Technical details

The Cyr to Lat reloaded – transliteration of links and file names plugin for WordPress (versions 1.3.3 and below) contains a broken access control vulnerability. The issue stems from a missing authorization check (CWE-862) in a plugin function, which fails to verify if the requesting user has the appropriate administrative permissions. An attacker authenticated with a low-privilege account, such as a Subscriber, can exploit this to execute functions intended for higher-privileged users. The vulnerability is addressed in version 1.3.4.
