CVE-2026-55081: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in dhis2 dhis2-core
A cross-site scripting (XSS) vulnerability exists in the DHIS2 OpenAPI HTML endpoint where the 'scope' query parameter is reflected into the HTML output without proper sanitization. This allows an attacker to craft a URL that executes arbitrary JavaScript in the context of the DHIS2 web application. The issue affects DHIS2 versions 2.42, 2.43, and 2.44 before the June 9, 2026 security patches. Fixed versions include 2.42.5.1, 2.43.0.1, and the updated 2.44 development branch.
AI Analysis
Technical Summary
CVE-2026-55081 is a CWE-79 cross-site scripting vulnerability in the dhis2-core product. The vulnerability arises because the OpenAPI HTML endpoint reflects the 'scope' query parameter into the generated HTML document without sufficient input neutralization. An attacker can craft a malicious URL that, when visited by a user, executes JavaScript within the user's browser under the DHIS2 origin. This affects DHIS2 versions 2.42, 2.43, and 2.44 prior to the security patches released on 2026-06-09. The vulnerability has a CVSS 4.0 score of 7.3 (high severity).
Potential Impact
Successful exploitation allows an attacker to execute arbitrary JavaScript in the context of the DHIS2 web application for users who open a maliciously crafted OpenAPI HTML URL. This can lead to actions such as session hijacking, unauthorized actions on behalf of the user, or data theft within the scope of the affected DHIS2 instance.
Mitigation Recommendations
Security patches fixing this vulnerability were released on 2026-06-09 in versions 2.42.5.1, 2.43.0.1, and the updated 2.44 development branch. Users should upgrade to these patched versions to remediate the issue. No other mitigation or temporary workaround is specified.
