What is CVE-2026-44999?

A vulnerability in OpenClaw prior to version 2026.4.20 allows for improper preservation of untrusted labels in isolated cron awareness events. This failure can lead to the recording of webhook-triggered cron agent outputs as trusted system events, enabling attackers to amplify prompt-injection attacks by misrepresenting untrusted events as legitimate and trusted interactions within the system.
