CVE-2023-45832: 
WordPress vulnerability analysis and mitigation

A Stored Cross-Site Scripting (XSS) vulnerability was discovered in Martin Gibson's WP GoToWebinar WordPress plugin versions 14.45 and below. The vulnerability was identified on October 13, 2023, and requires administrator or higher privileges to exploit (Patchstack).

The vulnerability is classified as a Stored Cross-Site Scripting (XSS) issue (CWE-79) that affects authenticated users with admin privileges. The CVSS v3.1 base score is 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. The vulnerability exists because the plugin does not properly validate and escape certain parameters, allowing privileged users to perform Stored XSS attacks even when the unfiltered_html capability is disallowed, such as in multisite setups (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 be executed when guests visit the affected site (Patchstack).

The vulnerability has been patched in version 14.46 of the WP GoToWebinar plugin. Users are advised to update to version 14.46 or later to remove the vulnerability. Patchstack users can enable auto-update for vulnerable plugins as an additional security measure (Patchstack).
