The vulnerability (signed 32-bit integer wraparound causing infinite loops, process crashes, or data corruption when List operations receive indices >= 2^30) has been fixed by upstream commit 0fe3f772e3 authored by Zo\u00e9 de Moffarts (Workday) on 2026-07-27, merged into the 3.x branch and released in v3.8.4. The fix adds validation (`validateListBoundsRequest`) that throws RangeError before the lossy `| 0` coercion, and replaces wrapping `1 << exp` with `levelCapacity()` helper that uses `Math.pow(2, exp)` for exp >= 31. This is an upstream/vendor fix with no TuxCare attribution (author domain @workday.com, merge committer @gmail.com, no corporate GitLab profiles, no Jira references).",
