CVE-2026-54584
mport is the MidnightBSD Package Manager.
Overview
CVE-2026-54584 is a known-severity vulnerability. It was published on September 21, 2026.
Technical description
mport is the MidnightBSD Package Manager. mport before 2.7.8 used TMPDIR while extracting package metafiles, including when running as root or in setuid/setgid contexts. An attacker able to control the environment for a privileged mport invocation could redirect temporary metadata extraction to an attacker-controlled location. PR 123 ignores unsafe TMPDIR values in privileged contexts and rejects empty TMPDIR. This issue has been patched in version 2.7.8.
