Descriptions

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in CoolHappy The Events Calendar Countdown Addon allows Stored XSS. This issue affects The Events Calendar Countdown Addon: from n/a through 1.4.9.

The The Events Calendar Countdown Addon plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 1.4.9 due to insufficient input sanitization and output escaping. 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.
