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.
A flaw was found in crun where containers were incorrectly started with non-empty default permissions. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable. This Incorrect Default Permissions vulnerability could allow attackers to access resources due to overly permissive default settings.
An issue was discovered in crun before 0.10.5. Rated high severity (CVSS 8.6), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
