The GS Logo Slider WordPress plugin versions before 3.3.8 contains a stored Cross-Site Scripting (XSS) vulnerability identified as CVE-2022-4624. The vulnerability was discovered and disclosed on December 29, 2022, affecting the plugin's shortcode functionality. The issue allows users with contributor-level privileges or higher to perform stored XSS attacks that could potentially target high-privilege users such as administrators (WPScan).

The vulnerability stems from improper validation and escaping of shortcode attributes before they are output back to the page. The CVSS v3.1 base score is 5.4 (MEDIUM) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N. The vulnerability is classified as CWE-79: Cross-Site Scripting and falls under the OWASP Top 10 category A7: Cross-Site Scripting (XSS) (NVD, WPScan).

The vulnerability allows attackers with contributor-level access to inject malicious JavaScript code that executes in the context of other users' browsers, including administrators. This could potentially lead to unauthorized actions being performed with administrator privileges and access to sensitive information (WPScan).

The vulnerability has been fixed in version 3.3.8 of the GS Logo Slider plugin. Users are advised to update to this version or later to mitigate the risk (WPScan).
