Security Summary

CVE-2025-23587 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, affecting the WordPress plugin all-in-one-box-login (also referred to as all-in-one-login) developed by Ashek Al Mahmud. The issue impacts all versions of the plugin from n/a through <= 2.0.1. It was published on 2025-03-03T14:15:43.437 and 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).

An unauthenticated attacker can exploit this vulnerability over the network with low attack complexity by crafting malicious input that is reflected and executed in a victim's browser upon user interaction, such as clicking a specially crafted link. Exploitation requires the victim to interact with the malicious payload, after which the attacker can achieve low impacts on confidentiality, integrity, and availability in a changed scope, potentially leading to session token theft or other client-side script execution within the context of the affected site.

Mitigation details are available in the Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/all-in-one-login/vulnerability/wordpress-all-in-one-box-login-plugin-2-0-1-reflected-cross-site-scripting-xss-vulnerability?_s_id=cve.
