What is CVE-2026-119073?

The Live Composer plugin for WordPress prior to version 2.1.23 is vulnerable to a stored Cross-Site Scripting (XSS) attack. The vulnerability arises due to the lack of proper escaping of pagination settings supplied through shortcodes in its post-listing module. This weakness permits users with Contributor privileges and above to insert malicious scripts into web pages, potentially compromising user data and exploiting site visitors. Proper input validation and data sanitization measures need to be adopted to mitigate this vulnerability.

Affected Version(s)

Live Composer 0 < 2.1.23

Exploit Proof of Concept (PoC)
