{"id":"CVE-2026-55081","summary":"DHIS2 Reflected XSS in OpenAPI HTML scope parameter","details":"DHIS2 is a flexible information system for data capture, management, validation, analytics and visualization. The DHIS2 OpenAPI HTML endpoint reflected values from the `scope` query parameter into the generated HTML document without sufficient sanitization. A crafted `scope` value could be rendered as active HTML or JavaScript in the OpenAPI documentation page. An attacker able to get a user to open a crafted OpenAPI HTML URL could execute JavaScript in that user's browser in the DHIS2 origin.\n\nAffected versions: DHIS2 2.42 and 2.43 before the 2026-06-09 security patch releases, and the development branch for DHIS2 2.44 before the fix was merged.\nPatched in 2.42.5.1, 2.43.0.1, the 2.42 and 2.43 line branches, and the 2.44 development branch.","aliases":["GHSA-6785-hj47-c27h"],"modified":"2026-08-12T03:51:29.306384231Z","published":"2026-07-21T18:36:46.507Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55081.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55081.json"},{"type":"ADVISORY","url":"https://github.com/dhis2/dhis2-core/security/advisories/GHSA-6785-hj47-c27h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55081"},{"type":"FIX","url":"https://github.com/dhis2/dhis2-core/pull/24158"},{"type":"FIX","url":"https://github.com/dhis2/dhis2-core/pull/24159"},{"type":"FIX","url":"https://github.com/dhis2/dhis2-core/pull/24160"},{"type":"FIX","url":"https://github.com/dhis2/dhis2-core/pull/24161"},{"type":"FIX","url":"https://github.com/dhis2/dhis2-core/pull/24162"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dhis2/dhis2-core","events":[{"introduced":"4bc649ee714c0ec0e3cfeea32557252e9e22644f"},{"fixed":"9d7f88a940e6e5ee766767424306fb11cb4a1f2b"},{"introduced":"0c543cc7776403b5cd9345ed8bc8f82543fbefe5"},{"fixed":"58a531e163ddeefed47904841240ee436b247703"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"2.42.0"},{"fixed":"2.42.5.1"},{"introduced":"2.43.0"},{"fixed":"2.43.0.1"}]}}],"versions":["2.43.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-55081.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
