{"id":"CVE-2026-26324","aliases":["GHSA-jrvc-8ff5-2f9f"],"url":"https://o3.security/vulnerability/CVE-2026-26324","summary":"OpenClaw has a SSRF guard bypass via full-form IPv4-mapped IPv6 (loopback / metadata reachable)","details":"### Summary\n\nOpenClaw's SSRF protection could be bypassed using full-form IPv4-mapped IPv6 literals such as `0:0:0:0:0:ffff:7f00:1` (which is `127.0.0.1`). This could allow requests that should be blocked (loopback / private network / link-local metadata) to pass the SSRF guard.\n\n- Vulnerable component: SSRF guard (`src/infra/net/ssrf.ts`)\n- Issue type: SSRF protection bypass\n\n### Affected Packages / Versions\n\n- Package: `openclaw` (npm)\n- Vulnerable: `<= 2026.2.13`\n- Patched: `>= 2026.2.14` (planned next release)\n\n### Details\n\nThe SSRF guard's IP classification did not consistently detect private IPv4 addresses when they were embedded in IPv6 using full-form IPv4-mapped IPv6 notation. As a result, inputs like `0:0:0:0:0:ffff:7f00:1` could bypass loopback/private network blocking.\n\n### Fix Commit(s)\n\n- `c0c0e0f9aecb913e738742f73e091f2f72d39a19`\n\n### Release Process Note\n\nThis advisory is kept in draft state with the patched version set to the planned next release. Once `openclaw@2026.2.14` is published to npm, the only remaining step should be to publish this advisory.\n\nThanks @yueyueL for reporting.","published":"2026-02-19T22:49:24.293Z","modified":"2026-10-28T02:31:12.696050953Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":{"score":0.00391,"percentile":0.31918,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.14"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/c0c0e0f9aecb913e738742f73e091f2f72d39a19","label":"openclaw/openclaw@c0c0e0f"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/releases/tag/v2026.2.14"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26324.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-jrvc-8ff5-2f9f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-26324"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/c0c0e0f9aecb913e738742f73e091f2f72d39a19"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:31:12.696050953Z"}}
