CVE-2026-85179

Estado: AplazadaAlta (8.4)—

Label Studio through 1.23.0 fails to validate webhook URLs, allowing authenticated users to dispatch requests to internal services including RFC 1918 addresses and cloud metadata endpoints. Attackers can create webhooks targeting private networks and exfiltrate annotation data by enabling payload transmission in outbound requests.

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:L sin UI permite a usuario autenticado explotar servicio remoto (webhook SSRF). Exfiltra datos de anotación mediante SSRF a servicios internos y metadata endpoints.

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.
