Unauthenticated data access and deletion via REST APIs

Published Apr 26, 2026 · Updated Apr 26, 2026

Missing authentication in 666ghj MiroFish 0.1.0 through 0.1.2 allows remote attackers to read or delete project data via REST APIs. The create_app factory registers graph, simulation, and report blueprints without authentication middleware or per-route checks. Any client that can reach the backend API can list sensitive project and report data, delete stored files, or interrupt simulations.
