Description

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.
