  "title": "node-shell-quote: shell-quote\u0027s \u0060quote()\u0060 function did not validate object-token inputs against the operator model used by \u0060parse()\u0060",
  "description": "shell-quote\u0027s \u0060quote()\u0060 function did not validate object-token inputs against the operator model used by \u0060parse()\u0060. The \u0060.op\u0060 field was backslash-escaped character by character using \u0060/(.)/g\u0060, which in JavaScript does not match line terminators (\\n, \\r, U\u002B2028, U\u002B2029). A line terminator in \u0060.op\u0060 therefore passed through unescaped into the output; POSIX shells treat a literal newline as a command separator, so any content after it would execute as a second command. The vulnerable code path is reachable in two ways: (1) direct construction of \u0060{ op: \u0027...\\n...\u0027 }\u0060 from external input, and (2) via \u0060parse(cmd, envFn)\u0060 when \u0060envFn\u0060 returns object tokens whose \u0060.op\u0060 is attacker-influenced. Both are documented API surface. Fixed by replacing the per-character escape with strict shape validation: \u0060.op\u0060 must match the parser\u0027s control-operator allowlist; \u0060{ op: \u0027glob\u0027, pattern }\u0060 validates \u0060pattern\u0060 and forbids line terminators; \u0060{ comment }\u0060 validates \u0060comment\u0060 and forbids line terminators; any other object shape throws \u0060TypeError\u0060.",
