What is CVE-2026-72694?

A vulnerability exists in MRTG where, if the daemon is initiated as a root user and later drops privileges, it falls prey to a symbolic link exploitation. Through this flaw, a low-privileged attacker can influence the symlink within the process ID (PID) file path. By doing so, the attacker can mislead the root process to alter the ownership of existing files, granting unauthorized access to sensitive files and allowing alterations to be made without consent.
