The Enable Media Replace plugin for WordPress up to version 4.2.2 contains an authorization bypass vulnerability. Authenticated users with author-level access or higher can modify the post_content of any published post referencing replaced media, including posts owned by administrators. This occurs because the plugin's doReplaceQuery() method performs a database-wide search-and-replace without verifying per-post editing permissions, allowing unauthorized content changes visible to all visitors.
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.
CVE-2026-97246 is a deserialization of untrusted data vulnerability in the ShortPixel Image Optimizer plugin for WordPress. It allows object injection, potentially leading to partial compromise of confidentiality and integrity. The issue affects versions from initial release up to 6.5.5. The vulnerability has a medium severity rating with a CVSS score of 4.9. No official patch or remediation details are provided in the available data.
The ShortPixel Image Optimizer – Optimize Images, Convert WebP & AVIF plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 6.5.5 via deserialization of untrusted input . This makes it possible for authenticated attackers, with author-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
The ShortPixel Adaptive Images – WebP, AVIF, CDN, Image Optimization plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.11.5. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify configuration options of third-party plugins including ShortPixel Image Optimizer, Autoptimize, WP Rocket, Imagify, and LiteSpeed Cache, as well as the plugin's own API key and account binding. Exploitation requires the respective third-party plugins to be installed, as the impact against those plugins' settings is only reachable when those plugins are present.
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.
The Enable Media Replace WordPress plugin up to version 4.1.8 is vulnerable to a stored cross-site scripting (XSS) flaw via the 'location_dir' parameter. Authenticated users with Author-level or higher privileges can inject malicious scripts that execute when other users view the affected pages. This vulnerability arises from insufficient input sanitization and output escaping.
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.
The ShortPixel Adaptive Images – WebP, AVIF, CDN, Image Optimization plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the API URL Setting in all versions up to, and including, 3.10.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
