Threat database

The EWWW Image Optimizer plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via REQUEST_URI Parameter Key in all versions up to, and including, 8.7.7 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Successful exploitation requires that the enable_help option is active, as the vulnerable HelpScout Beacon script block is only emitted when that setting is enabled.

The EWWW Image Optimizer WordPress plugin up to version 8.7.3 contains a stored cross-site scripting (XSS) vulnerability via the 'data-script' lazy load attribute in post content. Authenticated users with contributor-level access or higher can inject malicious scripts that execute when other users view the affected pages. This occurs due to insufficient input sanitization and output escaping in the plugin's handling of the 'data-script' attribute combined with the lazysizes ls.unveilhooks addon dynamically inserting attacker-controlled scripts into the DOM.
