OpenClaw: fetch-guard forwards custom authorization headers across cross-origin redirects
OpenClaw's fetchWithSsrFGuard(...) followed cross-origin redirects while preserving arbitrary caller-supplied headers except for a narrow denylist (Authorization, Proxy-Authorization, Cookie, Cookie2). This allowed custom authorization headers such as X-Api-Key, Private-Token, and similar sensitive headers to be forwarded to a different origin after a redirect.
The fix switches cross-origin redirect handling from a narrow sensitive-header denylist to a safe-header allowlist, so only benign headers such as content negotiation and cache validators survive an origin change.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
<= 2026.3.2 - Patched version:
2026.3.7 - Latest published npm version at patch time:
2026.3.2
Impact
A remote service that could trigger a redirect across origins could receive custom authorization credentials attached by OpenClaw callers. This can expose API keys, bearer-style custom headers, or private token headers intended only for the original destination.
