CVE-2026-40045

Estado: AnalizadaMedia (5.9)—

OpenClaw before 2026.4.2 accepts non-loopback cleartext ws:// gateway endpoints and transmits stored gateway credentials over unencrypted connections. Attackers can forge discovery results or craft setup codes to redirect clients to malicious endpoints, disclosing plaintext gateway credentials.

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).
