strange mysql user created with every login?!?

StoneM

New Pleskian
Hi,

Environment: Plesk 9.2 on Linux CentOS 5.3

Checking through my MySQL database users and noted strange users with the name: bug115166_XXXXX (where XXXXX is a number). The users don't have GRANT, no privileges, they do have a password assigned, and they don't have access to anything. The host is %;

I deleted the users and noted that they keep coming back.

I then realized that a new "bug115166_XXXXX" user appears every time I log out/in to Plesk!

..is my server compromised? ..where in plesk could I look to find how this user is being created? ..is "bug115166" associated with Plesk somehow? MySQL thing?

Thanks for any insight, Monk
