{"cve":"CVE-2026-43977","nvd":{"published":"2026-07-16T23:16:16.167","modified":"2026-10-24T20:10:00.137","status":"Deferred","description":"wger is a free, open-source workout and fitness manager. In versions prior to 2.6, any authenticated user can read another user's private workout session notes, exercise history, and training statistics by calling the /logs/ and /stats/ actions on a routine they do not own. The vulnerability exists in RoutineViewSet (wger/manager/api/views.py). The view defines two custom actions /logs/ and /stats/ that are intended to return data for the requesting user's own training history within a routine. However, the underlying permission check (RoutinePermission.has_object_permission) grants read access to any authenticated user when the routine has is_template=True, regardless of ownership. When the /logs/ or /stats/ actions are invoked against a routine the attacker does not own, they return the owner's private workout history, not the attacker's. This issue has been fixed in version 2.6.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-639","CWE-863"],"references":["https://github.com/wger-project/wger/security/advisories/GHSA-cj9g-27ph-4cgv","https://github.com/wger-project/wger/security/advisories/GHSA-cj9g-27ph-4cgv"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-43977","score":0.00289,"percentile":0.21249,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-cj9g-27ph-4cgv","url":"https://osv.dev/vulnerability/GHSA-cj9g-27ph-4cgv","summary":"wger Vulnerable to IDOR: Authenticated Users Can Read Any User's Private Workout Session Data via Template Routine API","modified":"2026-07-13T16:42:42.391148979Z","packages":[{"ecosystem":"PyPI","name":"wger","purl":"pkg:pypi/wger","ranges":["<=2.5"],"fixed":[]}]},{"id":"PYSEC-2026-3421","url":"https://osv.dev/vulnerability/PYSEC-2026-3421","summary":"wger Vulnerable to IDOR: Authenticated Users Can Read Any User's Private Workout Session Data via Template Routine API","modified":"2026-07-13T16:33:32.436495369Z","packages":[{"ecosystem":"PyPI","name":"wger","purl":"pkg:pypi/wger","ranges":["<=2.5"],"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).
