CVE-2026-55516
Snipe-IT is an IT asset/license management system. Prior to 8.6.2, PATCH or PUT /api/v1/maintenances/{maintenance_id} checks access to the current maintenance record and asset but then fills attacker-controlled fields including asset_id without re-authorizing the newly supplied asset, allowing an authorized user to move a maintenance record onto an asset outside their company scope. This issue is fixed in version 8.6.2.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:N
- Puntuación base: 7.7
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.38%
- Percentil entre todas las CVEs puntuadas: 29
- Fecha de la puntuación: 6/10/2026
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).

Vulnerabilidad de falta de reautorización (CWE-639) en API REST requiere PR:L (usuario autenticado remoto). PATCH/PUT sin revisar autorización del nuevo asset permite manipular registros de mantenimiento fuera de scope: modificación de datos (T1565.001) y secuestro de activos (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.
