Summary

OpenTelemetry.Exporter.Jaeger in version 1.6.0-rc.1 and earlier may cause sustained memory pressure when the internal pooled-list sizing grows based on a large observed span/tag set and that enlarged size is reused. Under high-cardinality or attacker-influenced telemetry input, this can increase memory consumption and potentially cause denial of service. There is no plan to fix this issue as the exporter was deprecated in 2023.

Risk Assessment

Organizations may experience increased memory usage or denial of service in .NET applications using this exporter. The risk is particularly relevant when processing untrusted telemetry data.

Recommendation

Replace the deprecated OpenTelemetry.Exporter.Jaeger with a supported exporter (e.g., OTLP) and remove it from dependencies. Monitor memory usage in telemetry applications.

Original NVD description (English source)

OpenTelemetry dotnet is a dotnet telemetry framework. In 1.6.0-rc.1 and earlier, OpenTelemetry.Exporter.Jaeger may allow sustained memory pressure when the internal pooled-list sizing grows based on a large observed span/tag set and that enlarged size is reused for subsequent allocations. Under high-cardinality or attacker-influenced telemetry input, this can increase memory consumption and potentially cause denial of service. There is no plan to fix this issue as OpenTelemetry.Exporter.Jaeger was deprecated in 2023.
