Attackers can inject malicious X-Crabbox-Owner and X-Crabbox-Org headers in requests authenticated with a shared token to bypass authorization checks and access owner/org-scoped lease operations belonging to victim accounts.","state":0,"publishedAt":"2026-05-14T21:30:43+00:00","modifiedAt":"2026-06-25T18:56:07.7618061+00:00","affected":[{"ecosystem":"Go","name":"github.com/openclaw/crabbox","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"0.12.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":null,"severity":null},{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://nvd.nist.gov/vuln/detail/CVE-2026-8621","https://github.com/openclaw/crabbox/pull/70","https://github.com/openclaw/crabbox/commit/b657323f1d1c954cefc8444571fa6c45a8896e7f","https://github.com/openclaw/crabbox","https://github.com/openclaw/crabbox/releases/tag/v0.12.0","https://www.vulncheck.com/advisories/crabbox-authentication-bypass-via-header-spoofing"],"sourceUrl":"https://github.com/advisories/GHSA-4g9m-rffv-h6wq","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-4g9m-rffv-h6wq","identifiers":["GHSA-4g9m-rffv-h6wq","CVE-2026-8621","GO-2026-5120"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
