Original Description
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.
