CVE-2025-47786

Emlog is an open source website building system. Version 2.5.13 has a stored cross-site scripting vulnerability that allows any registered user to construct malicious JavaScript, inducing all website users to click. In /admin/comment.php, the parameter perpage_num is not validated and is directly stored in the admin_commend_perpage_num field of the emlog_options table in the database. Moreover, the output is not filtered, resulting in the direct output of malicious code. As of time of publication, it is unclear if a patch exists.
