CVE-2026-32913: 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.

Verification

• pnpm check passed
• pnpm test:fast passed
• Focused redirect regression tests passed
• pnpm exec vitest run --config vitest.gateway.config.ts still has unrelated current-main failures in src/gateway/server-channels.test.ts and src/gateway/server-methods/agents-mutate.test.ts

Release Process Note

npm 2026.3.7 was published on March 8, 2026. This advisory is fixed in the released package.
