Deeper analysis

CVE-2026-25352 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as CWE-79, enabling Reflected Cross-site Scripting (XSS) in the skygroup MyDecor WordPress theme. This issue affects MyDecor versions from n/a through those prior to 1.5.9. Published on 2026-03-25, it 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), indicating high severity due to network accessibility, low complexity, no required privileges, user interaction, and changed scope with low impacts across confidentiality, integrity, and availability.

Remote attackers without privileges can exploit this vulnerability by crafting malicious inputs that reflect unsanitized user-supplied data in web page generation, tricking victims into interacting via phishing links or similar vectors. Successful exploitation executes arbitrary JavaScript in the victim's browser context, potentially leading to session hijacking, data theft, or further site compromise, though impacts remain low per the CVSS metrics.

The Patchstack advisory recommends updating the MyDecor theme to version 1.5.9 or later, where the reflected XSS vulnerability is addressed. No other mitigations are specified in available references.
