CVE-2026-25660

Estado: AnalizadaCrítica (9.3)—

CodeChecker is an analyzer tooling, defect database and viewer extension for the Clang Static Analyzer and Clang Tidy. Authentication bypass occurs when the URL ends with Authentication with certain function calls.  This bypass allows assigning arbitrary permission to any user existing in CodeChecker.

This issue affects CodeChecker: through 6.27.3.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:N, PR:N, UI:N indica explotación remota sin autenticación (T1190). Auth bypass + asignación arbitraria de permisos permite acceso con privilegios elevados (T1078) y manipulación de cuentas (T1098).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
