CVE-2025-1511: 
WordPress vulnerability analysis and mitigation

The vulnerability CVE-2025-1511 affects the User Registration & Membership – Custom Registration Form, Login Form, and User Profile plugin for WordPress. The vulnerability was discovered and disclosed on February 28, 2025, and involves a Reflected Cross-Site Scripting (XSS) vulnerability via the 's' parameter in versions up to and including 4.0.4. This security flaw stems from insufficient input sanitization and output escaping in the plugin (NVD).

The vulnerability is classified as a CWE-79 (Improper Neutralization of Input During Web Page Generation) issue. It has received a CVSS v3.1 Base Score of 6.1 (Medium) with the following vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N. This scoring indicates that the vulnerability is network-accessible, requires low attack complexity, needs no privileges, but does require user interaction, and can have cross-origin impacts with low confidentiality and integrity consequences (NVD).

The vulnerability allows unauthenticated attackers to inject arbitrary web scripts into pages that will execute if they can successfully trick a user into performing specific actions, such as clicking on a malicious link. This could lead to potential compromise of user data and session information (NVD).

A patch has been released in version 4.1.0 of the plugin to address this vulnerability. Users are advised to update to this version or later to mitigate the risk (WordPress Patch).
