CVE-2026-41483: OpenTelemetry.Resources.Azure has an unbounded HTTP response body read
(updated )
OpenTelemetry.Resources.Azure reads unbounded HTTP response bodies from the Azure VM remote instance metadata service endpoint into memory.
This would allow an attacker-controlled endpoint or one acting as a Man-in-the-Middle (MitM) to cause excessive memory allocation and possible process termination (via Out of Memory (OOM)).
