{"id":"GHSA-7xhj-55q9-pc3m","summary":"OpenClaw's hook transform module path allows traversal and arbitrary JavaScript module loading","details":"## Summary\n\nOpenClaw hook mapping transforms could be loaded via absolute paths or `..` traversal, allowing arbitrary JavaScript module loading/execution in the gateway process when an attacker can modify hooks configuration.\n\n## Affected Versions\n\n- Affected: \u003e= 2.0.0-beta3 and \u003c= 2026.2.13\n- Fixed: 2026.2.14\n\n## Details\n\n`hooks.mappings[].transform.module` is dynamically imported and executed during webhook processing. Path resolution previously accepted absolute paths and did not enforce containment for relative paths, so a config-controlled transform could resolve outside the intended transforms directory.\n\n## Impact\n\nIf an attacker can write the OpenClaw config (or otherwise update hooks config through authenticated configuration mechanisms), they could point a hook mapping transform at an arbitrary module on disk and execute code with the gateway process privileges.\n\n## Reproduction (config-controlled module load)\n\n1. Configure a hook mapping that points to a transform path that escapes the transforms directory (for example via `..` traversal).\n2. Place a malicious ESM module at the resolved location that executes arbitrary code in the gateway process.\n3. Trigger the hook endpoint with the correct hook token.\n\n## Fix\n\nTransform loading is now constrained to the OpenClaw transforms root directory:\n\n- Root: `~/.openclaw/hooks/transforms`\n- `hooks.transformsDir` must be within that directory\n- `transform.module` must be within the selected transforms directory\n\nAttempts to escape the root (absolute paths outside, `..` traversal) are rejected.\n\nFix commit(s):\n\n- a0361b8ba959e8506dc79d638b6e6a00d12887e4\n- 18e8bd68c5015a894f999c6d5e6e32468965bfb5\n\n## Credits\n\nOpenClaw thanks @akhmittra for reporting.","aliases":["CVE-2026-28393"],"modified":"2026-03-06T01:16:25.062189Z","published":"2026-03-03T18:09:54Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-03-03T18:09:54Z","nvd_published_at":"2026-03-05T22:16:15Z","cwe_ids":["CWE-22","CWE-427"],"severity":"HIGH"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-7xhj-55q9-pc3m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-28393"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/18e8bd68c5015a894f999c6d5e6e32468965bfb5"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/a0361b8ba959e8506dc79d638b6e6a00d12887e4"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-beta-arbitrary-javascript-module-loading-via-hook-transform-path-traversal"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.0.0-beta3"},{"fixed":"2026.2.14"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 2026.2.13","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-7xhj-55q9-pc3m/GHSA-7xhj-55q9-pc3m.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
