In affected versions, a retry endpoint URL chosen by lower-trust input could pass validation by using a hostname prefix that resembled a trusted host.\n\nThis advisory is scoped to the named feature and configuration. It does not change OpenClaw's trusted-operator model: authenticated Gateway operators, installed plugins, and intentional local execution surfaces remain trusted unless a separate policy, approval, allowlist, sandbox, or auth boundary is crossed.\n\n### Impact\n\nWhen the affected feature is enabled and reachable, this could send authentication material to an endpoint outside the intended trust target. Practical impact depends on the operator's configuration and whether lower-trust input can reach that path.\n\n### Patched Versions\n\nThe first stable patched version is `2026.5.7`.\n\n### Mitigations\n\npin retry endpoints to exact trusted origins until patched. As general hardening, keep channel and tool allowlists narrow, avoid sharing one Gateway between mutually untrusted users, and disable the affected feature when it is not needed.","state":0,"publishedAt":"2026-07-02T17:22:11+00:00","modifiedAt":"2026-07-08T08:27:03.3797154+00:00","affected":[{"ecosystem":"npm","name":"openclaw","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"2026.5.7"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/openclaw/openclaw/security/advisories/GHSA-77q5-rr5v-x43q","https://github.com/openclaw/openclaw"],"sourceUrl":"https://github.com/advisories/GHSA-77q5-rr5v-x43q","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-77q5-rr5v-x43q","identifiers":["GHSA-77q5-rr5v-x43q","CVE-2026-53839"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
