{"id":"GHSA-8cp7-rp8r-mg77","aliases":[],"url":"https://o3.security/vulnerability/GHSA-8cp7-rp8r-mg77","summary":"OpenClaw has SSRF guard bypass via IPv6 transition over ISATAP","details":"## Summary\nOpenClaw's SSRF hostname/IP guard did not detect ISATAP embedded IPv4 addresses (`...:5efe:w.x.y.z`). A crafted URL containing an ISATAP IPv6 literal could embed a private IPv4 target (for example loopback) and bypass private-address filtering in URL-fetching paths.\n\n## Severity Assessment\nRated **medium**: the bug weakens SSRF protections in URL fetch flows, but impact depends on reaching a URL-fetching path with attacker-controlled input and is generally constrained to internal network access attempts.\n\n## Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Affected: `>=2026.1.20 <=2026.2.17`\n- Latest published at patch time: `2026.2.17`\n- Patched release: `2026.2.19`\n\n## Security Policy Context\nPer `SECURITY.md`, OpenClaw's web/gateway surface is intended for local use by default, public internet exposure is out-of-scope, and prompt-injection reports are out-of-scope for bounty handling. This advisory tracks a core SSRF-guard bypass in fetch protections.\n\n## Impact\nThis can permit SSRF-style access attempts to internal/private network targets through URL ingestion/fetch paths that rely on shared hostname/IP blocking.\n\n## Fix\n- Added RFC 5214 ISATAP embedded-IPv4 detection to the shared SSRF classifier.\n- Centralized hostname/IP blocking through `isBlockedHostnameOrIp` and routed relevant validators to that shared path.\n- Added regression tests for ISATAP private vs public embedded IPv4 handling.\n\n## Fix Commit(s)\n- `d51929ecb52fe65e90bf36795f4247feb29eb8aa`\n\nOpenClaw thanks @zpbrent for reporting.","published":"2026-03-04T18:55:48Z","modified":"2026-03-04T19:04:48.938954Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.19"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/d51929ecb52fe65e90bf36795f4247feb29eb8aa","label":"openclaw/openclaw@d51929e"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-8cp7-rp8r-mg77"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/d51929ecb52fe65e90bf36795f4247feb29eb8aa"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-03-04T19:04:48.938954Z"}}
