CVE-2026-1559

Name of the Vulnerable Software and Affected Versions Youzify versions prior to 1.3.7

Description The Youzify plugin for WordPress contains a Stored Cross-Site Scripting issue caused by insufficient input sanitization and output escaping. Authenticated attackers with Subscriber-level access or higher can inject arbitrary web scripts through the checkin place id parameter. These scripts execute whenever a user visits the affected page.

Recommendations Update the plugin to a version later than 1.3.6. As a temporary workaround, restrict the use of the checkin place id parameter to minimize the risk of exploitation.
