Stored Cross-Site Scripting Vulnerability in Calendar Plugin for WordPress

CVE-2025-14548

What is CVE-2025-14548?

The Calendar plugin for WordPress suffers from a Stored Cross-Site Scripting vulnerability in the 'event_desc' parameter. This issue arises due to inadequate input sanitization and output escaping, allowing authenticated attackers with Contributor-level access and above to inject malicious web scripts. Such scripts may be executed whenever a user accesses a page that has been compromised. The risk increases if an administrator grants lower privilege users permissions to manage calendar events through the plugin's settings. This vulnerability highlights the essential need for proper input validation and output encoding to safeguard user interactions.
