EPSS Score14.2%

EPSS (Exploit Prediction Scoring System) estimates a 14.2% chance this CVE is exploited in the wild within the next 30 days — higher than 97% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.

Microsoft Windows Task Scheduler contains a privilege escalation vulnerability that can allow an attacker-provided, local application to escalate privileges outside of its AppContainer, and access privileged RPC functions.
