CVE-2026-35662
OpenClaw leaf subagents can bypass controlScope restrictions to send messages to child sessions
Description
## Summary Leaf subagents could still use the send action to message controlled child sessions even when their controlScope was narrower than children. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected: < 2026.3.22 - Fixed: >= 2026.3.22 - Latest released tag checked: `v2026.3.23-2` (`630f1479c44f78484dfa21bb407cbe6f171dac87`) - Latest published npm version checked: `2026.3.23-2` ## Fix Commit(s) - `7679eb375294941b02214c234aff3948796969d0` ## Release Status The fix shipped in `v2026.3.22` and remains present in `v2026.3.23` and `v2026.3.23-2`. ## Code-Level Confirmation - src/auto-reply/reply/commands-subagents/action-send.ts now threads controller context through the send path. - src/agents/subagent-control.ts now blocks send attempts unless the requester owns the target and has controlScope="children".
