Vulnerability Title
shell-quote `quote()` does not validate object-token shapes, allowing command injection via line terminators in `.op`
Vulnerability Description
shell-quote's `quote()` function did not validate object-token inputs against the operator model used by `parse()`. The `.op` field was backslash-escaped character by character using `/(.)/g`, which in JavaScript does not match line terminators (\n, \r, U+2028, U+2029). A line terminator in `.op` 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 `{ op: '...\n...' }` from external input, and (2) via `parse(cmd, envFn)` when `envFn` returns object tokens whose `.op` is attacker-influenced. Both are documented API surface. Fixed by replacing the per-character escape with strict shape validation: `.op` must match the parser's control-operator allowlist; `{ op: 'glob', pattern }` validates `pattern` and forbids line terminators; `{ comment }` validates `comment` and forbids line terminators; any other object shape throws `TypeError`.

Vulnerability Title
shell-quote 安全漏洞
Vulnerability Description
shell-quote是Jordan Harband个人开发者的一个软件包。用于解析和引用 shell 命令。 shell-quote存在安全漏洞,该漏洞源于quote函数未验证对象令牌输入与parse使用的运算符模型,导致换行符等行终止符未转义,可能被POSIX shell解释为命令分隔符,从而执行后续内容。以下版本受到影响:shell-quote。
