What the vulnerability does
The Runners Log plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'runnerslog' shortcode in all versions up to, and including, 3.9.2 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
Runners Log versions 3.9.2 and earlier contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has a changed scope, meaning the impact can extend beyond the vulnerable component itself. An attacker with low-level account access can craft input that executes in other users' browsers, potentially compromising their sessions or data.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and affect the broader application.
Potential impact on your site
Authenticated users can inject scripts affecting other users and the application scope; update immediately to patch.
Conditions required to exploit
Attacker must have a low-privilege account on the site; no user interaction required from the victim.
