## Affected

- wpdatatables wpDataTables – WordPress Data Table, Dynamic Tables & Table Charts Plugin: through 6.5.0.4

## Description

The wpDataTables – WordPress Data Table, Dynamic Tables & Table Charts Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 6.5.0.4. This is due to insufficient input sanitization and output escaping in the prepareCellOutput() method of the LinkWDTColumn, ImageWDTColumn, and EmailWDTColumn classes. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page, given that they can trick an Administrator into importing data from an attacker-controlled source and the affected column types (Link, Image, or Email) are configured.
