Error message

security validation failed

What it means

Sentinel ErrSecurityViolation returned by the sandbox manager when the pre-execution security validator rejects a script (manager.go:100) or when the provider reports validation errors in its result (manager.go:137). The script was blocked before/at execution because it violated security policy — this is a deliberate rejection, not a runtime crash.

Solutions

  1. Inspect result.Stderr ('Security validation failed: ...') for the exact rule triggered
  2. Remove the offending construct (network access, file system escapes, privileged commands) from the script
  3. Do not retry unchanged — the block is deterministic by design
  4. Log the attempt for security auditing
Defensive patterns
