    CVE-2026-13311 (GCVE-0-2026-13311)

    Vulnerability from nvd – Published: 2026-06-25 04:48 – Updated: 2026-06-25 12:49

    Title
    shell-quote parse() is quadratic in token count, enabling denial of service
    Summary
    shell-quote prior to 1.8.5 finalizes parsed tokens in parse() using Array.prototype.concat as a reduce accumulator, which reallocates and copies the entire growing array on every iteration. As a result parse() runs in O(n^2) time relative to the number of input tokens. An attacker who can supply an attacker-controlled string to any code path that calls parse() (no shell metacharacters are required; plain space-separated words suffice) can block the single-threaded Node.js event loop for an extended period with a small input, resulting in a denial of service. There is no code execution or data disclosure; impact is to availability only. Fixed in 1.8.5.

    CVE-2021-42740 (GCVE-0-2021-42740)

    Vulnerability from nvd – Published: 2021-10-21 14:46 – Updated: 2024-08-04 03:38
    VLAI
    Summary
    The shell-quote package before 1.7.3 for Node.js allows command injection. An attacker can inject unescaped shell metacharacters through a regex designed to support Windows drive letters. If the output of this package is passed to a real shell as a quoted argument to a command with exec(), an attacker can inject arbitrary commands. This is because the Windows drive letter regex character class is {A-z] instead of the correct {A-Za-z]. Several shell metacharacters exist in the space between capital letter Z and lower case letter a, such as the backtick character.
    Severity

    CVE-2026-13311 (GCVE-0-2026-13311)

    Title
    shell-quote parse() is quadratic in token count, enabling denial of service
    Summary
    shell-quote prior to 1.8.5 finalizes parsed tokens in parse() using Array.prototype.concat as a reduce accumulator, which reallocates and copies the entire growing array on every iteration. As a result parse() runs in O(n^2) time relative to the number of input tokens. An attacker who can supply an attacker-controlled string to any code path that calls parse() (no shell metacharacters are required; plain space-separated words suffice) can block the single-threaded Node.js event loop for an extended period with a small input, resulting in a denial of service. There is no code execution or data disclosure; impact is to availability only. Fixed in 1.8.5.

    CVE-2021-42740 (GCVE-0-2021-42740)

    Vulnerability from cvelistv5 – Published: 2021-10-21 14:46 – Updated: 2024-08-04 03:38
    VLAI
    Summary
    The shell-quote package before 1.7.3 for Node.js allows command injection. An attacker can inject unescaped shell metacharacters through a regex designed to support Windows drive letters. If the output of this package is passed to a real shell as a quoted argument to a command with exec(), an attacker can inject arbitrary commands. This is because the Windows drive letter regex character class is {A-z] instead of the correct {A-Za-z]. Several shell metacharacters exist in the space between capital letter Z and lower case letter a, such as the backtick character.
