The fix now fail-closes ACP spawn from sandboxed requester sessions and rejects `sandbox=\"require\"` for `runtime=\"acp\"`.\n\n### Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Latest published npm version at triage time: `2026.3.1` (March 2, 2026)\n- Vulnerable range: `<=2026.3.1`\n- Patched release: `2026.3.2` (released)\n\n### Technical Details\n- Root cause: `runtime=\"subagent\"` enforced sandbox inheritance, while `runtime=\"acp\"` did not enforce equivalent sandbox/runtime checks.\n- Security impact: sandbox-boundary bypass into host-side ACP initialization.\n- Fixed behavior:\n  - deny ACP spawn when requester runtime is sandboxed\n  - deny `sessions_spawn` with `runtime=\"acp\", sandbox=\"require\"`\n  - align sandboxed prompt guidance to avoid advertising blocked ACP paths\n\n### Fix Commit(s)\n- `ac11f0af731d41743ba02d8595f4d0fe747336e3`\n- `c703aa0fe92df9fb71cf254fc46991e05fba2114`","published":"2026-03-03T21:31:57Z","modified":"2026-03-04T15:11:35.777090Z","cvss":{"score":8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.3.2"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/ac11f0af731d41743ba02d8595f4d0fe747336e3","label":"openclaw/openclaw@ac11f0a"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-474h-prjg-mmw3"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/ac11f0af731d41743ba02d8595f4d0fe747336e3"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/c703aa0fe92df9fb71cf254fc46991e05fba2114"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-03-04T15:11:35.777090Z"}}
