A local attacker with access to the cPanel Logaholic interfaces could create a session file in this directory with a crafted payload intended to execute arbitrary code as the cpanel-logaholic user as the session was loaded by the Logaholic interfaces inside cPanel. Logaholic now uses a non-world-writable directory for session data, and as a precaution, database caching.
