Deeper analysis

CVE-2025-23599 is an Improper Neutralization of Input During Web Page Generation vulnerability, enabling Reflected Cross-site Scripting (XSS) as classified under CWE-79. It affects the eMarksheet WordPress plugin developed by Aarvansh Infotech, with the issue present in all versions from n/a through 5.4.3.

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). Remote attackers require no privileges and can exploit it over the network with low complexity by tricking users into performing an action, such as clicking a malicious link containing a reflected payload. Successful exploitation executes arbitrary scripts in the victim's browser context, potentially leading to low impacts on confidentiality, integrity, and availability, with scope change allowing effects beyond the vulnerable component, such as session-based attacks.
