CVE-2026-82866

Estado: AplazadaAlta (8.9)—

@pdfme/common before 5.5.10 contains a server-side request forgery vulnerability in the getB64BasePdf function that fetches arbitrary URLs without validation when basePdf is attacker-controlled. Attackers who control the basePdf template field can force servers or clients to make requests to internal endpoints, enabling metadata exfiltration, network reconnaissance, and blind request forgery attacks.

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 en función getB64BasePdf con acceso a red sin autenticación (AV:N/PR:N). Impactos: proxy/SSRF (T1090) y exfiltración de metadata/datos internos (T1005) confirmados en descripción.

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.
