GHSA-4p3w-j4w9-5jqw moment vulnerable to Path Traversal via crafted non-string locale name

• npm moment: >= 2.29.2, < 2.31.0 → fixed in 2.31.0

Impact moment before 2.31.0 is vulnerable to path traversal in `moment.locale()`. When an application passes a non-string, attacker-influenced value to `moment.locale()`, a specially crafted object can bypass the locale name validation and cause moment to load a file from an attacker-controlled path. This is a further bypass of the validation added in 2.29.2 for CVE-2022-24785. This affects server-side (npm) users only. Plain string input is not affected: the existing validation correctly rejects strings that contain path separators. Patches This issue is patched in moment 2.31.0. Workarounds Validate that any user-supplied input is a string before passing it to `moment.locale()`.
