Threats affecting pkg:github/packagekit/PackageKit

CVE-2026-19816 is a high-severity vulnerability in PackageKit when used with the dnf5 backend. The flaw allows an unprivileged local user to bypass authorization checks and perform an actual package uninstall by exploiting incorrect handling of the SIMULATE (dry-run) flag. This occurs because the RepoRemove handler's guard condition is flawed, causing it to always execute the real transaction instead of simulating it. The issue affects PackageKit version 1.3.4.

A vulnerability has been found in PackageKit up to 1.3.5. Affected is the function g_file_test of the file src/pk-transaction.c of the component API. Such manipulation of the argument frontend-socket leads to improper authorization. The attack can be executed remotely. The exploit has been disclosed to the public and may be used.
