Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Frequent authorization and policy bypasses occurred because user identities, API tokens, and workspace-level permission layers were either bypassed, not synchronized during concurrent requests, or loaded in the incorrect middleware order.
Command Injection: Shell commands constructed via direct string interpolation or unsafely passed paths allowed command execution during provisioning, mount operations, and remote execution.
Path Traversal: Missing path canonicalization and failure to check for directory traversal structures in zip extractions and streaming downloads allowed arbitrary file reads and writes.
