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-2026-41483 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- OpenTelemetry.Resources.Azure (NuGet): affected all versions; fixed in 1.15.1-beta.1\n- OpenTelemetry.Resources.Azure (NuGet): affected all versions; fixed in 1.15.1-beta.1\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-2026-41483/ (Markdown: https://insights.sbomify.com/CVE-2026-41483/index.md)","id":"CVE-2026-41483","markdown":"https://insights.sbomify.com/CVE-2026-41483/index.md","name":"CVE-2026-41483","record":{"aliases":["GHSA-vc24-j8c5-2vw4"],"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":"An attacker can cause a denial of service by forcing the Azure VM resource detector to consume excessive memory via large HTTP responses.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"opentelemetry.resources.azure","vendor":"opentelemetry"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/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.Resources.Azure is the .NET resource detector for Azure environments. In versions 1.15.0-beta.1 and earlier, the AzureVmMetaDataRequestor class makes HTTP requests to the Azure VM instance metadata service and reads the response body into memory without any size limit. An attacker who controls the configured endpoint, or who can intercept traffic to it via a man-in-the-middle attack, can return an arbitrarily large response body. This causes unbounded heap allocation in the consuming process, leading to high transient memory pressure, garbage-collection stalls, or an OutOfMemoryException that terminates the process. As a workaround, disable the Azure VM resource detector or use network-level controls such as firewall rules, mTLS, or a service mesh to prevent man-in-the-middle attacks on the Azure VM instance metadata endpoint. This issue is fixed in version 1.15.1-beta.1, which streams responses rather than buffering them entirely in memory and ignores responses larger than 4 MiB.","ecosystems":["NuGet"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Unbounded HTTP response body read in OpenTelemetry.Resources.Azure","id":"CVE-2026-41483","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"OpenTelemetry.Exporter.OneCollector vulnerable to denial of service via unbounded HTTP error response body","id":"CVE-2026-41484"},"packages":[{"ecosystem":"NuGet","fixed":["1.15.1-beta.1"],"introduced":["0"],"last_affected":[],"package":"OpenTelemetry.Resources.Azure","purl":null,"source":"GHSA-vc24-j8c5-2vw4"},{"ecosystem":"NuGet","fixed":["1.15.1-beta.1"],"introduced":["0"],"last_affected":[],"package":"OpenTelemetry.Resources.Azure","purl":"pkg:nuget/OpenTelemetry.Resources.Azure","source":"GHSA-vc24-j8c5-2vw4"}],"prev":{"headline":"Frappe: Possible Path Traversal and Local File Inclusion via Chrome PDF Generator","id":"CVE-2026-41482"},"products":["opentelemetry-dotnet-contrib"],"published":"2026-05-06","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-07","vendors":["open-telemetry"]},"summary":"An attacker can cause a denial of service by forcing the Azure VM resource detector to consume excessive memory via large HTTP responses.","url":"https://insights.sbomify.com/CVE-2026-41483/"}
