CVE-2026-41178

OpenTelemetry-Go's baggage parsing no longer caps raw header length

CVSS 5.3 MEDIUMEPSS 0.2%CWE-789

OpenTelemetry-Go is the Go implementation of OpenTelemetry. Versions 1.41.0 and 1.43.0 removed raw-length rejection and it causes `Parse` to process arbitrarily large/invalid baggage headers and log errors, enabling DoS via oversized inputs. Versions 1.42.0 and 1.44.0 fix the issue.
