What the vulnerability does
The WS Theme Addons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's ws_weather shortcode in all versions up to, and including, 2.0.0 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
WS Theme Addons versions 2.0.0 and earlier contain a cross-site scripting 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. Low-privileged users can exploit this without user interaction to compromise site integrity and access sensitive information.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and compromise site data.
Potential impact on your site
Authenticated users can inject scripts affecting other visitors and administrators, risking credential theft and site defacement.
Conditions required to exploit
Attacker must have a low-privilege account on the site; no user interaction required.
