The PDF Viewer for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) in its render function in versions up to 2.9.3. This occurs due to improper neutralization of input during web page generation, allowing authenticated users with contributor or higher privileges to inject arbitrary web scripts. These scripts execute in the context of users viewing the injected pages, potentially leading to information disclosure or session hijacking. The CVSS 3.1 base score is 6.4 (medium), reflecting network attack vector, low attack complexity, and privileges required at the contributor level.

An attacker with contributor-level access or higher can inject malicious scripts that execute in the browsers of users who view the compromised pages. This can lead to limited confidentiality and integrity impacts, such as theft of user session data or manipulation of page content. There is no indication of availability impact. No known exploits are reported in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider removing or disabling the vulnerable plugin if possible. Monitor for updates from the vendor or WordPress plugin repository for a security update addressing this issue.
