CVE-2026-41078: CWE-770: Allocation of Resources Without Limits or Throttling in open-telemetry opentelemetry-dotnet
CVE-2026-41078 is a medium severity vulnerability in the OpenTelemetry dotnet telemetry framework, specifically affecting versions 1. 6. 0-rc. 1 and earlier of the OpenTelemetry. Exporter. Jaeger component. The issue involves allocation of resources without limits or throttling, where the internal pooled-list sizing can grow based on a large or attacker-influenced span/tag set and then be reused for subsequent allocations. This behavior can cause sustained memory pressure, increasing memory consumption and potentially leading to denial of service. The component OpenTelemetry. Exporter.
AI Analysis
Technical Summary
OpenTelemetry.Exporter.Jaeger in opentelemetry-dotnet versions up to 1.6.0-rc.1 suffers from a resource allocation vulnerability (CWE-770) where the internal pooled-list size expands in response to large or attacker-controlled telemetry data and retains this enlarged size for future allocations. This can cause sustained memory pressure and increased memory consumption, potentially resulting in denial of service conditions. The affected component was deprecated in 2023, and no remediation or patch is planned.
Potential Impact
The vulnerability can lead to increased memory consumption under conditions of high-cardinality or attacker-influenced telemetry input, which may cause denial of service by exhausting system memory resources. There is no impact on confidentiality or integrity. No known exploits have been reported.
Mitigation Recommendations
There is no official fix or patch available for this vulnerability as the affected component, OpenTelemetry.Exporter.Jaeger, was deprecated in 2023. Users are advised to migrate away from the deprecated exporter to supported telemetry exporters to avoid exposure. Patch status is not yet confirmed for any replacement components; check vendor advisories for current remediation guidance.
