What happened

Remote Code Execution (RCE) vulnerability in Widget Options versions 4.2.5 and earlier, caused by an author-level flaw that allows code to be executed remotely.

Are you affected?

You are affected if your site runs Widget Options version 4.2.5 or earlier.

What to do

  1. Check whether Widget Options is installed and note its version
  2. Update to a fixed version as soon as the vendor releases one, or remove the plugin if no fix is available
