What the vulnerability does
The ConvertCalculator for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'id' and 'type' parameters in all versions up to, and including, 1.1.1 due to insufficient input sanitization and output escaping. 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
ConvertCalculator versions up to 1.1.1 contain a stored cross-site scripting (XSS) vulnerability. An authenticated user with low privileges can inject malicious scripts into calculator fields. When other users view the affected calculator, the injected code runs in their browser, potentially allowing the attacker to steal session tokens, redirect users, or modify page content. The vulnerability affects all users of the site.
What an attacker can do
Inject malicious scripts that execute in other users' browsers when they view a calculator.
Potential impact on your site
Authenticated users can compromise other users' sessions or steal sensitive data through injected scripts.
Conditions required to exploit
Attacker must be logged in with low-level user privileges; no user interaction required from victims.
