CVE-2026-13441

HIGH7.2

Published 2026-07-09 · Source security@wordfence.com

Description

The EventPrime – Events Calendar, Bookings and Tickets plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'new_event_type_background_color' parameter in all versions up to, and including, 4.3.4.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with custom-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the plugin's Guest Submissions setting (allow_submission_by_anonymous_user) to be enabled, which allows unauthenticated attackers to submit event types via the frontend form; when that setting is disabled, exploitation requires at minimum a subscriber-level authenticated account.

CVE-2026-59692
A stack buffer overflow vulnerability was found in GStreamer's DTLS plugin. During a DTLS handshake, the peer certificate Subject Distinguished Name is printed into a fixed-size 2048-byte stack buffer without bounds checking. A remote unauthenticated attacker can send a certificate with an oversized Subject DN that exceeds the buffer, causing a stack buffer overflow and process crash, resulting in denial of service.

CVE-2026-59691
A heap buffer overflow vulnerability was found in GStreamer's rfbsrc plugin. When a client connects to a malicious RFB/VNC server that advertises a 16bpp framebuffer and sends Hextile-encoded updates, the Hextile background fill path writes 32-bit pixel values into a buffer allocated for 16-bit pixels. This type mismatch causes an out-of-bounds heap write that can lead to denial of service (process crash) and potential memory corruption.

CVE-2026-4275
The Divi Torque Lite – Divi Theme, Divi Builder & Extra Theme plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.2.3. This is due to the use of '__return_true' as the permission_callback for the /install_plugin and /activate_plugin REST API endpoints, which bypasses WordPress's built-in REST API nonce verification. Although the endpoint callbacks contain internal current_user_can() checks, the absence of nonce verification means that a forged cross-site request from a logged-in administrator's browser will pass the capability check via the admin's session cookies. This makes it possible for unauthenticated attackers to install arbitrary plugins from WordPress.

The Bit Form – Contact Form, Payment Forms, Multi Step Forms, Calculator & Custom Form Builder plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the deleteFiles function in all versions up to, and including, 3.1.1 This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config).
