Prior to version 2.6, five gym management views in wger apply a flawed gym-scope guard (`gym_a != gym_b`) that silently passes when both operands are `None`. A trainer with `gym.gym_trainer` and `gym.add_adminusernote` permissions and no gym assignment (`gym=None`) can read private admin notes, uploaded documents, gym contracts, user configuration, and user permission data for **any other unaffiliated user** on the instance. The subsequent querysets filter only on the attacker-supplied `member_id` with no secondary gym-scoped validation, so all records are disclosed. Version 2.6 fixes the issue.","state":0,"publishedAt":"2026-10-07T13:33:11.008+00:00","modifiedAt":"2026-10-07T17:26:56.782+00:00","affected":[{"ecosystem":"Vendor product","name":"wger","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"wger-project\",\n                    \"product\": \"wger\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.6\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","score":7.1,"severity":"HIGH"}],"references":["https://github.com/wger-project/wger/security/advisories/GHSA-c72h-82w6-rqfp","https://github.com/wger-project/wger/releases/tag/2.6"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-43976","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-43976","identifiers":["CVE-2026-43976"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
