Vulnerability Overview
The Timeline Widget For Elementor (Elementor Timeline, Vertical & Horizontal Timeline) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via image URLs in the plugin's timeline widget in all versions up to, and including, 1.5.3 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page, changes the slideshow type, and then changes it back to an image.
Technical Analysis
The vector marks this flaw as remotely reachable over the network.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Timeline Widget For Elementor (Elementor Timeline, Vertical & Horizontal Timeline) <= 1.5.3 takes an account at Contributor level or above. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Timeline Widget For Elementor (Elementor Timeline, Vertical & Horizontal Timeline) the fix is 1.5.4: builds <= 1.5.3 are affected, anything from 1.5.4 onward is not.
Remediation
Update to version 1.5.4, or a newer patched version
How does WordSec protect against this?
An attacker needs Contributor access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Timeline Widget For Elementor (Elementor Timeline, Vertical & Horizontal Timeline) 1.5.4 closes this, and updating the plugin is the step that ends it.
