AI-suggested

This vulnerability is fixed in wger version 2.6. Users should upgrade to version 2.6 or later to remediate this issue. Since this is not a cloud service, remediation depends on user action to update the software.

Description

wger is a free, open-source workout and fitness manager. Prior to 2.6, the reset_user_password and gym_permissions_user_edit 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.manage_gym 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.
