Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-43976 exists.\n\nAffected packages and fixed versions:\n- wger (PyPI): affected all versions up to 2.1; no fix listed\n- wger (PyPI): affected all versions up to 2.1; no fix listed\n- wger (PyPI): affected all versions up to 2.1; no fix listed\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-43976/ (Markdown: https://insights.sbomify.com/CVE-2026-43976/index.md)","id":"CVE-2026-43976","markdown":"https://insights.sbomify.com/CVE-2026-43976/index.md","name":"CVE-2026-43976","record":{"aliases":["GHSA-c72h-82w6-rqfp","PYSEC-2026-4313"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"wger fitness manager","requires_auth":"low_privilege","summary":"Trainers without gym assignment can bypass access controls to read private admin notes, contracts, and user data for any user on the instance.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"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.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"wger: cross-tenant admin notes/contracts leak via gym=None bypass (5 views)","id":"CVE-2026-43976","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":3,"n_references":2,"next":{"headline":"wger IDOR: Authenticated Users Can Read Others' Private Workout Session Data via Template Routine API","id":"CVE-2026-43977"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["2.1"],"package":"wger","purl":null,"source":"GHSA-c72h-82w6-rqfp"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["2.1"],"package":"wger","purl":"pkg:pypi/wger","source":"GHSA-c72h-82w6-rqfp"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["2.1"],"package":"wger","purl":"pkg:pypi/wger","source":"PYSEC-2026-4313"}],"prev":{"headline":"Apache Wicket: Possible malicious path traversal in FolderUploadsFileManager","id":"CVE-2026-43975"},"products":["wger"],"published":"2026-10-07","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-07","vendors":["wger-project"]},"summary":"Trainers without gym assignment can bypass access controls to read private admin notes, contracts, and user data for any user on the instance.","url":"https://insights.sbomify.com/CVE-2026-43976/"}
