Shell metacharacters are interpreted by the shell, enabling command execution.\n\n\n\n\nImpactThis vulnerability is generally hard to exploit, as it requires --commit-hash to be attacker controlled. The vulnerability primarily affects CI/CD environments where `wrangler pages deploy` is used in automated pipelines and the \n\n--commit-hash parameter is populated from external, potentially untrusted sources.
