idnafrom 3.7 to 3.15 inaws/logs_monitoring/requirements.txt.Motivation
Addresses CVE-2026-45409, a DoS vulnerability in the
idnalibrary where craftedinputs to
idna.encode()consume excessive resources before length validation.The fix in 3.14/3.15 rejects oversized inputs early.
idnais a transitivedependency pulled in by
requests.Testing Guidelines
No behavior change — this is a transitive dependency not called directly by this
codebase.
requests==2.33.0acceptsidna<4,>=2.5, so 3.15 is fully compatible.Additional Notes
idnais not used directly in this repo; it is resolved transitively viarequests.The vulnerable code path (passing untrusted hostnames to
idna.encode()) is notreachable in this Lambda — all outbound URLs are operator-configured env vars with
hardcoded Datadog defaults.
