CVE-2026-54223

Estado: AplazadaAlta (8.6)—

UBB.threads is vulnerable to Path traversal, allowing attackers with privilege to edit templates to read and write any file on the application’s server that application has privileges to, what results in Remote Code Execution.  Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 7.7.5 but may also affect other versions.

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.

Acceso remoto de red con privilegios elevados (PR:H) contra servicio remoto (UBB.threads). Path traversal permite leer archivos (T1005) y escribir código malicioso para RCE (T1059). CWE-22 + VC:H/VI:H confirma.

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.
