CVE-2026-32913Network attack vector

Credential exposure via cross-origin redirect header forwarding

Published Mar 23, 2026 · Updated Mar 23, 2026

Credential exposure in OpenClaw before 2026.3.7 allows remote attackers to obtain custom authorization headers through cross-origin redirects. fetchWithSsrFGuard preserves arbitrary caller-supplied headers across origin changes because it strips only Authorization, Proxy-Authorization, Cookie, and Cookie2. An attacker-controlled service must cause a redirect to another origin, which exposes API keys or private tokens intended only for the original destination.
