What the vulnerability does
The Countdown Timer for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'countdown_label' Parameter in all versions up to, and including, 1.3.9 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
Countdown Timer for Elementor versions up to 1.3.9 contain a stored cross-site scripting (XSS) vulnerability. An authenticated user with low privileges can inject malicious scripts into timer settings that execute in the browsers of other site visitors. The vulnerability affects the entire site scope due to how Elementor renders the component.
What an attacker can do
Inject malicious JavaScript that runs in visitors' browsers and steals data or performs actions on their behalf.
Potential impact on your site
Visitors to pages with affected countdown timers may have their sessions hijacked, credentials stolen, or be redirected to malicious sites.
Conditions required to exploit
