CVE-2026-48943 Details
Description
K2 ≤ 2.24 contains a mass-assignment defect in the K2 system user plugin `plg_user_k2`. A Registered Joomla user, by including the field `K2UserForm=1` in a standard `com_users` `profile.save` POST, can write arbitrary values into the `notes`, `image`, and `plugins` columns of their own row in the `#__k2_users` table — none of which are exposed by the K2 frontend profile-edit form.
A mass assignment vulnerability has been identified in the K2 system user plugin, specifically in versions through 2.24. This vulnerability allows registered Joomla users to inject arbitrary values into their own K2 user profiles. By including the field 'K2UserForm=1' in a standard 'com_users' 'profile.save' POST request, users can manipulate the 'notes', 'image', and 'plugins' columns of the '#__k2_users' table. Notably, these fields are not accessible through the K2 frontend profile-edit form.
