OpenTelemetry, also known as OTel for short, is a vendor-neutral open-source Observability framework for instrumenting, generating, collecting, and exporting telemetry data such as traces, metrics, logs. Autoinstrumentation out of the box adds the label httpmethod that has unbound cardinality. It...

CVE-2023-43810

CVE-2023-43810 concerns OpenTelemetry instrumentation. Autoinstrumentation may expose an unbounded http_method label, enabling memory exhaustion under large numbers of crafted requests. Affected if the application is instrumented for HTTP handlers and does not filter non-standard methods at CDN/L...

GHSA-5RV5-6H4R-H22V opentelemetry-instrumentation Denial of Service vulnerability due to unbound cardinality metrics

Summary Autoinstrumentation out of the box adds the label httpmethod that has unbound cardinality. It leads to the server's potential memory exhaustion when many malicious requests are sent. Details HTTP method for requests can be easily set by an attacker to be random and long. PoC Send many...
