The EWWW Image Optimizer WordPress plugin before 8.9.1 does not properly sanitize and restrict a value in post content before using it to dynamically load and execute a script in the page, allowing authenticated attackers with author-level access and above to inject arbitrary web scripts that run in the session of any user who views the affected page, including administrators. This is an incomplete fix of CVE-2026-15446: the origin and path restrictions added from 8.7.4 onward were each bypassable, so versions 8.7.4 through 8.9.0 remain affected.
