WordPress vulnerability analysis and mitigation

A Cross-site Scripting (XSS) vulnerability has been identified in AndonDesign UDesign Core (u-design-core) WordPress plugin affecting versions through 4.14.0. The vulnerability was discovered and disclosed on October 22, 2025, and received a CVSS v3.1 base score of 7.1 (High) (NVD, AttackerKB).

The vulnerability is classified as CWE-79: Improper Neutralization of Input During Web Page Generation, specifically manifesting as a Reflected XSS vulnerability. The CVSS vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L) indicates that the vulnerability can be exploited remotely with low attack complexity, requires no privileges but does need user interaction, and has a changed scope with low impacts on confidentiality, integrity, and availability (NVD).

The vulnerability allows attackers to execute reflected cross-site scripting attacks, potentially leading to unauthorized access to user data, session hijacking, or manipulation of web content. The changed scope and low impact ratings across confidentiality, integrity, and availability suggest that while the vulnerability is serious, its direct impact is somewhat limited (AttackerKB).

Users are advised to update their UDesign Core plugin to a version newer than 4.14.0 when available. As this is a recently discovered vulnerability, users should monitor the plugin developer's announcements for security patches (Patchstack).
