{"id":"CVE-2026-46438","published":"2026-10-07T14:17:10.650","lastModified":"2026-10-07T19:17:37.280","description":"wger is a free, open-source workout and fitness manager. Prior to version 2.6, an authenticated attacker can inject arbitrary workout log entries into any other user's `SlotEntry` by supplying the victim's `slot_entry` ID in a `POST /api/v2/workoutlog/` request. The `slot_entry` foreign key is not included in the ownership verification performed by `WorkoutLogViewSet.get_owner_objects()`, so the server accepts and persists the cross-user reference without error. Because `SlotEntry.get_config_data()` retrieves associated logs via `self.workoutlog_set.all()` with no user filter, the attacker's injected data is silently folded into the victim's progressive-overload calculations, corrupting their auto-generated weight and repetition targets. Version 2.6 contains a patch.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","cwes":["CWE-639","CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/wger-project/wger/releases/tag/2.6","tags":[]},{"url":"https://github.com/wger-project/wger/security/advisories/GHSA-rjpf-7pf5-q54x","tags":[]},{"url":"https://github.com/wger-project/wger/security/advisories/GHSA-rjpf-7pf5-q54x","tags":[]}],"exploitRefs":[{"url":"https://github.com/wger-project/wger/releases/tag/2.6","tags":[]},{"url":"https://github.com/wger-project/wger/security/advisories/GHSA-rjpf-7pf5-q54x","tags":[]},{"url":"https://github.com/wger-project/wger/security/advisories/GHSA-rjpf-7pf5-q54x","tags":[]}],"hasPoc":true,"ai":null}
