What the vulnerability does
The Easy Author Image plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'author_profile_picture_url' parameter in all versions up to, and including, 1.7 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.
Explanation of Vulnerability in Simple Terms
Easy Author Image versions 1.7 and earlier contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts affecting other users. The vulnerability exists because user-supplied input is not properly sanitized before being displayed. An attacker with low-level access can craft a malicious request that executes JavaScript in the browsers of other site visitors, potentially compromising their sessions or stealing sensitive data.
What an attacker can do
Inject and execute malicious JavaScript in other users' browsers to steal session data or perform actions on their behalf.
Potential impact on your site
Authenticated users can inject scripts that affect other visitors, risking account compromise and data theft across your site.
Conditions required to exploit
Attacker must have a low-privilege user account on the site; no user interaction required from victims.
