Descripción técnica

The Vigilant – 100% Free Security Suite: Firewall, 2FA, Login, Headers, Scanner… plugin for WordPress is vulnerable to Stored Cross-Site Scripting via User-Agent Header in all versions up to, and including, 2.10.2 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 malicious payload is delivered passively by any unauthenticated visitor who triggers a failed login attempt with a crafted User-Agent header, requiring no further interaction from the attacker once stored.

———The WP-Members Membership Plugin plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via URL Query String in all versions up to, and including, 3.5.6 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Successful exploitation requires the victim to first visit the attacker-crafted URL and then click the Terms of Service link rendered on the resulting registration page.4h CVE-2026-818257.2 ALT

———The Simple Ajax Chat – Add a Fast, Secure Chat Box plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Chat Message in all versions up to, and including, <= 20260811 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 nonce protecting chat message submission is publicly visible on the chat page, rendering it ineffective as an authentication barrier and allowing fully unauthenticated attackers to submit malicious messages that are stored persistently and rendered to all visitors on every page load.4h CVE-2026-74386.4 MED

———The Bold Timeline Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `supertitle` and `subtitle` attributes of the `bold_timeline_item` shortcode in all versions up to, and including, 1.2.8 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.4h CVE-2026-781726.1 MED

———The Themify – WooCommerce Product Filter plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via Query Parameter Name in all versions up to, and including, 1.5.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.4h CVE-2026-771506.1 MED

———The Unlimited Elements For Elementor plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via 'data[name]' Parameter in all versions up to, and including, 2.0.16 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The show_preview AJAX action is registered for unauthenticated users and is gated only by a nonce, which an unauthenticated attacker can retrieve by loading any publicly accessible page that emits it.4h CVE-2026-199856.1 MED

———The Relevanssi – A Better Search plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in versions up to, and including, 4.28.1 via the 's', 'post_types', and 'orderby' request parameters. This is due to insufficient input sanitization and output escaping in the relevanssi_debug_array() function in lib/debug.php, which dumps user-supplied query variables through print_r() inside a <pre> block without HTML escaping. The debug path is enabled by supplying the relevanssi_debug=on request parameter when the administrator has previously enabled the 'Debugging mode' setting; the gate itself is a configuration check with no capability, nonce, or logged-in check (the vendor explicitly suppresses nonce verification on that line). This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a specially crafted link.4h
