WordPress vulnerability analysis and mitigation

CVE-2023-24002 is a Stored Cross-Site Scripting (XSS) vulnerability affecting WPdevart YouTube Embed, Playlist and Popup WordPress plugin versions 2.6.3 and below. The vulnerability was discovered on January 23, 2023, and requires administrator or higher privileges to exploit (Patchstack).

The vulnerability stems from improper sanitization and escaping of certain parameters in the plugin, which could allow high-privilege users such as administrators to perform Stored Cross-Site Scripting attacks, even when the unfiltered_html capability is disallowed (for example in multisite setup). The vulnerability has been assigned a CVSS v3.1 base score of 4.8 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N (WPScan).

The vulnerability could allow malicious actors with administrative access to inject malicious scripts, including redirects, advertisements, and other HTML payloads into the website. These injected scripts would then be executed when guests visit the affected site (Patchstack).

The vulnerability has been fixed in version 2.6.4 of the WPdevart YouTube Embed, Playlist and Popup plugin. Users are advised to update to version 2.6.4 or later to remove the vulnerability (Patchstack).
