WordPress · Wordpress Calendar · CVE-2025-14548
**Name of the Vulnerable Software and Affected Versions**
WordPress Calendar plugin versions prior to 1.3.17
**Description**
The Calendar plugin for WordPress is susceptible to Stored Cross-Site Scripting. This is due to insufficient input sanitization and output escaping in the `event desc` parameter. Authenticated attackers with Contributor-level access or higher can inject arbitrary web scripts into pages. These scripts will execute when a user accesses the injected page, provided an administrator has enabled lower privilege users to manage calendar events through the plugin settings.
**Recommendations**
Update the Calendar plugin to version 1.3.17 or later.
