CVE-2025-9852: Momostefan Yoga Schedule Momoyoga

Medium severity, CVSS 6.4. EPSS: 0.2% chance of exploitation in the next 30 days.

The Yoga Schedule Momoyoga plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'momoyoga-schedule' shortcode in all versions up to, and including, 2.9.0 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.
