CVE-2026-40037

Estado: AnalizadaAlta (7.1)—

OpenClaw before 2026.3.31 (patched in 2026.4.8) contains a request body replay vulnerability in fetchWithSsrFGuard that allows unsafe request bodies to be resent across cross-origin redirects. Attackers can exploit this by triggering redirects to exfiltrate sensitive request data or headers to unintended origins.

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
