SEC-AUTH-004. L'URL d'autorisation ne portait que client_id, redirect_uri,
response_type et scope. Sans state, le callback acceptait n'importe quel
code d'autorisation qu'on lui presentait.
Scenario ferme : un attaquant obtient un code pour SON compte Discord, puis
fait charger l'URL de callback par le navigateur de la victime. Le
formulaire d'inscription de la victime se retrouve pre-rempli avec
l'identite Discord de l'attaquant. C'est le login CSRF decrit par la
RFC 6749 §10.12.
Mise en oeuvre
secrets.token_urlsafe(32) genere le jeton, stocke en session avant la
redirection. Le callback le compare en temps constant avec
secrets.compare_digest, et le consomme systematiquement -- valide ou non --
pour qu'il ne puisse pas etre rejoue. Le controle intervient avant
l'echange du code : un callback rejete ne declenche aucun appel reseau.
Deux corrections accessoires sur le meme chemin
- DISCORD_REDIRECT_URI est desormais verifie au meme titre que
DISCORD_CLIENT_ID. Non defini, il faisait lever requests.utils.quote(None)
au lieu de signaler un probleme de configuration.
- la construction de la chaine de requete passe a urlencode() plutot qu'a
une concatenation manuelle.
9 tests : presence du state, stockage en session, unicite entre deux
demandes, rejet sans state, avec un state forge, sans demande prealable,
et non-rejouabilite.
Reste ouvert : l'identite Discord obtenue reste ensuite reinjectee par un
champ cache du formulaire (SEC-AUTH-005). Le state protege la liaison, pas
encore la valeur elle-meme.

App details
Code
- Full python backend using flask
- statics are pure HTML and CSS
- Some js to add logic to styling and showing certain pages/cards
Functionalities
- User base with sign-ins: Forces users to create an account and register pertinent information for tryouts and teams. The admin can attribute them a role.
- User-Role-Based Permissions: admin - full acces, coach/manager - access to team management, player - views what he is registered in (no management), scout - view only
- Tryout Management: manage internal tryout teams, organise internal tryouts matches (3 formats, team vs team, PvP, scrim). Coaches can Evaluate players based on 10 criteria
- Team Management: manage teams for the season, create matches and practices. When planning a practice there will be a calendar showing player availabitlities slots to help chose a time
- Coach and Player Availabilities: Allow better planning for the coaches, and for players to book One on Ones with their coach.
- Player Notes: Coaches can give notes to their players. The players will see them and there is a history which keeps the most recent notes.
- Team Notes: Coaches can give notes to their teams, where all players from that team can see the note.
- One on One: Players can request a One on One meeting with their coach. This sends a discord dm to the coach to accept or refuse. The player is then notified of the response.
- Availabilities: Allow players and coach to enter the moments they are available. Allows for easier practice setup and One on One planning.
Discord Integration
The application supports sending Discord direct messages to coaches when players request One on One sessions, when matches/tryouts/practices are created and a player is in it, and the players get match reminders 24h before a match.
When sending a One on One request, the coach can accept via the platform or react to the discord message to answer the booking request. Same thing with matches and practices, the players can react or answer on the platform.
Setup Instructions
1. Create a Discord Bot (Not needed for UdeS user, the bot already exists)
- Go to the Discord Developer Portal
- Create a new application
- Go to the "Bot" tab and create a bot user
- Copy the bot token - this will be your
DISCORD_BOT_TOKEN - Enable the "Message Content Intent" under Privileged Gateway Intents (required for sending messages)
2. Add Bot to your server
For the bot to send DMs:
- Each user must have the bot added to their Discord server OR be friends with the bot
- Users need to add their Discord User ID to their profile:
- Enable Developer Mode in Discord (User Settings → Advanced → Developer Mode)
- Right-click on their profile → Copy ID
- Enter this numeric ID in the "Discord User ID" field in their profile settings
How It Works
When a player submits a One on One request:
- The system checks if the coach has a Discord User ID configured
- If configured, a direct message is sent to the coach via the Discord bot
Message Format
The Discord DM includes:
- Player name
- Team name
- Requested date and time slot
- Discussion points (if provided)
- Link to the application for approval/rejection
- Two provided reactions to accept or refuse via discord
