Prior to 2.6, the reset_user_password and gym_permissions_user_edit views in wger perform a gym-scope authorization check using Python object comparison (!=) that evaluates None != None as False, silently bypassing the guard when both the attacker and victim have no gym assignment (gym=None). A user with gym.manage_gym permission and gym=None can reset the password of any other gym=None user; the new plaintext password is returned verbatim in the HTML response body, enabling one-shot full account takeover. The victim's original password is invalidated, locking them out permanently. This vulnerability is fixed in 2.6.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9},"cwes":["CWE-863"],"references":["https://github.com/wger-project/wger/security/advisories/GHSA-mhc8-p3jx-84mm","https://github.com/wger-project/wger/security/advisories/GHSA-mhc8-p3jx-84mm"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-43948","score":0.00371,"percentile":0.31079,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-mhc8-p3jx-84mm","url":"https://osv.dev/vulnerability/GHSA-mhc8-p3jx-84mm","summary":"wger: cross-tenant password reset and plaintext disclosure via gym=None bypass","modified":"2026-06-29T12:26:41.642593311Z","packages":[{"ecosystem":"PyPI","name":"wger","purl":"pkg:pypi/wger","ranges":["<2.6"],"fixed":["2.6"]}]},{"id":"PYSEC-2026-574","url":"https://osv.dev/vulnerability/PYSEC-2026-574","summary":"wger: cross-tenant password reset and plaintext disclosure via gym=None bypass","modified":"2026-07-13T16:15:34.786211565Z","packages":[{"ecosystem":"PyPI","name":"wger","purl":"pkg:pypi/wger","ranges":["<2.6"],"fixed":["2.6"]}]}],"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).
