Remote attackers with network access to the hooks endpoint can exploit timing side-channels across multiple requests to gradually determine the authentication token.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.2},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-208"],"references":["https://github.com/openclaw/openclaw/commit/113ebfd6a23c4beb8a575d48f7482593254506ec","https://github.com/openclaw/openclaw/security/advisories/GHSA-jmm5-fvh5-gf4p","https://www.vulncheck.com/advisories/openclaw-timing-attack-in-hooks-token-authentication"],"products":["openclaw:openclaw"],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-28464","score":0.00449,"percentile":0.3903,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-jmm5-fvh5-gf4p","url":"https://osv.dev/vulnerability/GHSA-jmm5-fvh5-gf4p","summary":"OpenClaw has non-constant-time token comparison in hooks authentication","modified":"2026-03-06T01:16:33.635775Z","packages":[{"ecosystem":"npm","name":"openclaw","purl":"pkg:npm/openclaw","ranges":["<2026.2.12"],"fixed":["2026.2.12"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
