This vulnerability (CVE-2026-65539) affects Kwayy HTML Sitemap versions up to 4.0 and is classified as CWE-352 (Cross-Site Request Forgery). It allows an attacker to perform unauthorized actions on behalf of an unauthenticated user by exploiting the lack of proper CSRF protections. The CVSS 3.1 base score is 7.1, indicating high severity, with network attack vector, low attack complexity, no privileges required, user interaction required, and scope changed. The impact includes low confidentiality, integrity, and availability impacts. No patch or official remediation level has been disclosed as of the publication date.

Successful exploitation of this vulnerability can allow an attacker to induce a victim to perform unwanted actions on the affected application without authentication. This can result in partial compromise of confidentiality, integrity, and availability of the system. However, the impact is limited to the extent described by the CVSS vector, indicating low-level data and system impact.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider implementing manual CSRF protections such as verifying origin headers or using anti-CSRF tokens if possible. Monitor vendor channels for updates.
