MODERATE

A Regular Expression Denial of Service vulnerability was discovered in esm before 3.1.0. The issue is that esm's find-indexes is using the unescaped identifiers in a regex, which, in this case, causes an infinite loop.

Checked 2026-10-03 at 18:56 UTC. The most recent advisory here was published 2019-06-20. Updated continuously from NVD, GHSA, OSV and CNA feeds.
