CVE-2023-25958: 
WordPress vulnerability analysis and mitigation

A Stored Cross-Site Scripting (XSS) vulnerability was discovered in the Justin Saad Simple Tooltips WordPress plugin versions 2.1.4 and below. The vulnerability was identified on February 17, 2023, and publicly disclosed on April 19, 2023. This security issue affects administrators and users with high privileges in WordPress installations (Patchstack).

The vulnerability occurs because the plugin fails to properly sanitize and escape some of its settings, which could enable high-privilege users such as administrators to perform Stored Cross-Site Scripting attacks, even in scenarios where the unfiltered_html capability is disabled, such as in multisite setups. The vulnerability has been assigned CVE-2023-25958 and has received a CVSS v3.1 base score of 4.8 (MEDIUM) from NIST with a vector string of CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N, while Patchstack assessed it with a score of 5.9 (MEDIUM) (NVD, 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 visitors access the affected site (Patchstack).

The vulnerability requires high privileges (administrator level access) to exploit, and user interaction is necessary for successful exploitation. The security issue has been classified as having a low severity impact and is considered unlikely to be exploited (Patchstack).

As of the latest reports, there is no official fix available for this vulnerability. The issue affects versions 2.1.4 and below of the Simple Tooltips plugin (WPScan).
