## Affected

- dglingren Media Library Assistant: through 3.35

## Description

The Media Library Assistant plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'mla_link_attributes' parameter in all versions up to, and including, 3.35 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.
