CVE-2026-35662 (GCVE-0-2026-35662)

Vulnerability from cvelistv5 – Published: 2026-04-10 16:03 – Updated: 2026-04-10 18:24 X_Open Source

Title

OpenClaw < 2026.3.22 - Missing controlScope Enforcement in Send Action

Summary

OpenClaw before 2026.3.22 fails to enforce controlScope restrictions on the send action, allowing leaf subagents to message controlled child sessions beyond their authorized scope. Attackers can exploit this by using the send action to communicate with child sessions without proper scope validation, bypassing intended access control restrictions.
