CVE-2026-41078: CWE-770: Allocation of Resources Without Limits or Throttling in open-telemetry opentelemetry-dotnet
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.
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.
