{"id":"CVE-2026-47230","summary":"Admidio: IDOR in documents-files.php allows cross-folder file rename and description changes by unauthorized uploaders","details":"Admidio is an open-source user management solution. Prior to version 5.0.10, `modules/documents-files.php` mode `file_rename_save` shares the same root-cause shape as the cross-folder move bug (`05-documents-cross-folder-move-idor.md`): the top-level rights check at lines 79-89 validates `hasUploadRight()` on the URL parameter `folder_uuid`, but the rename operation acts on `file_uuid` — a separate URL parameter — without re-checking the folder that actually contains the file. `DocumentsService::renameFile()` resolves the target file via `getFileForDownload()` (which permits view-readable files) but does not require upload right on the file's source folder. Result: a user with upload right on any folder A can rename a file in folder B as long as they can view it. They can also overwrite the file's description. Version 5.0.10 contains a fix.","aliases":["GHSA-q6w3-hpfv-rg36"],"modified":"2026-08-14T03:51:43.288216635Z","published":"2026-08-12T13:14:37.914Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-639","CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47230.json"},"references":[{"type":"ADVISORY","url":"https://github.com/Admidio/admidio/security/advisories/GHSA-q6w3-hpfv-rg36"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47230.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47230"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/admidio/admidio","events":[{"introduced":"0"},{"fixed":"8f7a2884e9dc9c51968046d9e6cbd6cb8fda46db"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"5.0.10"}]}}],"versions":["v5.0.9","v5.0.8","v5.0.7","v5.0.6","v5.0.5","v5.0.4","v34","v5.0.3","v5.0.2","v5.0.1","v5.0.0","v5.0-Beta.3","v5.0-Beta.2","v5.0-Beta.1","v4.3-Beta.1","v4.1-Beta.2","v4.0-Beta.1","v3.2-Beta.1","v3.1.5","v3.0.6","3.0-Beta.3","3.0-Beta.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-47230.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:N/I:H/A:N"}]}
