OpenClaw: Node system.run approval bypass via parent-symlink cwd rebind
Summary
For host=node executions, approval context could be bypassed after approval-time by rebinding a writable parent symlink in cwd while preserving the visible cwd string.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected:
<= 2026.2.25 - Fixed:
>= 2026.2.26(planned next npm release)
Impact
A command approved for one filesystem location could execute from a different location if a mutable parent symlink changed between approval and execution.
Fix
- Added immutable approval-time plan preparation (
system.run.prepare) andsystemRunPlanV2canonical fields (argv,cwd,agentId,sessionKey). - Enforced canonical plan values through approval request storage and forwarding-time sanitization.
- Rejected mutable parent-symlink path components during approval-plan building to block symlink rebind bypass.
- Follow-up refactors centralized command catalogs and approval context/error handling to reduce future drift.
