Deeper analysis

CVE-2025-23505 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, affecting the Pit Login Welcome WordPress plugin (pit-login-welcome). This issue impacts all versions from n/a through 1.1.5, as disclosed on March 3, 2025, with 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 remote attacker can exploit this vulnerability over the network with low complexity by tricking an authenticated user into performing an action, such as clicking a malicious link. Exploitation changes the scope and enables execution of arbitrary scripts in the victim's browser context, resulting in low impacts to confidentiality, integrity, and availability.
