Remote attackers can access relay HTTP endpoints off-host to leak service presence and port information, or conduct denial-of-service and brute-force attacks against the relay token header.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N","score":6.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","score":9.1},"cwes":["CWE-1327"],"references":["https://github.com/openclaw/openclaw/commit/8d75a496bf5aaab1755c56cf48502d967c75a1d0","https://github.com/openclaw/openclaw/commit/a1e89afcc19efd641c02b24d66d689f181ae2b5c","https://github.com/openclaw/openclaw/security/advisories/GHSA-qw99-grcx-4pvm","https://www.vulncheck.com/advisories/openclaw-unintended-public-binding-of-chrome-extension-relay-via-wildcard-cdpurl"],"products":["openclaw:openclaw"],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-28395","score":0.0046,"percentile":0.39915,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-qw99-grcx-4pvm","url":"https://osv.dev/vulnerability/GHSA-qw99-grcx-4pvm","summary":"OpenClaw's Chrome extension relay binds publicly due to wildcard treated as loopback","modified":"2026-03-06T01:01:26.322453Z","packages":[{"ecosystem":"npm","name":"openclaw","purl":"pkg:npm/openclaw","ranges":[">=2026.1.14-1 <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).
