{"id":"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: `\u003e=2026.1.20 \u003c=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.","modified":"2026-03-04T19:04:48.938954Z","published":"2026-03-04T18:55:48Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-03-04T18:55:48Z","nvd_published_at":null,"cwe_ids":["CWE-918"]},"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"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2026.1.20"},{"fixed":"2026.2.19"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-8cp7-rp8r-mg77/GHSA-8cp7-rp8r-mg77.json"}}],"schema_version":"1.9.0","severity":[{"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"}]}
