SEC-XSS-001. Chaine complete : un nom d'utilisateur libre arrivait dans le
DOM d'un coach ou d'un administrateur, en meme origine, avec sa session.
La CSP autorisant 'unsafe-inline', rien ne l'arretait.
Cote serveur - la cause
/matches/api/events construisait de la presentation dans un champ JSON :
match_desc = participants_str + f"<br>{match.description}"
Le navigateur deposait cette valeur telle quelle dans innerHTML. Les noms
de joueurs y transitaient sans echappement -- et il ne pouvait pas y en
avoir : c'est du JSON, pas du HTML.
Les deux valeurs etaient deja des cles distinctes du payload. La
concatenation faisait donc aussi afficher les participants deux fois dans
le modal : une fois dans "Teams", une fois en tete de "Description".
Corriger la faille corrige l'affichage.
Cote navigateur - le sink
showEventModal assemblait une chaine HTML puis l'affectait a innerHTML.
Remplace par une construction de noeuds : makeEl / detailItem /
multilineNode / teamNode passent tout texte par textContent. Les retours
a la ligne d'une description restent rendus, via des <br> crees en dur.
Les deux listes deroulantes concatenaient egalement titres de tryout et
noms d'equipe dans innerHTML. Remplacees par new Option(), dont le
premier argument est pose en texte.
Verification
5 tests sur le contrat de l'API, dont un avec un nom d'utilisateur
hostile ecrit directement en base -- ce que la validation refuse
desormais, mais que des lignes anterieures peuvent contenir.
Le JavaScript inline extrait passe `node --check`.
Reste ouvert : la CSP autorise toujours 'unsafe-inline' (SEC-WEB-001), donc
la defense en profondeur manque encore. Suivi en OPS-010.

Plateforme centralisée de tryouts
Security Configuration
Required Environment Variables
Before deploying, create a .env file which integrates everything in the .env.exemple.
Ensure you follow the comments of the exemple if you are to use this tool in production.
Security Features Implemented
- Rate Limiting: Login endpoint limited to 10 requests per minute to prevent brute-force attacks
- Secure Session Cookies: HTTPSOnly, SameSite=Lax, and Secure flags enabled
- CSRF Protection: Enabled by default on all forms
- HTTPS Enforcement: Automatic redirect to HTTPS in production
- Security Headers: X-Frame-Options, X-Content-Type-Options, Content-Security-Policy, HSTS
- Open Redirect Prevention: URL validation on login redirect
- Authorization Checks: Proper ownership validation on all sensitive operations
- nginx: reverse-proxy and load balancer
- Waitress WSGI: Production ready WSGI
When true in .env:
- Forces HTTPS only
- Forcer secure cookies
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
