CVE-2026-54582

mport is the MidnightBSD Package Manager. Prior to 2.7.8, package installation lacked a preflight check for incoming non-directory assets that already existed on disk. The affected logic across libmport/checkpreconditions.c, libmport/installprimative.c, and libmport/mportprivate.h did not apply...

CVE-2026-54580

mport is the MidnightBSD Package Manager. Prior to 2.7.8, libmport/util.c did not make every truncated, corrupt, or failed zstd stream fatal in mportdecompresszstd, and libmport/fetch.c did not consistently propagate those failures to index-fetch callers. A malicious or faulty mirror could supply...

CVE-2026-54576

mport is the MidnightBSD Package Manager. Prior to 2.7.8, doactualinstall in libmport/bundlereadinstallpkg.c used path-based lstat, chown, stat, and chmod operations while installing package files. A local attacker with write access to a target directory could replace a checked file with a symlin...

CVE-2026-54578

mport is the MidnightBSD Package Manager. Prior to 2.7.8, mportverifypackage in libmport/verify.c could continue after MD5File or SHA256File failed and compare an expected checksum with stale data in the hash buffer rather than a newly computed digest. An attacker able to influence an installed...

CVE-2026-54576

mport , the MidnightBSD Package Manager, is affected by a symlink TOCTOU vulnerability in do_actual_install() (file libmport/bundle_read_install_pkg.c) prior to version 2.7.8 . The function used path-based lstat(), chown(), stat(), and chmod() operations during package installation. A local attac...

CVE-2026-54578 mport verify can compare stale checksum data after hashing failures

mport is the MidnightBSD Package Manager. Prior to 2.7.8, mportverifypackage in libmport/verify.c could continue after MD5File or SHA256File failed and compare an expected checksum with stale data in the hash buffer rather than a newly computed digest. An attacker able to influence an installed...

CVE-2026-54578

mport , the MidnightBSD Package Manager, contains a flaw in mport_verify_package() (libmport/verify.c) prior to version 2.7.8. After MD5File() or SHA256_File() fails, the function continues and compares an expected checksum against stale data in the hash buffer rather than a newly computed digest...

CVE-2026-54586 mport permits repository and package mirror fetches over insecure transport

mport is the MidnightBSD Package Manager. Prior to 2.7.8, the mportfetchindex, mportfetchbootstrapindex, and mportfetchbundle paths in libmport/fetch.c accepted non-HTTPS repository and package mirror URLs without a urlishttps enforcement check. When a cleartext URL was configured or returned by...

CVE-2026-54585 mport sample file handling can write outside the configured root

mport is the MidnightBSD Package Manager. Prior to 2.7.8, createsamplefile in libmport/bundlereadinstallpkg.c did not constrain absolute source and destination paths from the sample-file manifest directive to mport-root. A malicious or malformed package manifest could therefore direct privileged...
