Does this affect you?

It affects getk2.org K2 extension for Joomla and 1 other product. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

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.
