CVE-2026-71504

Estado: AplazadaAlta (8.6)—

Dolibarr before 24.0.0 contains an improper authorization vulnerability in the Members REST API that allows attackers with only member-creation rights to reset the password of any user account, including the system administrator, without verifying password-change permissions. Attackers can supply an arbitrary user account identifier and new password in the request body to overwrite credentials and immediately lock out the legitimate account holder.

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.

Acceso de red con privilegios (PR:L) en API REST remota; impacto: cambio de credenciales de administrador sin verificación de permisos (CWE-862), permitiendo takeover de cuenta (T1078) y modificación de cuentas (T1098.002).

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.
