{"id":"GHSA-4w7m-58cg-cmff","summary":"OpenClaw: Leaf subagents could steer sibling sessions across sandbox boundaries","details":"## Summary\nIn affected versions of `openclaw`, sandboxed leaf subagents could still access the `subagents` control surface and resolve against the parent requester scope instead of remaining confined to their own session tree.\n\n## Impact\nA low-privilege sandboxed leaf worker could steer or kill a sibling run owned by the same requester and cause that sibling to execute with its own broader tool policy. This is a sandbox and session-scope boundary bypass.\n\n## Affected Packages and Versions\n- Package: `openclaw` (npm)\n- Affected versions: `\u003c= 2026.3.8`\n- Fixed in: `2026.3.11`\n\n## Technical Details\nLeaf subagents retained the `subagents` tool, and subagent control requests were authorized against the parent requester scope rather than the caller's own spawned descendants. The control path prevented only self-targeting, not cross-sibling steering.\n\n## Fix\nOpenClaw now removes `subagents` control access from leaf subagents by default, scopes subagent control to the caller's own descendants, and rejects `steer` and `kill` requests that target runs outside that descendant tree. The fix shipped in `openclaw@2026.3.11`.\n\n## Workarounds\nUpgrade to `2026.3.11` or later.","aliases":["CVE-2026-32915"],"modified":"2026-07-08T07:56:35.866736804Z","published":"2026-03-13T15:47:34Z","database_specific":{"github_reviewed_at":"2026-03-13T15:47:34Z","nvd_published_at":null,"cwe_ids":["CWE-269"],"severity":"HIGH","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-4w7m-58cg-cmff"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/releases/tag/v2026.3.11"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.3.11"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-4w7m-58cg-cmff/GHSA-4w7m-58cg-cmff.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
