Weblate Doesn't Invalidate API Token on Password Change

  • Disclosed: 30.04.2026
  • Updated: 11.10.2026 14:17

Impact

When a user changes their password, browser sessions are correctly invalidated via cycle_session_keys(), but DRF API tokens (wlu_* prefix) stored in authtoken_token are not revoked.
