CVE-2026-30892

7.8 highEPSS 0.2%

High (7.8) in crun project crun. EPSS 0.2% chance of exploitation in the next 30 days.

crun is an open source OCI Container Runtime fully written in C. In versions 1.19 through 1.26, the `crun exec` option `-u` (`--user`) is incorrectly parsed. The value `1` is interpreted as UID 0 and GID 0 when it should have been UID 1 and GID 0. The process thus runs with higher privileges than expected. Version 1.27 patches the issue.
