A GitHub-reviewed security advisory, not necessarily under active exploitation the way our CISA KEV advisories are, but a real, disclosed vulnerability in an open-source dependency.
Affected packages
Vulnerable: >= 2.29.2, < 2.31.0
Patched in 2.31.0
Details
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.
This issue is patched in moment 2.31.0.
Validate that any user-supplied input is a string before passing it to moment.locale().
EPSS, exploit probability
Low0.52%
estimated chance of real-world exploitation in the next 30 days, higher than 44.7% of every CVE FIRST.org scores
Refreshed 11/14/2026, via FIRST.org's EPSS model, not CVSS, this measures likelihood of exploitation, not how severe it would be.
