CVE-2023-41655: 
WordPress vulnerability analysis and mitigation

A Stored Cross-Site Scripting (XSS) vulnerability was discovered in the Andreas Heigl authLdap WordPress plugin versions 2.6.1 and below. The vulnerability was identified on September 1, 2023, and affects users with administrator privileges. The issue was assigned CVE-2023-41655 and was reported by security researcher Rio Darmawan (Patchstack).

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation) and 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. Patchstack assigned a slightly higher CVSS score of 5.9 (Medium). The issue stems from the plugin's failure to properly validate and escape certain parameters, which could allow privileged users to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed, such as in multisite setups (WPScan).

The vulnerability could allow malicious actors with administrator 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 has been patched in version 2.6.2 of the authLdap plugin. Site administrators are advised to update to version 2.6.2 or later to remediate the security issue (Patchstack).
