CVE-2026-96589

Estado: Pendiente de análisisMedia (4.3)—

When a private repository is transferred to a user who lacks access, Gitea grants that recipient temporary read access as a collaborator so they can review the repository. Rejecting or cancelling the transfer did not revoke this collaboration, so the named recipient kept persistent read access to the private repository, including its code, issues, pull requests and wiki, and could clone it. The repository owner was not notified. Transfer-granted access is now removed while collaborations that existed before the transfer are preserved.

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 remoto (AV:N, PR:L) a servicio de repositorio Gitea; impacto: persistencia de acceso de cuenta (T1078.002) y lectura de datos privados (código, issues, PRs, wiki) tras rechazar transferencia.

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.
