Remote code execution in the WordPress 'Responsive Slider by MetaSlider' plugin (versions ≤3.106.0) allows authenticated users with Editor-level privileges to inject and execute arbitrary code on the underlying server. The flaw is tracked as CWE-94 (Improper Control of Generation of Code) and carries a CVSS 3.1 score of 9.1 because exploitation crosses a scope boundary, but no public exploit identified at time of analysis and the issue is not listed in CISA KEV.
PHP object injection in MetaSlider Responsive Slider plugin (WordPress) through version 3.106.0 allows authenticated administrators with high privileges to execute arbitrary code by deserializing untrusted data. The vulnerability requires authenticated high-privilege access (PR:H), limiting exploitation to compromised admin accounts or malicious insiders. EPSS data not available; no confirmed active exploitation or public POC identified at time of analysis.
Stored XSS in the MetaSlider WordPress plugin (versions up to and including 3.111.0) allows authenticated Author-level users to inject arbitrary JavaScript via the unprotected 'delay' post meta setting, which executes in the browser of any visitor who loads a page containing the affected slider. The attack path leverages the WordPress XML-RPC API: the ml-slider custom post type is registered without custom capability restrictions and the ml-slider_settings meta key is unprotected, enabling Author-level accounts to plant persistent payloads that bypass normal UI-layer permission checks. This vulnerability is not listed in CISA KEV and no public exploit code has been identified at time of analysis; a patched release (3.111.1) is confirmed by the WordPress plugin SVN changeset.
The Slider, Gallery, and Carousel by MetaSlider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘aria-label’ parameter in all versions up to, and including, 3.98.0 due to insufficient input sanitization and output escaping. 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 Slider, Gallery, and Carousel by MetaSlider WordPress plugin before 3.95.0 does not sanitise and escape some of its settings, which could allow high privilege users such as editor to perform. Rated low severity (CVSS 3.5), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.

The Slider, Gallery, and Carousel by MetaSlider - Responsive WordPress Slideshows plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'metaslider' shortcode in all. Rated medium severity (CVSS 6.4), this vulnerability is remotely exploitable, low attack complexity. This Cross-Site Scripting (XSS) vulnerability could allow attackers to inject malicious scripts into web pages viewed by other users.
The Slider, Gallery, and Carousel by MetaSlider WordPress plugin 3.29.0 does not sanitise and escape a parameter before outputting it back in the page, leading to a Reflected Cross-Site Scripting. Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
The Slider, Gallery, and Carousel by MetaSlider WordPress plugin before 3.27.9 does not sanitise and escape some of its Gallery Image parameters, which could allow high privilege users such as admin. Rated medium severity (CVSS 4.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
Cross-site scripting (XSS) vulnerability in the Meta Slider (ml-slider) plugin 2.5 for WordPress allows remote attackers to inject arbitrary web script or HTML via the id parameter to. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable. Public exploit code available and no vendor patch available.
