CVE-2026-44999
OpenClaw < 2026.4.20 - Improper Trust Labeling in Isolated Cron Awareness Events
Description

OpenClaw before 2026.4.20 fails to properly preserve untrusted labels for isolated cron awareness events, allowing webhook-triggered cron agent output to be recorded as trusted system events. Attackers can exploit this trust-labeling issue to strengthen prompt-injection attacks by rendering untrusted events as trusted System events.
