No confirmed exploitation observed yet

CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
A successful exploit gives an attacker total control of the affected component, not partial access.
CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

Description

Summary

Heartbeat owner downgrade missed local async exec completion events.

Affected Packages / Versions

Package: openclaw
Ecosystem: npm
Affected versions: >= 2026.3.31 < 2026.4.10
Patched versions: >= 2026.4.10

Impact

Local background exec completion text could be missed by heartbeat owner-downgrade detection, leaving a run in a more privileged context than intended after untrusted completion content.

Technical Details

The fix expands exec-completion detection to local background exec formats and adds targeted tests.

Fix

The issue was fixed in #64376. The first stable tag containing the fix is v2026.4.10, and [email protected] includes the fix.
