CVE-2026-78683
Description détaillée
NLTK before 3.10.0 (affected versions <=3.9.4) contains an unsafe pickle deserialization vulnerability in the TransitionParser.parse() method (nltk/parse/transitionparser.py). The method calls pickle_load() with the default restricted=False, routing deserialization through WarningUnpickler, which does not override find_class() and therefore permits arbitrary class resolution. When an application loads an attacker-crafted model file, embedded pickle gadget chains execute arbitrary Python code with the privileges of the user running the application. NLTK provides a RestrictedUnpickler for safe deserialization, but it is not used by production code paths. Fixed in 3.10.0.

Medical Practice Management System developed by Le-yan has a Remote Code Execution vulnerability. Unauthenticated remote attackers can execute arbitrary OS commamnds via a crafted HTML page.
CVE-2026-75982
The LearnPress plugin for WordPress is vulnerable to unauthorized modification of arbitrary WordPress options in versions up to, and including, 4.4.4 via the learnpress_create_page AJAX action. The LP_Admin_Ajax::create_page() handler only checks the edit_pages capability and a wp_rest nonce (both available to Editors), then reads the field_name parameter from the request without restricting it to a learn_press_* allow-list before passing it as the option key to LP_Helper::create_page(), which calls update_option($key_option, $page_id). This makes it possible for authenticated attackers, with Editor-level access and above, to update arbitrary WordPress options to a positive integer (a newly created page ID), enabling actions such as flipping users_can_register to a truthy value to open public registration, corrupting active_plugins to break the site, or otherwise tampering with site-wide settings normally reserved for administrators.
CVE-2026-75019
The Cozy Blocks – Page Builder for Gutenberg Editor & FSE with 700+ Patterns, 58 Blocks & Templates plugin for WordPress is vulnerable to Stored Cross-Site Scripting via cozyHoverEffect Block Attribute in all versions up to, and including, 2.2.16 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 payload survives wp_kses_post on save because it contains no angle brackets — only a double-quote breakout of the cozyHoverEffect.boxShadow.color attribute value — allowing event-handler injection at the render stage.
