CVE-2026-44999 is a medium-severity vulnerability rated 6.3/10 on the CVSS scale. 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.. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
