# Installation
|
||||
|
||||
> [!CAUTION]
|
||||
> NOT for production use. This is just a side project (and also the first release), and it likely contains some bugs. DO NOT open ports to the internet (e.g. CORS is set to allow all)
|
||||
> NOT for production use. While attempts have been made at hardening (XSS/dompurify, CORS, rate-limiting, sanitization) have been made, they are inadequate for public deployment. Do not expose any ports. Currently lacking CSRF.
|
||||
|
||||
> [!CAUTION]
|
||||
> ExcaliDash is in BETA. Please backup your data regularly (e.g. with cron).

# ExcaliDash v0.1.5
|
||||
|
||||
Date: 2025-11-23
|
||||
|
||||
Compatibility: v0.1.x (Backward Compatible)
|
||||
|
||||
# Security
|
||||
|
||||
- RCE: implemented strict Zod schema validation and input sanitization on file uploads; added path traversal guards to file handling logic
|
||||
|
||||
- XSS: used DOMPurify for HTML sanitization; blocked execution-capable SVG attributes and enforces CSP headers.
|
||||
|
||||
- DoS: moved CPU-intensive operations to worker threads to prevent event loop blocking; request rate limiting (1,000 req/15 min per IP) and streaming for large files
|
||||
|
||||
# Infras & Deployment
|
||||
|
||||
- non-root execution (uid 1001) in containers
|
||||
- migrated to multi-stage Docker builds
|
||||
|
||||
# Database
|
||||
|
||||
- migrated to better-sqlite3, converted all DB interactions to non-blocking async operations and offloaded integrity checks to worker threads.
|
||||
|
||||
- implemented SQLite magic header validation; added automatic backup triggers preceding data import
|
||||
|
||||
- input validation logic
|
||||
|
||||
