What the vulnerability does
The Omnipress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 1.6.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.
Explanation of Vulnerability in Simple Terms
Omnipress versions up to 1.6.5 contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has changed scope, meaning injected code can affect other users and site functionality beyond the vulnerable component. An attacker with low-level account access can craft malicious input that executes in other users' browsers, potentially stealing session data or performing unauthorized actions.
What an attacker can do
Inject malicious JavaScript that runs in other users' browsers and affects site functionality.
Potential impact on your site
Authenticated users can inject scripts affecting other visitors and site operations; update immediately to 1.6.6 or later.
Conditions required to exploit
Attacker must have a low-privilege account on the site; no user interaction required.
