CVE-2026-4982

Estado: Pendiente de análisisAlta (7.3)—

A user with permission "update world" in any Venueless world is able to exfiltrate chat messages from direct messages or channels in other worlds on the same server due to a bug in the reporting feature.

The exploitability is limited by the fact that the attacker needs to know the internal channel UUID of the chat channel, which is unlikely to be obtained by an outside attacker, especially for direct messages.

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.
