The static file handler rejected only parent directory segments, but it did not canonicalize dot segments, duplicate slashes, encoded dots, or backslashes before route matching and before delegating to the send layer. As a result, an unauthenticated attacker could request a file protected by a route…

Guzzle is an extensible PHP HTTP client. Prior to 7.15.2 and 8.0.1, Guzzle gives a transport the request URI as text and supplies the Host header separately. The cURL handlers set CURLOPT_URL to the URI exactly as written and push that Host into CURLOPT_HTTPHEADER; StreamHandler does the same through fopen(). libcurl then parses the authority itself, percent-decoding it and, on an IDN-capable buil…

fast-uri before 4.1.2, 3.1.5, and 2.4.4 requires a literal double forward slash to recognize a URI authority, so a reference that uses a backslash based introducer in place of it (backslash backslash, forward slash backslash, or backslash forward slash) is parsed with no authority and folds into the path. Node's native WHATWG URL parser instead treats a backslash as interchangeable with a forward …

V through 0.5.2, fixed in commit 85859f0, contains a server-side request forgery (SSRF) bypass vulnerability that allows attackers to circumvent host-based allowlists by exploiting a parser differential between net.urllib and net.http. Attackers can craft a URL containing a backslash in the authority section such that net.urllib.parse() extracts the trusted host for allowlist validation while net.…

A flaw was found in openshift/oauth-proxy. The proxy sets authenticated identity headers using only dash-variant keys (X-Forwarded-User) but does not strip underscore-variant keys (X_Forwarded_User) from incoming requests. WSGI and PHP frameworks normalize both variants to the same variable, allowing an authenticated low-privilege user to smuggle a forged identity that may override the legitimate …
