CVE-2026-71509

Estado: AplazadaAlta (7.1)—

Dolibarr before 24.0.0 contains an improper authorization vulnerability in the expense report REST API update endpoint that allows authenticated attackers with expense-creation rights to bypass the approval workflow by directly setting approval status and approver identity fields. Attackers can manipulate workflow state fields through the REST API to advance expense reports to approved or closed status without possessing the dedicated approval right, while also creating forensic inconsistencies in audit records due to missing approval timestamps.

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.

Autenticado remoto (PR:L, VI:H) explota API REST para elevar privilegios de aprobación. Manipula campos de workflow para obtener permisos no autorizados y corrompe registros de auditoría.

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.
