What the vulnerability does
Multiple plugins for WordPress are vulnerable to Stored Cross-Site Scripting via the plugin's bundled prettyPhoto library (version 3.1.6) in various versions due to insufficient input sanitization and output escaping on user supplied attributes. 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.
Explanation of Vulnerability in Simple Terms
Awesome WP Image Gallery versions 1.0 and earlier contain a stored cross-site scripting (XSS) vulnerability. An authenticated user with low privileges can inject malicious scripts that execute in the browsers of other site visitors, potentially compromising their sessions or stealing sensitive data. The vulnerability affects the site's scope, meaning impacts may extend beyond the gallery component itself.
What an attacker can do
Inject malicious scripts that run in other users' browsers when they view the gallery.
Potential impact on your site
Visitors' sessions and data could be compromised if a low-privilege user injects malicious code into the gallery.
Conditions required to exploit
Attacker must have a low-privilege authenticated account on the site.
