{"id":"GHSA-vqx6-6j84-2794","summary":"Duplicate Advisory: Hostname checks could treat trailing-dot hosts inconsistently","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-gxg4-2rrr-jhc7. This link is maintained to preserve external references.\n\n## Original Description\nOpenClaw before 2026.5.26 contains a hostname validation vulnerability allowing attackers to bypass blocklist comparisons using trailing-dot notation in model or workspace-derived URLs. Attackers can exploit inconsistent hostname checks to reach destinations that operators intended to block through hostname policies.","modified":"2026-06-18T20:15:17.327175917Z","published":"2026-06-16T21:31:59Z","withdrawn":"2026-06-18T20:11:21Z","database_specific":{"cwe_ids":["CWE-918"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-06-18T20:11:21Z","nvd_published_at":"2026-06-16T19:17:03Z"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-gxg4-2rrr-jhc7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53859"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-hostname-validation-bypass-via-trailing-dot-inconsistency"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"2026.5.22"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-vqx6-6j84-2794/GHSA-vqx6-6j84-2794.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
