Description

The Event post plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 5.9.8 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.
