CVE-2025-9850 (GCVE-0-2025-9850)

Vulnerability from cvelistv5 – Published: 2025-09-11 07:24 – Updated: 2025-09-11 14:40

Title

Evenium <= 1.3.11 - Authenticated (Contributor+) Stored Cross-Site Scripting

Summary

The Evenium plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'evenium_single_event' shortcode in all versions up to, and including, 1.3.11 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.

Severity ?

6.4 (Medium)
