Can you explain this vulnerability to me?
The vulnerability exists in the Image Source Control Lite – Show Image Credits and Captions plugin for WordPress, specifically in all versions up to and including 3.9.1. It is a Stored Cross-Site Scripting (XSS) vulnerability that occurs via the 'Image Source' attachment field. This happens because the plugin does not properly sanitize input or escape output, allowing authenticated users with Author-level access or higher to inject arbitrary web scripts. These scripts execute whenever any user accesses a page containing the injected content.
How can this vulnerability impact me? :
This vulnerability can allow attackers with Author-level access or higher to inject malicious scripts into pages viewed by other users. These scripts can execute in the context of the victim's browser, potentially leading to theft of sensitive information, session hijacking, or performing actions on behalf of the victim without their consent. Since the vulnerability is a Stored Cross-Site Scripting, the malicious code persists on the site and affects all users who visit the infected pages.
