MEDIUM

The Events Calendar <= 6.13.2 - Authenticated Stored Cross-Site Scripting via Data-Date Parameters

Title source: llm

Description

The The Events Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘data-date-*’ parameters in all versions up to, and including, 6.13.2 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.
