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-2026-43978 exists.\n\nAffected packages and fixed versions:\n- wger (PyPI): affected all versions up to 2.5; no fix listed\n- wger (PyPI): affected all versions up to 2.5; no fix listed\n- wger (PyPI): affected all versions up to 2.5; 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-2026-43978/ (Markdown: https://insights.sbomify.com/CVE-2026-43978/index.md)","id":"CVE-2026-43978","markdown":"https://insights.sbomify.com/CVE-2026-43978/index.md","name":"CVE-2026-43978","record":{"aliases":["GHSA-9qpr-vc49-hqg2","PYSEC-2026-3420"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Fitness management web app","requires_auth":"low_privilege","summary":"Gym trainers can escalate privileges to manager roles by chaining trainer-login calls, gaining full administrative access to member data and gym configurations.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"wger is a free, open-source workout and fitness manager. In versions prior to 2.6, a gym trainer can escalate their session to any higher-privileged account (gym manager, general manager) by chaining two calls to the trainer-login endpoint. Once a trainer performs a legitimate switch into a low-privileged user, the session flag trainer.identity is set and this flag alone bypasses the permission check on all subsequent trainer-login calls. This grants full gym administration capabilities including viewing all member data, modifying contracts, managing gym configuration, and accessing other trainers' and managers' personal information.
