Deeper analysisAI
CVE-2025-67949 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as CWE-79, enabling Reflected Cross-Site Scripting (XSS) in the Hostiko WordPress theme developed by designingmedia. This flaw affects all versions of the Hostiko theme from n/a through those prior to 94.3.6. The vulnerability 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 its network accessibility, low attack complexity, lack of required privileges, and scope change despite requiring user interaction and low individual impacts on confidentiality, integrity, and availability.
Remote attackers without privileges can exploit this vulnerability by crafting malicious payloads delivered via network-accessible inputs, such as URLs, that trick authenticated users into interacting with them, for example by clicking a link. Successful exploitation results in reflected XSS execution within the victim's browser context, potentially allowing attackers to steal session cookies, perform actions on behalf of the user, or deface pages, with impacts spanning low confidentiality, integrity, and availability effects elevated by the cross-origin scope change.
The Patchstack advisory for this WordPress theme vulnerability recommends updating the Hostiko theme to version 94.3.6 or later, where the issue is addressed. No additional mitigations are detailed in the provided reference.
