OpenClaw: Gateway Plugin Subagent Fallback `deleteSession` Uses Synthetic `operator.admin`

Summary

Gateway Plugin Subagent Fallback deleteSession Uses Synthetic operator.admin

Affected Packages / Versions

  • Package: openclaw
  • Affected versions: <= 2026.3.24
  • First patched version: 2026.3.25
  • Latest published npm version at verification time: 2026.3.24

Details

Gateway plugin subagent fallback deleteSession previously dispatched sessions.delete with a synthetic operator.admin runtime scope when no request-scoped client existed. Commit b5d785f1a59a56c3471f2cef328f7c9a6c15f3e7 binds deletion to the caller scope instead of minting admin scope.

Verified vulnerable on tag v2026.3.24 and fixed on main by commit b5d785f1a59a56c3471f2cef328f7c9a6c15f3e7.
