Crun
Monthly
crun versions 1.19 through 1.26 misparse the `-u` (--user) option during container execution, causing a numeric UID value of 1 to be incorrectly interpreted as UID 0 (root) instead, resulting in privilege escalation where containerized processes execute with root privileges instead of the intended unprivileged user. The vulnerability affects the containers/crun OCI runtime container (cpe:2.3:a:containers:crun:*:*:*:*:*:*:*:*) and has been patched in version 1.27. No public exploit code or active exploitation has been identified, though the EPSS score of 0.01% (percentile 2%) indicates minimal real-world exploitation likelihood despite the privilege escalation tag.
