The Sina Extension for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. This affects the Sina Posts, Sina Blog Post, and Sina Table widgets in all versions up to 3.7.0. Authenticated attackers with Contributor-level privileges or higher can inject arbitrary scripts that execute in the context of users visiting the compromised pages. The vulnerability has a CVSS 3.1 base score of 6.4, reflecting network attack vector, low attack complexity, privileges required, no user interaction, and impacts on confidentiality and integrity but not availability. No vendor advisory or patch information is provided, and no known exploits have been reported.

Successful exploitation allows an authenticated user with Contributor or higher privileges to inject and store malicious scripts that execute in the browsers of users who view the affected pages. This can lead to unauthorized actions performed on behalf of users, data theft, or session hijacking. The impact affects confidentiality and integrity but does not affect availability. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider removing or disabling the affected widgets (Sina Posts, Sina Blog Post, Sina Table) to reduce risk. Monitor for updates from the plugin vendor regarding patches or official mitigations.
