CVE-2025-8561

Name of the Vulnerable Software and Affected Versions Ova Advent plugin for WordPress versions up to and including 1.1.7

Description The software contains a flaw due to insufficient input sanitization and output escaping on user-supplied attributes within the plugin’s shortcodes. This allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages. These scripts will execute when a user accesses the affected page.

Recommendations Update the Ova Advent plugin to a version newer than 1.1.7.
