What is CVE-2025-67905?

Malwarebytes AdwCleaner, prior to version 8.7.0, operates with elevated privileges and performs an unsafe log file deletion process. This design flaw allows a non-administrator user to escalate their privileges to SYSTEM by manipulating symbolic links. Specifically, an attacker can create a file in a targeted folder, which enables them to intervene in the application’s log file deletion sequence, potentially compromising security and gaining unauthorized access to sensitive system resources.
