  "summary": "CVE-2026-19816 is fixed in packagekit on 1 platform by DEBIAN-CVE-2026-19816 (version 1.4.0-1), released September 17, 2026. It is not reported as exploited. Patch Radar priority: High.",
  "title": "packagekit: A flaw was found in PackageKit",
  "description": "A flaw was found in PackageKit. PackageKit skips the polkit authorization check for transactions carrying the SIMULATE (dry-run) flag. In the dnf5 backend, the RepoRemove handler ignores that contract and always executes the real transaction because its guard is written as (role == REPO_REMOVE || !SIMULATE), which is always true for RepoRemove. An unprivileged local user can therefore perform a genuine package uninstall while claiming to simulate. This vulnerability only affects systems using PackageKit with the dnf5 backend.",
