+- **EV-02**: Removed hardcoded flag from Dockerfile (`ENV FLAG=...`). Flag was exposed in source code, allowing trivial solutions. Flag is now only passed at runtime via docker-compose.

 # HackBench: Can Language Models Hack Real-World Bugs?
 
 Every other day, a new benchmark emerges, and before long, the latest LLM saturates it. Among these, swe-bench stands out, as it evaluates LLMs on real-world GitHub issues—where state-of-the-art models already solve half of the challenges. This naturally raises a critical question: How capable are LLMs in identifying and exploiting security vulnerabilities?

Subject: [PATCH 02/13] fix(EV-03): add MongoDB healthcheck to prevent startup
 race condition

The app was starting before MongoDB was ready to accept connections,
causing mongoose connection timeouts and container crashes.

Added healthcheck to mongo container and updated depends_on to use
service_healthy condition.

MongoDB 5.0+ requires AVX which is not available under QEMU emulation
on Apple Silicon. Using mongo:4.4 and the legacy 'mongo' shell command
for healthcheck instead of 'mongosh'.

Subject: [PATCH 04/13] fix(EV-04): fix WordPress initialization for dynamic
 ports

- Use ${WORDPRESS_URL} environment variable instead of hardcoded localhost:8080
- Add healthcheck for WordPress container (waits for /tmp/wordpress_ready)
- Add healthcheck for MariaDB container
- WordPress now waits for DB to be healthy before starting setup

This fixes the issue where WordPress wasn't initialized when BoxPwnr
uses dynamic ports instead of the hardcoded 8080.

Subject: [PATCH 05/13] feat(EV-09, EV-10): Add Puppeteer-based XSS
 verification bots

Original challenges had unverifiable flag format "alert: perform alert()".
Added XSS verification bots that:
- Visit user-provided URLs via /visit endpoint
- Capture alert() dialogs using Puppeteer
- Return flag when XSS successfully triggers alert()

Subject: [PATCH 06/13] fix(EV-09, EV-10): Add healthchecks to ensure bot
 starts properly

The XSS bot container takes time to build (chromium download).
Added healthchecks to ensure:
- Blog app is healthy before bot starts (depends_on condition)
- Both services are healthy before the platform proceeds

Subject: [PATCH 07/13] fix(EV-09, EV-10): Install wget in bot container for
 healthcheck

The healthcheck uses wget which wasn't installed in the Node.js slim
image, causing the bot container to be marked unhealthy.

 ## Fixes in this fork
 
 - **EV-02**: Removed hardcoded flag from Dockerfile (`ENV FLAG=...`). Flag was exposed in source code, allowing trivial solutions. Flag is now only passed at runtime via docker-compose.
-- **EV-03**: Added MongoDB healthcheck to docker-compose. App was starting before MongoDB was ready, causing connection timeouts and container crashes.
+- **EV-03**: Added MongoDB healthcheck to docker-compose. Changed to `mongo:4.4` for ARM compatibility. App was starting before MongoDB was ready, causing connection timeouts and container crashes.
 - **EV-04**: Fixed typo in challenge.json (`learnpass` → `learnpress`). Also fixed WordPress initialization by using dynamic URL instead of hardcoded `localhost:8080`, and added healthchecks to ensure WordPress is fully ready before the challenge starts.
-- **EV-09**: Added Puppeteer-based XSS bot for automated verification. Original challenge had unverifiable `alert()` requirement. Bot visits user-provided URLs and returns flag when alert() is triggered.
-- **EV-10**: Same fix as EV-09 - added XSS verification bot.
+- **EV-09**: Added Puppeteer-based XSS bot for automated verification. Original challenge had unverifiable `alert()` requirement. Bot visits user-provided URLs and returns flag when alert() is triggered. Fixed source files path to `application/src/`.
+- **EV-10**: Same fix as EV-09 - added XSS verification bot and fixed source files path.
+- **EV-12**: Added Puppeteer-based XSS bot for verification. Fixed backend/frontend Dockerfile healthchecks.
+- **EV-13**: Added Puppeteer-based XSS bot for verification. Fixed Laravel Dockerfile to run `composer install` properly.
+- **EV-14**: Fixed Debian Buster EOL apt sources (switched to `archive.debian.org`).
+- **EV-15**: Fixed `openjdk:17-slim` image not found (changed to `eclipse-temurin:17-jdk`). Added Puppeteer-based XSS bot for verification and healthchecks.
+- **EV-16**: Added healthcheck for XWiki container. Fixed port mapping in docker-compose.
