Deeper analysis
CVE-2025-26579 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the videowhisper MicroPayments paid-membership WordPress plugin. This issue affects all versions of the plugin from n/a through 3.2.4 inclusive. The vulnerability was published on 2025-03-26 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).
Attackers can exploit this vulnerability remotely over the network with low attack complexity and no required privileges, though it requires user interaction such as clicking a malicious link. Exploitation enables reflected XSS, allowing attackers to inject and execute arbitrary scripts in the context of the victim's browser on the affected site, with a changed scope. This results in low impacts on confidentiality, integrity, and availability, potentially enabling session hijacking or other client-side attacks against interacting users.
