This vulnerability in the Post Carousel Slider for Elementor plugin involves improper input sanitization during web page generation, leading to stored cross-site scripting (XSS). Attackers can inject malicious scripts that persist in the plugin's output, potentially impacting confidentiality, integrity, and availability to a limited extent. The issue affects all versions through 1.5.0. No patch or vendor advisory has been provided yet, and no known active exploitation has been reported.

Successful exploitation could allow an attacker with low privileges and requiring user interaction to execute arbitrary scripts in the context of the affected site. This could lead to limited confidentiality, integrity, and availability impacts as reflected in the CVSS vector. However, the impact is mitigated by the requirement for user interaction and low privileges.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider limiting plugin usage or applying temporary mitigations such as input validation or disabling the plugin if feasible.
