What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

The Robin Image Optimizer WordPress plugin before 2.0.8 does not escape values that its bundled HTML parser re-emits into element attributes when a non-default image delivery mode is enabled, allowing unauthenticated users to submit content that is stored and later executed as Cross-Site Scripting in the browser of any user viewing an affected page, including administrators.
