WordPress Plugin Vulnerabilities

EmbedStories < 0.7.5 - Contributor+ Stored XSS

Description

The plugin does not validate and escape some of its shortcode attributes before outputting them back in a page/post where the shortcode is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks

Proof of Concept

[embedsocial_stories id="' onmouseover='alert(1)' style='background:red;'"]

Affects Plugins

Fixed in 0.7.5
