CVE-2026-34746

Estado: AnalizadaAlta (7.7)—

Payload is a free and open source headless content management system. Prior to version 3.79.1, an authenticated Server-Side Request Forgery (SSRF) vulnerability exists in the upload functionality. Authenticated users with create or update access to an upload-enabled collection could cause the server to make outbound HTTP requests to arbitrary URLs. This issue has been patched in version 3.79.1.

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.

SSRF autenticado (PR:L) en funcionalidad de upload permite al atacante instruir al servidor para realizar solicitudes HTTP arbitrarias (T1090), potencialmente accediendo a recursos internos o exfiltrando datos. CWE-918 confirma SSRF.

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.
