This CVE was published Sep 30, 2026 and is one of 5 known issues for this plugin.
Update, patch or deactivate.
Update Image Optimizer to 1.7.7 or a later supported release. Restrict access to the affected functionality until updated; the export does not provide enough implementation detail for a source-level patch.
