4.5 · MEDIUMOverview
CVE-2025-65105 is a medium-severity vulnerability affecting lfprojects apptainer. It was published on December 2, 2025 and has a CVSS 3.1 base score of 4.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 4.5, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
Apptainer is an open source container platform. In Apptainer versions less than 1.4.5, a container can disable two of the forms of the little used --security option, in particular the forms --security=apparmor:<profile> and --security=selinux:<label> which otherwise put restrictions on operations that containers can do. The --security option has always been mentioned in Apptainer documentation as being a feature for the root user, although these forms do also work for unprivileged users on systems where the corresponding feature is enabled. Apparmor is enabled by default on Debian-based distributions and SElinux is enabled by default on RHEL-based distributions, but on SUSE it depends on the distribution version. This vulnerability is fixed in 1.4.5.
Remediation
Check the references section for vendor advisories and patches from lfprojects. Update apptainer to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
