Summary

wger: cross-tenant password reset and plaintext disclosure via gym=None bypass

Details

wger is a free, open-source workout and fitness manager. Prior to 2.6, the resetuserpassword and gympermissionsuseredit views in wger perform a gym-scope authorization check using Python object comparison (!=) that evaluates None != None as False, silently bypassing the guard when both the attacker and victim have no gym assignment (gym=None). A user with gym.managegym permission and gym=None can reset the password of any other gym=None user; the new plaintext password is returned verbatim in the HTML response body, enabling one-shot full account takeover. The victim's original password is invalidated, locking them out permanently. This vulnerability is fixed in 2.6.
