# Security Bug Causing Problems with MEC Lite

 * I had MEC Lite installed on my company’s website, but Jetpack detected a security
   issue this morning. I tried uninstalling and reinstalling the plugin – hoping
   I had missed an update.
 * My coworker was adding a new event and was unable to save it or upload an image.
   When he tried to preview the event, he received a 403 error. Worried about the
   bug affecting other elements of our site, I have uninstalled it again. Is anyone
   else having security problems? Is there an expected patch being worked on to 
   update the plugin?

 * For reference, here is a link found detailing the problem. I would recommend 
   anyone else experiencing this error roll back to the previous update until a 
   fix is published.

 * [@abachechi3](https://wordpress.org/support/users/abachechi3/) – I don’t think
   rolling back will help, because this vulnerability impacts all versions up to
   5.1.6 (the current version, as of now).
 * Also would appreciate an update from Webnus on this.
