CVE-2026-27838 · wger: IDOR via user-unscoped cache keys on routine API actions exposes workout data

This page contains facts from public vulnerability sources. Check the original advisory before updating.

wger is a free, open-source workout and fitness manager. Five routine detail action endpoints check a cache before calling `self.get_object()`. In versions up to and including 2.4, ache keys are scoped only by `pk` — no user ID is included. When a victim has previously accessed their routine via the API, an attacker can retrieve the cached response for the same PK without any ownership check. Commit e964328784e2ee2830a1991d69fadbce86ac9fbf contains a patch for the issue.
