Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Sandbox Escape: Reactive objects sent across the Electron IPC boundary allowed escaping the sandbox. Safe serialization must be enforced for all payloads sent through the Electron API.
Path Traversal: The backup restoration feature used unzipSync without validating extracted target paths, leading to potential arbitrary file writes. Canonicalization and prefix verification are required on all archive extractions.
Prototype Pollution: Unvalidated key assignment allowed potential prototype pollution via magic properties such as __proto__. Strict key blocklisting is required when processing model parameter payloads.
