CVE-2026-104440

Estado: AplazadaMedia (6.9)—

YesWiki before 4.6.7 contains a blind server-side request forgery vulnerability that allows unauthenticated attackers to make arbitrary server-side requests via the idtypeannonce parameter of /api/entries/bazarlist. Because isValidURL() always returns true, attackers can supply internal URLs fetched by curl in loadURLContent() to probe internal networks and reach internal services or metadata endpoints.

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 sin autenticación en parámetro de API de red pública (AV:N, PR:N, UI:N). CWE-918 confirma SSRF; curl/loadURLContent permite proxy y acceso a servicios internos y metadatos.

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.
