Remote attackers with network access to the hooks endpoint can exploit timing side-channels across multiple requests to gradually recover the authentication token.","published":"2026-03-05T21:59:50.631Z","modified":"2026-08-07T11:50:56.248003390Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.13"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/113ebfd6a23c4beb8a575d48f7482593254506ec","label":"openclaw/openclaw@113ebfd"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/28xxx/CVE-2026-28475.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-47q7-97xp-m272"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-28475"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-timing-attack-via-hook-token-comparison"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/113ebfd6a23c4beb8a575d48f7482593254506ec"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:56.248003390Z"}}
