{"id":"CVE-2026-54575","published":"2026-09-17T17:16:42.420","lastModified":"2026-09-21T21:17:04.700","description":"mport is the MidnightBSD Package Manager. Prior to 2.7.8, privileged package fetch and cache-cleaning operations used race-prone path handling across libmport/fetch.c, libmport/clean.c, libmport/util.c, libmport/bundle_read_install_pkg.c, libmport/delete_primative.c, and libexec/mport.create/mport.create.c. A local attacker with write access to a participating package cache or staging path could race path checks and replacement operations to redirect package downloads, cleanup, or install-related side effects outside the intended cache. The affected lifecycle helper paths also used shell-form invocation, increasing command-line interpretation risk during privileged helper execution. This issue is fixed in version 2.7.8.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-78","CWE-367"],"vendors":[],"products":[],"references":[{"url":"https://github.com/MidnightBSD/mport/commit/29154b0fdfb5806568ed1277e88d942bad6d1169","tags":[]},{"url":"https://github.com/MidnightBSD/mport/pull/118","tags":[]},{"url":"https://github.com/MidnightBSD/mport/releases/tag/2.7.8","tags":[]},{"url":"https://github.com/MidnightBSD/mport/security/advisories/GHSA-h387-g4pf-28cj","tags":[]}],"exploitRefs":[{"url":"https://github.com/MidnightBSD/mport/commit/29154b0fdfb5806568ed1277e88d942bad6d1169","tags":[]},{"url":"https://github.com/MidnightBSD/mport/pull/118","tags":[]},{"url":"https://github.com/MidnightBSD/mport/releases/tag/2.7.8","tags":[]},{"url":"https://github.com/MidnightBSD/mport/security/advisories/GHSA-h387-g4pf-28cj","tags":[]}],"hasPoc":true,"ai":null}
