CVE-2026-81826

Estado: AplazadaCrítica (9.1)—

Affected versions of Flowintel do not revoke existing authenticated sessions when a user’s password is changed.

This means that if an attacker already possesses a valid session—for example, from prior access or a stolen session token—the victim changing their password does not terminate that attacker’s access. The session remains usable until it expires naturally. The upstream commit describes this directly as:

“session keeps working until it expires.”

The fix detects password changes and explicitly invokes _invalidate_user_sessions(user.id) after the database update. This is applied in both edit_user_core() and admin_edit_user_core().

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 permite acceso remoto sin privilegios a sesiones robadas. El atacante mantiene acceso aunque la víctima cambie contraseña (CWE-384: session fixation).

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.
