description

OMGF WordPress plugin versions through 6.3.10 can retain attacker-controlled content that is later interpreted as browser script. An unauthenticated attacker may affect visitors to the resulting content when the server exposes the temporary file without a Content-Type or X-Content-Type-Options header.

mitigation

Configure the web server to send an appropriate Content-Type and X-Content-Type-Options: nosniff for affected temporary-file responses, or prevent direct access to retained .tmp files. Update the plugin when a release newer than 6.3.10 is confirmed to address the issue.
