CVE-2026-53815

Status: AnalyzedHigh (7.1)—

OpenClaw before 2026.5.19 contains an authorization bypass vulnerability in message read actions that skips channel allowlist checks. Lower-trust callers can request messages from channels not intended for them by exploiting insufficient validation in the affected feature, potentially exposing sensitive channel messages.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

AV:N/PR:L sin UI indica acceso remoto con privilegios, típico de T1210. La falta de validación de autorización (CWE-862) permite leer mensajes no autorizados (T1005) y potencialmente asumir identidades (T1078).

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
