Oveleon Cookie Bar is a cookie bar is for the Contao Open Source CMS and allows a visitor to define cookie & privacy settings for the website. Prior to versions 1.16.3 and 2.1.3, the block/locale
endpoint does not properly sanitize the user-controlled locale
input before including it in the backend’s HTTP response, thereby causing reflected cross-site scripting. Versions 1.16.3 and 2.1.3 contain a patch for the vulnerability.
