An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-27513 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- OpenTelemetry.Api (NuGet): affected all versions; no fix listed\n- OpenTelemetry.Api (NuGet): affected all versions; no fix listed\n- OpenTelemetry.Api (NuGet): affected from 1.11.0; fixed in 1.11.2\n- OpenTelemetry.Api (NuGet): affected from 1.11.0; fixed in 1.11.2\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-27513/ (Markdown: https://insights.sbomify.com/CVE-2025-27513/index.md)","id":"CVE-2025-27513","markdown":"https://insights.sbomify.com/CVE-2025-27513/index.md","name":"CVE-2025-27513","record":{"aliases":["GHSA-8785-wc3w-h8q6"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenTelemetry .NET library","requires_auth":"none","summary":"Attackers can cause denial of service via high CPU usage by sending crafted tracestate headers to applications using the OpenTelemetry .NET API.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"OpenTelemetry dotnet is a dotnet telemetry framework. A vulnerability in OpenTelemetry.Api package 1.10.0 to 1.11.1 could cause a Denial of Service (DoS) when a tracestate and traceparent header is received. Even if an application does not explicitly use trace context propagation, receiving these headers can still trigger high CPU usage. This issue impacts any application accessible over the web or backend services that process HTTP requests containing a tracestate header. Application may experience excessive resource consumption, leading to increased latency, degraded performance, or downtime.
