    Regular Expression Denial of Service (ReDoS)

    semver is a semantic version parser used by npm.

    Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) via the function new Range, when untrusted user data is provided as a range.

    Regular Expression Denial of Service (ReDoS)

    semver is a semantic version parser used by npm.

    Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS). The semver module uses regular expressions when parsing a version string. For a carefully crafted input, the time it takes to process these regular expressions is not linear to the length of the input. Since the semver module did not enforce a limit on the version string length, an attacker could provide a long string that would take up a large amount of resources, potentially taking a server down. This issue therefore enables a potential Denial of Service attack.

    How to fix Regular Expression Denial of Service (ReDoS)?

    Upgrade semver to version 4.3.2 or higher.

    <4.3.2
