CVE-2023-0146: 
WordPress vulnerability analysis and mitigation

The Naver Map WordPress plugin versions 1.1.0 and below contains a stored Cross-Site Scripting (XSS) vulnerability identified as CVE-2023-0146. The vulnerability was publicly disclosed on January 11, 2023. The plugin fails to properly validate and escape certain shortcode attributes before outputting them back in pages or posts where the shortcode is embedded (WPScan).

The vulnerability allows users with contributor role and above to perform Stored Cross-Site Scripting attacks through unvalidated shortcode attributes. A proof of concept exploit involves using the following shortcode: [naver-map y='" onmouseover="alert(1)" style="background:red;width:100px;height:100px;"']. The vulnerability has been assigned a CVSS score of 6.8 (medium) and is classified under CWE-79 (WPScan).

Successful exploitation of this vulnerability could allow authenticated users with contributor privileges or higher to inject and store malicious JavaScript code that would execute when other users view the affected pages. This could lead to theft of sensitive information, session hijacking, or other malicious actions performed in the context of the victim's browser (WPScan).

The vulnerability requires an authenticated user with at least contributor-level access to exploit. A working proof of concept exists demonstrating the vulnerability through manipulation of the naver-map shortcode parameters (WPScan).

No known fix has been released for this vulnerability. Site administrators should consider restricting access to the contributor role, reviewing and monitoring content submissions, or temporarily disabling the plugin until a security update is available (WPScan).
