{"id":"CVE-2026-27835","summary":"wger: IDOR in RepetitionsConfig and MaxRepetitionsConfig API leak other users' workout data","details":"wger is a free, open-source workout and fitness manager. In versions up to and including 2.4, `RepetitionsConfigViewSet` and `MaxRepetitionsConfigViewSet` return all users' repetition config data because their `get_queryset()` calls `.all()` instead of filtering by the authenticated user. Any registered user can enumerate every other user's workout structure. Commit 1fda5690b35706bb137850c8a084ec6a13317b64 contains a fix for the issue.","aliases":["GHSA-xf68-8hjw-7mpm","PYSEC-2026-3423"],"modified":"2026-08-12T03:51:24.806747669Z","published":"2026-02-26T22:00:23.768Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27835.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-639"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27835.json"},{"type":"ADVISORY","url":"https://github.com/wger-project/wger/security/advisories/GHSA-xf68-8hjw-7mpm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27835"},{"type":"FIX","url":"https://github.com/wger-project/wger/commit/1fda5690b35706bb137850c8a084ec6a13317b64"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wger-project/wger","events":[{"introduced":"0"},{"fixed":"1fda5690b35706bb137850c8a084ec6a13317b64"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:wger:wger:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"last_affected":"2.4"}]}}],"versions":["2.4","2.3","2.0","1.9","1.8","1.7","1.5","1.4","1.3","1.2","1.1","1.0.3","1.0.2","1.0.1","1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-27835.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:N/A:N"}]}
