{"id":"GHSA-4rqq-w8v4-7p47","summary":"OpenClaw has incomplete IPv4 special-use SSRF blocking in web fetch guard","details":"### Summary\n`isPrivateIpv4()` in bundled SSRF guard code missed several IPv4 special-use/non-global ranges, so `web_fetch` could allow targets that should be blocked by SSRF policy.\n\n### Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Latest published affected version: `2026.2.21-2` (published 2026-02-21)\n- Structured vulnerable range: `\u003c= 2026.2.21-2`\n- Planned patched version (pre-set): `\u003e= 2026.2.22`\n\n### Impact\nLow severity. Exploitation requires network reachability to the relevant special-use ranges and a request path that reaches `web_fetch` URL fetching.\n\n### Technical Details\nAffected releases used narrow IPv4 private-range checks that omitted multiple RFC special-use/non-global ranges. This allowed requests such as `http://198.18.0.1/...` through SSRF validation in affected releases. Follow-up hardening consolidates local-host/tailnet range checks so gateway/browser/tailnet paths share one canonical IP classification flow.\n\n### Fix Commit(s)\n- `71bd15bb4294d3d1b54386064d69cd0f5f731bd8`\n- `44dfbd23df453e51b71ef79a148c28c53e89168c`\n- `333fbb86347998526dd514290adfd5f727caa6d9`\n- `f14ebd743cfc73f667fae80af70043d0ab1f88bd`\n\nOpenClaw thanks @princeeismond-dot for reporting.","aliases":["CVE-2026-32019"],"modified":"2026-05-05T15:56:08.344024Z","published":"2026-03-04T19:03:45Z","database_specific":{"cwe_ids":["CWE-918"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-03-04T19:03:45Z","nvd_published_at":"2026-03-19T22:16:35Z"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-4rqq-w8v4-7p47"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32019"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/333fbb86347998526dd514290adfd5f727caa6d9"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/44dfbd23df453e51b71ef79a148c28c53e89168c"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/71bd15bb4294d3d1b54386064d69cd0f5f731bd8"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/f14ebd743cfc73f667fae80af70043d0ab1f88bd"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-incomplete-ipv4-special-use-range-blocking-in-ssrf-guard"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.2.22"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-4rqq-w8v4-7p47/GHSA-4rqq-w8v4-7p47.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
