Summary

The Social Slider Feed plugin for WordPress from themeisle is affected in all versions up to and including 2.3.8. Insufficient input sanitization and output escaping of the slidespeed parameter enables stored cross-site scripting (CWE-79). An authenticated attacker with Subscriber-level access can inject scripts that run whenever a user views a page with the feed. A missing capability check also lets Subscriber users overwrite feed settings.

Description from the CNA

The Social Slider Feed – Social Media Feed & Gallery Widgets plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'slidespeed' parameter in all versions up to, and including, 2.3.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The missing current_user_can() check in the Factory framework's connect() dispatcher allows Subscriber-level users to bypass the manage_options capability gate and both harvest a valid wis_edit_feed nonce and overwrite any feed's slidespeed setting, after which the stored payload fires on every public pageview embedding the feed shortcode.
