What the vulnerability does
The Eulerpool Research Systems plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'aaq' shortcode in all versions up to, and including, 4.0.1 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
Eulerpool Research Systems versions 4.0.1 and earlier contain a cross-site scripting vulnerability that allows an authenticated attacker to inject malicious scripts affecting other users or the application's integrity. The vulnerability has a changed scope, meaning the impact extends beyond the vulnerable component itself. Low-privileged users can exploit this without user interaction.
What an attacker can do
Inject malicious scripts that affect other users or modify application data.
Potential impact on your site
Authenticated users can inject scripts affecting other users' sessions or data integrity.
Conditions required to exploit
Attacker must have a low-privilege account; no user interaction required.
