From ab44258d72d5dda954cd74741fd0d3bd90d71e3f Mon Sep 17 00:00:00 2001 From: GGThed Date: Fri, 7 Aug 2026 20:01:24 -0400 Subject: [PATCH] feat(obs): journaliser les evenements d'authentification OBS-001. logging_config.py configurait un fichier auth.log avec rotation, un logger nomme 'team_tryouts.auth' et un filtre de redaction. Mais get_auth_logger n'etait importe nulle part : le fichier etait cree et restait vide. Aucune connexion, aucun echec, aucun verrouillage, aucun changement de role, aucune suppression de compte ne laissait de trace. En cas de suspicion de compromission, il n'y avait rien a consulter. Ajout de log_auth_event(event, **fields), qui emet des paires cle=valeur ordonnees -- greppable sans dependance de journalisation JSON. Evenements couverts authentification login.success, login.failure, login.failure.unknown_user, login.rejected.locked, login.rejected.deactivated, account.locked, logout, account.registered administration account.created_by_admin, account.updated, account.role_changed (avec ancien et nouveau role), account.deleted, account.password_reset_by_admin libre-service account.password_changed Le champ ip vient de request.remote_addr, donc de X-Forwarded-For. Tant que Waitress tourne avec trusted_proxy='*' (SEC-WEB-002), cette valeur est choisie par l'appelant : c'est une indication, pas une preuve. Le point est documente dans la docstring. Un test a fait remonter ARCH-003, jusqu'ici classe comme fragilite latente Journaliser en fin de edit_user levait DetachedInstanceError : le changement de role appelle db.session.remove() en plein cycle de requete, ce qui detache current_user de la session. Le code s'en tirait parce qu'il redirigeait immediatement sans plus y toucher. L'identite de l'acteur est desormais capturee en debut de traitement. Le constat est donc confirme comme reel, et non plus seulement probable -- sa correction de fond reste au programme. 15 tests, dont 4 sur le filtre de redaction lui-meme : c'est un controle de securite, il doit etre verifie.
