moment is a JavaScript date library for parsing, validating, manipulating, and formatting dates. In versions 2.29.2 through 2.30.1, a specially crafted non-string object passed to moment.locale() can bypass the locale-name path-traversal guard. The guard assumes the input is a string, so an object whose match() method satisfies the check while its toString() returns a traversal path reaches an internal require() call with attacker-controlled path segments. This is an incomplete fix for CVE-2022-24785 and primarily affects npm (server-side) users that pass user-provided input directly to moment.locale(). The issue is fixed in moment 2.31.0, and users should upgrade to 2.31.0 or later. As a workaround, validate that any user-supplied input is a string before passing it to moment.locale().
