YAML Security Issue

The scanner detected YAML content with patterns that could lead to security vulnerabilities. YAML is a powerful configuration format that, when parsed unsafely, can execute code or cause denial of service.

YAML deserialization vulnerabilities are a well-known attack vector. Dangerous patterns include:

• Object instantiation — Python's !!python/object or Ruby's !ruby/object can execute arbitrary code
• Alias bombs — Recursive anchor references can cause infinite loops or memory exhaustion
• Shell execution — Some YAML parsers allow embedded shell commands

• Configuration files from Python/Ruby applications
• Documentation about YAML security (describing, not exploiting)
• CI/CD pipeline definitions (GitHub Actions, GitLab CI)
• Kubernetes or Docker Compose files
• Legitimate use of anchors and aliases for DRY configuration

Review the YAML content:

• If it's configuration from a trusted source, it's likely safe
• Check for !!python or !ruby tags — these are almost never needed in agent memory
• Excessive anchor/alias usage (&anchor, *alias) may indicate an attack
• Environment variable references ($ENV, ${VAR}) should be reviewed for sensitive data
