{"id":"CVE-2026-35165","summary":"LORIS has incorrect access checks in document_repository","details":"LORIS (Longitudinal Online Research and Imaging System) is a self-hosted web application that provides data- and project-management for neuroimaging research. From 21.0.0 to before 27.0.3 and 28.0.1, while the document_repository frontend was restricting file access, the backend endpoint was not correctly verifying access permissions. A user could theoretically download a file that they should not have access to, if they know or can brute force the filename. This vulnerability is fixed in 27.0.3 and 28.0.1.","aliases":["GHSA-qp6x-qfx7-54wp"],"modified":"2026-08-12T03:51:24.883404871Z","published":"2026-04-08T18:23:34.101Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35165.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35165.json"},{"type":"ADVISORY","url":"https://github.com/aces/Loris/security/advisories/GHSA-qp6x-qfx7-54wp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35165"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/aces/loris","events":[{"introduced":"1abf7fc3858a96b494bd1ef83698fa1900f64eb8"},{"fixed":"f57f54b42a076bf53ba86e20d4dbf37f63538f58"},{"introduced":"83141ca814d2b8bda0e483589b726ea27f6ed4f7"},{"fixed":"c9bb7c87b405b4e0892cda25ab5fc791bcd562f4"}],"database_specific":{"extracted_events":[{"introduced":"21.0.0"},{"fixed":"27.0.3"},{"introduced":"28.0.0"},{"fixed":"28.0.1"}],"source":"AFFECTED_FIELD"}}],"versions":["28.0.0","v28.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-35165.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L"}]}
