GHSA-rjpf-7pf5-q54x: wger (CVE-2026-46438)

Package	Ecosystem	Affected	Fixed in
wger	PyPI	<=2.1	No fixed version yet

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Wger versions up to and including 2.1 are affected. An authenticated user can create workout log entries that reference another user's slot entry, because the server's ownership check does not cover that field, and the injected entries are then included in the victim's progression calculations. The source describes the attacker needing only a slot entry ID and an account of their own, and says the victim gets no notification. The advisory lists no fixed version, but it proposes adding the slot entry to the ownership check and filtering logs by routine owner.
