CVE-2026-12410
Link following vulnerability in the Uninstaller component in CCleaner prior to 7.10.1464 on Windows allows a local, low-privileged attacker to escalate privileges to SYSTEM via a symlink/junction created during application uninstallation, which CCleaner follows when deleting the application's data folder with elevated integrity.
