CVE-2026-8438

The Master Addons For Elementor – Widgets, Extensions, Theme Builder, Popup Builder & Template Kits plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'jtlma_custom_js' Page Setting (Custom JS Extension) in all versions up to, and including, 3.1.0 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 unfiltered_html capability check is only enforced during Elementor control registration (UI rendering) and not during the save process, enabling Author-level users to inject the jtlma_custom_js setting directly via a crafted POST request to admin-ajax.php?action=elementor_ajax, bypassing the UI-level restriction entirely.

The Integration for Freshsales – Contact Form 7, WPForms, Elementor, Gravity Forms and More plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Form Submission Data in all versions up to, and including, 1.0.15 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The injected payload only executes when a CRM API call fails for the submitted form and an administrator subsequently views the error log details modal in the WordPress admin panel.

The Simple SEO Slideshow plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Shortcode Attributes in all versions up to, and including, 1.2.8 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. WordPress KSES does not strip malicious shortcode attribute values on post save, allowing contributor-level users to persist payloads that execute for any visitor, including administrators reviewing the post.

The Express Payment For Stripe plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'type' attribute of the [stripe-express] shortcode in versions up to, and including, 1.28.0. This is due to insufficient input sanitization and output escaping on the shortcode attribute value, which is concatenated into an HTML attribute in the rendered output of the register_shortcode() function without being passed through esc_attr() or any other escaping function. 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.

OpenXDMoD is an open framework for collecting and analyzing HPC metrics. Prior to version 11.0.3, an authenticated attacker can inject malicious JavaScript into their Open XDMoD user profile and abuse the password reset functionality to email a link to an HTML page, which when visited by the victim, reflects and executes the unsanitized payload in the victim's browser, potentially leading to credential capture and Open XDMoD account takeover. All deployments of Open XDMoD prior to 11.0.3 are impacted. This issue was reported privately on 2026-04-06, and at this time there is no evidence that this vulnerability has been exploited in the wild. The vulnerability was patched in Open XDMoD 11.0.3 on 2026-05-12. As a workaround, apply the patch manually.

The WP User Manager – User Profile Builder & Membership plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 2.9.17 via the (profile template scope) function. This makes it possible for unauthenticated attackers to include and execute arbitrary .php files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included.

The Admin Columns plugin for WordPress is vulnerable to PHP Object Injection leading to Remote Code Execution in versions up to and including 7.0.18. This is due to the use of `unserialize()` without an `allowed_classes` restriction in the `IdsToCollection::get_ids_from_string()` function, which processes attacker-controlled post meta values without proper validation. This makes it possible for authenticated attackers with Contributor-level access and above to inject a serialized PHP object into a post's custom meta field and trigger arbitrary code execution by exploiting a bundled POP gadget chain, resulting in remote code execution as the web server user.

MoviePilot contains a path traversal vulnerability in the AliPan, U115, and Rclone cloud storage download handlers where the local destination path is constructed by concatenating the configured download directory with a filename taken directly from remote cloud API metadata without basename normalization or path validation. An attacker who controls a filename returned by a remote cloud storage API can include traversal sequences ../ in the filename to cause downloaded content to be written outside the configured download directory, potentially overwriting arbitrary files including configuration or plugin files reachable by the application process.

Markdown Preview Enhanced 0.8.x with crossnote engine 0.9.28 contains a code injection vulnerability in the WaveDrom rendering pipeline that allows attackers to execute arbitrary JavaScript by embedding malicious content in a wavedrom fenced code block within a crafted Markdown document. Attackers can exploit the unsanitized passing of wavedrom block content to window.eval() in the VS Code webview context to abuse the extension's message passing and invoke arbitrary file writes on the local filesystem.
