CVE-2023-32591: 
WordPress vulnerability analysis and mitigation

A Stored Cross-Site Scripting (XSS) vulnerability was discovered in Cloud Primero B.V DBargain WordPress plugin versions 3.0.0 and below. The vulnerability was identified on May 12, 2023, and requires administrator or higher privileges to exploit (Patchstack).

The vulnerability occurs because the plugin does not properly sanitize and escape some of its settings, 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 (NVD, WPScan).

If exploited, this vulnerability could allow malicious actors with administrative privileges to inject malicious scripts, such as redirects, advertisements, and other HTML payloads into the website. These scripts would then be executed when guests visit the affected site (Patchstack).

The vulnerability has been fixed in version 4.0.0 of the DBargain plugin. Users are advised to update to version 4.0.0 or later to remove the vulnerability. Patchstack users can enable auto-update for vulnerable plugins as an additional security measure (Patchstack).
