22,657 findings (99.8%) were not detected by Bandit or Semgrep. These include compound vulnerabilities, logic errors, and context-dependent security issues that rule-based scanners aren't designed to catch.
Notable Findings
CriticalSecurity
SQL Injection in Database Migrations
Impact: Alembic migration files contain direct SQL string concatenation, allowing potential SQL injection during schema updates.
Recommended Fix: Use parameterized queries or ORM methods. Replace raw SQL string formatting with prepared statements.
CriticalSecurity
35 Hardcoded Secrets Detected
Impact: API keys, database credentials, and authentication tokens found in source code. Immediate exposure risk if repository is forked or leaked.
Recommended Fix: Move all secrets to environment variables. Use secret management service (AWS Secrets Manager, HashiCorp Vault). Rotate exposed credentials.
HighSecurity
Command Injection via User Input
Impact: 7 instances of subprocess calls with unsanitized user input. Attackers can execute arbitrary system commands.
Recommended Fix: Use subprocess with shell=False and pass arguments as list. Validate and sanitize all user input before system calls.
HighSecurity
Pickle Deserialization
Impact: 5 files use pickle.loads() on untrusted data. Remote code execution vulnerability.
Recommended Fix: Replace pickle with JSON for data serialization. If pickle required, implement strict input validation and signing.
HighPerformance
O(n^4) Nested Loop in Composio Integration
Impact: File: composio_base.py. Quadruple-nested iteration over collections. Performance degrades exponentially with data size.
Recommended Fix: Refactor to use hash maps or indexed lookups. Reduce nesting depth. Consider caching intermediate results.
MediumCorrectness
18 Empty Exception Handlers
Impact: Errors silently swallowed with bare except: pass blocks. Failures go undetected, making debugging impossible.
Recommended Fix: Log exceptions at minimum. Add specific exception handling. Use finally blocks for cleanup, not error suppression.
MediumSecurity
Bind to All Interfaces (0.0.0.0)
Impact: 5 server instances bind to 0.0.0.0, exposing services to external networks without authentication.
Recommended Fix: Bind to 127.0.0.1 for local-only services. Use reverse proxy for external access. Implement authentication layer.
