{"id":"CVE-2026-32045","aliases":["GHSA-hff7-ccv5-52f8"],"url":"https://o3.security/vulnerability/CVE-2026-32045","summary":"OpenClaw < 2026.2.21 - Authentication Bypass in HTTP Gateway Routes via Tokenless Tailscale Auth","details":"### Summary\nWhen tokenless Tailscale auth is enabled, OpenClaw should only allow forwarded-header auth for Control UI websocket authentication on trusted hosts. In affected versions, that tokenless path could also be used by HTTP gateway auth call sites, which could bypass token/password requirements for HTTP routes in trusted-network deployments.\n\n### Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Affected range: `<= 2026.2.19-2` (latest published npm version as of February 21, 2026)\n- Patched in: planned `2026.2.21` release\n\n### Impact\nDeployments relying on token/password for HTTP gateway routes could be downgraded to tokenless behavior when Tailscale header auth is enabled. This weakens expected HTTP route authentication boundaries even in trusted-host network setups.\n\nPer SECURITY.md, this does not affect the recommended setup: keep the Gateway loopback-only (or otherwise within a trusted host/network boundary), use Tailscale serve/funnel for remote access, and keep tokenless Tailscale auth scoped to Control UI websocket login.\n\n### Fix\n- Added an explicit auth-surface gate (`allowTailscaleHeaderAuth`, default `false`) in gateway auth.\n- Enabled tokenless Tailscale header auth only for Control UI websocket authentication.\n- Kept HTTP gateway auth call sites on token/password auth paths.\n- Added regression coverage for HTTP-vs-websocket behavior and Tailscale header handling.\n\n### Fix Commit(s)\n- `356d61aacfa5b0f1d5830716ec59d70682a3e7b8`\n\n### Release Process Note\n`patched_versions` is pre-set to the planned next release (`2026.2.21`) so once npm release is published, this advisory can be published directly without further field edits.\n\nOpenClaw thanks @zpbrent for reporting.","published":"2026-03-21T00:42:19.737Z","modified":"2026-08-12T03:51:08.519036812Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.21"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/356d61aacfa5b0f1d5830716ec59d70682a3e7b8","label":"openclaw/openclaw@356d61a"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32045.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-hff7-ccv5-52f8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32045"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-authentication-bypass-in-http-gateway-routes-via-tokenless-tailscale-auth"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/356d61aacfa5b0f1d5830716ec59d70682a3e7b8"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:08.519036812Z"}}
