This is due to insufficient input sanitization in the `ao_metabox_save()` function and missing output escaping when the value is rendered into a `<link>` tag in `autoptimizeImages.php`. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page, granted the \"Image optimization\" or \"Lazy-load images\" setting is enabled in the plugin configuration."}], "lastModified": "2026-03-23T14:32:02.800", "sourceIdentifier": "security@wordfence.com"}
