A Reflected Cross-Site Scripting (XSS) vulnerability was discovered in the YAS Global Team Permalinks Customizer WordPress plugin, affecting versions up to and including 2.8.2. The vulnerability was initially reported by Le Ngoc Anh on July 27, 2023, and was publicly disclosed on November 14, 2023. This security issue has been assigned CVE-2023-47773 and affects the plugin due to insufficient input sanitization and output escaping (Patchstack, WPScan).

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation) and has received varying CVSS scores from different sources. The National Vulnerability Database (NVD) assigned a CVSS v3.1 base score of 6.1 (Medium) with vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N, while Patchstack rated it at 7.1 (High) with vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L.

The vulnerability allows malicious actors to inject arbitrary web scripts that execute when users interact with compromised elements, such as clicking on a specially crafted link. This could lead to the injection of malicious scripts, potentially resulting in redirects, unauthorized advertisements, and other malicious HTML payloads being executed on the target website (Patchstack).

As of the latest reports, no official fix is available for this vulnerability. However, Patchstack has issued a virtual patch to mitigate the issue by blocking potential attacks until an official fix becomes available.
