CVE-2025-5559 Information

Description

The TimeZoneCalculator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin’s ’timezonecalculator_output’ shortcode in all versions up to and including 3.37 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.
