When HTTP_PROXY, HTTPS_PROXY, or ALL_PROXY environment variables are present, attacker-influenced URLs can be routed through proxy behavior instead of pinned-destination routing, enabling access to internal targets reachable from the proxy environment.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:L/VA:L/SC:N/SI:N/SA:N","score":6.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L","score":7.6},"cwes":["CWE-918"],"references":["https://github.com/openclaw/openclaw/commit/345abf0b2e0f43b0f229e96f252ebf56f1e5549e","https://github.com/openclaw/openclaw/security/advisories/GHSA-8mvx-p2r9-r375","https://www.vulncheck.com/advisories/openclaw-dns-pinning-bypass-via-environment-proxy-configuration-in-web-fetch"],"products":["openclaw:openclaw"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-22181","score":0.00243,"percentile":0.15548,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-8mvx-p2r9-r375","url":"https://osv.dev/vulnerability/GHSA-8mvx-p2r9-r375","summary":"OpenClaw's web tools strict URL guard could lose DNS pinning when env proxy is configured","modified":"2026-03-19T18:47:06.272674Z","packages":[{"ecosystem":"npm","name":"openclaw","purl":"pkg:npm/openclaw","ranges":["<2026.3.2"],"fixed":["2026.3.2"]}]}],"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).
