OpenClaw's Slack plugin approvals used the exec approver gate for plugin actions, allowing Slack users authorized only for exec approvals to resolve plugin approvals improperly. This vulnerability affects versions prior to 2026.5.12. The issue could lead to plugin actions being approved outside the intended approval split, depending on operator configuration and input trust levels. The vulnerability is mitigated by patching to version 2026.5.12 or later and by manual review of Slack approval actions until patched. Additional mitigations include maintaining narrow allowlists and disabling the affected feature when not needed.
