CVE-2024-11878

MEDIUM

Category Post Slider <= 1.4 - Authenticated Stored Cross-Site Scripting via Shortcode Attributes

Title source: llm

Description

The Category Post Slider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'category-post-slider' shortcode in all versions up to, and including, 1.4 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.
