Can you explain this vulnerability to me?
The BJ Lazy Load plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in its filter_images() function in all versions up to and including 1.0.9.
This vulnerability arises because the plugin uses regex-based HTML processing (preg_replace) that does not correctly handle HTML attribute boundaries when replacing src attributes.
As a result, crafted content inside a class attribute value can be promoted to real DOM attributes after processing, allowing attackers to inject arbitrary web scripts.
Authenticated attackers with Contributor-level access or higher can exploit this to inject scripts that execute whenever a user accesses the injected page.
How can this vulnerability impact me? :
This vulnerability allows attackers with Contributor-level access or above to inject malicious scripts into pages.
These scripts execute in the context of users who visit the infected pages, potentially leading to theft of user data, session hijacking, or other malicious actions.
Because the vulnerability is a Stored Cross-Site Scripting issue, the injected scripts persist on the site and affect all users who view the compromised content.
