Deeper analysis

CVE-2025-23723 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (CWE-79), in the Plestar Directory Listing WordPress plugin. The flaw affects all versions of the plugin from n/a through 1.0 inclusive, enabling attackers to inject malicious scripts into dynamically generated web pages.

The vulnerability carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating exploitation is possible over the network with low attack complexity, no required privileges, and user interaction such as clicking a malicious link. Attackers can leverage reflected XSS to execute scripts in the context of a victim's browser, potentially leading to limited impacts on confidentiality, integrity, and availability with a changed scope.
