Shortpixel vulnerabilities

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in ShortPixel ShortPixel Image Optimizer shortpixel-image-optimiser allows Stored XSS.This issue affects ShortPixel Image Optimizer: from n/a through 6.5.6.

Subscriber Cross Site Scripting (XSS) in ShortPixel Adaptive Images <= 3.11.3 versions.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in ShortPixel Enable Media Replace allows Stored XSS. This issue affects Enable Media Replace: from n/a through 4.2.1.

Unauthenticated Arbitrary File Deletion in ShortPixel Adaptive Images <= 3.11.4 versions.

The Enable Media Replace plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘location_dir’ parameter in all versions up to, and including, 4.1.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The ShortPixel Image Optimizer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the attachment post_title in all versions up to, and including, 6.4.3. This is due to insufficient output escaping in the getEditorPopup() function and its corresponding media-popup.php template. Specifically, the attachment's post_title is retrieved from the database via get_post() in AjaxController.php (line 435) and passed directly to the view template (line 449), where it is rendered into an HTML input element's value attribute without esc_attr() escaping (media-popup.php line 139). Since WordPress allows Authors to set arbitrary attachment titles (including double-quote characters) via the REST API, a malicious author can craft an attachment title that breaks out of the HTML attribute and injects arbitrary JavaScript event handlers. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts that execute whenever a higher-privileged user (such as an administrator) opens the ShortPixel AI editor popup (Background Removal or Image Upscale) for the poisoned attachment.

The Enable Media Replace plugin for WordPress is vulnerable to unauthorized modification of data due to an improper capability check on the 'RemoveBackGroundViewController::load' function in all versions up to, and including, 4.1.7. This makes it possible for authenticated attackers, with Author-level access and above, to replace any attachment with a removed background attachment.

The ShortPixel Image Optimizer plugin for WordPress is vulnerable to Arbitrary File Read via path traversal in the 'loadFile' parameter in all versions up to, and including, 6.4.2 due to insufficient path validation and sanitization in the 'loadLogFile' AJAX action. This makes it possible for authenticated attackers, with Editor-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information such as database credentials and authentication keys.

The ShortPixel Image Optimizer – Optimize Images, Convert WebP & AVIF plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'shortpixel_ajaxRequest' AJAX action in all versions up to, and including, 6.3.4. This makes it possible for authenticated attackers, with Contributor-level access and above, to export and import site options.

The Enable Media Replace plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's file_modified shortcode in all versions up to, and including, 4.1.6 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
