CVE-2026-86746

Estado: AnalizadaAlta (7.4)—

Snipe-IT before 8.7.0 contains an authorization bypass vulnerability in Livewire components that enforce authorization only at the route level, not within component lifecycle methods. Attackers with a valid authenticated session can replay signed component snapshots via POST /livewire/update to invoke protected methods and escalate privileges, including creating OAuth clients, minting personal access tokens, and accessing sensitive admin data.

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.

Requiere sesión autenticada válida (PR:L) e interacción del usuario (UI:P) para reproducir snapshots firmados. Escalada de privilegios mediante bypass de autorización en métodos de componentes, creación de clientes OAuth y tokens de acceso.

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.
