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.","state":0,"publishedAt":"2026-10-07T14:00:10.046+00:00","modifiedAt":"2026-10-07T18:00:21.494+00:00","affected":[{"ecosystem":"Vendor product","name":"wger","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"wger-project\",\n                    \"product\": \"wger\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.6\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/wger-project/wger/security/advisories/GHSA-rjpf-7pf5-q54x","https://github.com/wger-project/wger/releases/tag/2.6"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-46438","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-46438","identifiers":["CVE-2026-46438"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
