{"cve":"CVE-2026-43976","nvd":{"published":"2026-10-07T14:17:09.887","modified":"2026-10-07T18:17:20.770","status":"Deferred","description":"wger is a free, open-source workout and fitness manager. 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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-863"],"references":["https://github.com/wger-project/wger/releases/tag/2.6","https://github.com/wger-project/wger/security/advisories/GHSA-c72h-82w6-rqfp","https://github.com/wger-project/wger/security/advisories/GHSA-c72h-82w6-rqfp"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-43976","score":0.00219,"percentile":0.12328,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-c72h-82w6-rqfp","url":"https://osv.dev/vulnerability/GHSA-c72h-82w6-rqfp","summary":"wger: cross-tenant admin notes/contracts leak via gym=None bypass (5 views)","modified":"2026-10-15T14:56:02.664228056Z","packages":[{"ecosystem":"PyPI","name":"wger","purl":"pkg:pypi/wger","ranges":["<=2.1"],"fixed":[]}]},{"id":"PYSEC-2026-4313","url":"https://osv.dev/vulnerability/PYSEC-2026-4313","summary":"wger: cross-tenant admin notes/contracts leak via gym=None bypass (5 views)","modified":"2026-10-15T14:45:10.349862114Z","packages":[{"ecosystem":"PyPI","name":"wger","purl":"pkg:pypi/wger","ranges":["<=2.1"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
