## Engram Starter Utility Exposes Code Injection Risk via Dynamic syscall.Exec Arguments
A high-severity security flaw has been identified in the Engram project's starter utility, where the use of a dynamic argument vector (`argv`) with the `syscall.Exec` function creates a direct path for code injection. The vulnerability, flagged as 'Blocking / High' by automated scanning, resides in `cmd/starter/main.go` at line 100. This critical point executes the `/engram` binary, but the arguments passed to it are not statically defined, opening a door for malicious actors to potentially hijack the execution flow and run arbitrary code.

The risk is concentrated in how the `argv` slice is constructed before the `syscall.Exec` call. If any element within this slice is derived from unvalidated external input—such as user-provided data, environment variables, or configuration files—it becomes a viable injection vector. An attacker could manipulate these inputs to append malicious command-line arguments or alter the execution path, effectively bypassing intended security boundaries. The finding was automatically detected by Semgrep using the `go.lang.security.audit.dangerous-syscall-exec` rule, underscoring a common but dangerous pattern in Go system-level programming.

Immediate action is required to audit all call sites where the `argv` for this syscall is built. The remediation path is strict: every element must be either hardcoded or rigorously validated against a predefined allowlist before reaching the execution function. This places significant scrutiny on the project's input validation and configuration parsing routines, as failure to lock down these data flows could compromise the entire utility's security posture. The finding serves as a critical warning for developers handling system calls with dynamic parameters, a practice that demands extreme caution to prevent exploitation.
