CVE, Research URL

CVE-2025-11378

Date
Oct 18, 2025
Research Description
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.
Affected versions
max 6.3.5.

ShortPixel Image Optimizer &#8211; Optimize Images, Convert WebP &amp; AVIF # CVE-2026-4335

CVE, Research URL

CVE-2026-4335

Date
Mar 26, 2026
Research Description
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.
Affected versions
max 6.4.4.

CVE, Research URL

CVE-2026-1246

Date
Feb 05, 2026
Research Description
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.
Affected versions
max 6.4.3.
Status
