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-2026-67465 in the wild and no public exploit code.\n\nAffected product: Apache Qpid Proton Dotnet. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-67465/ (Markdown: https://insights.sbomify.com/CVE-2026-67465/index.md)","id":"CVE-2026-67465","markdown":"https://insights.sbomify.com/CVE-2026-67465/index.md","name":"CVE-2026-67465","record":{"aliases":["GHSA-pr7j-v7jr-j955"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Qpid Proton Dotnet library","requires_auth":"none","summary":"A pre-authentication attacker can cause resource exhaustion and denial of service via unbounded symbol value caching in the Qpid Proton Dotnet library.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"qpid_proton-dotnet","vendor":"apache"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","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":"A pre-authentication attacker could leverage unbounded symbol value caching to cause resource exhaustion leading to denial of service.\n\nThis issue affects Apache Qpid Proton-Dotnet: through 1.0.0.\n\nUsers are recommended to upgrade to version 1.1.0, which fixes the issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Apache Qpid Proton Dotnet: Unbounded symbol value caching can lead to pre-authentication resource exhaustion","id":"CVE-2026-67465","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"OpenProject: Improper Access Control through /api/v3/work_packages/\u003cX.id\u003e via PATCH parameter \"fileLinks\"","id":"CVE-2026-67527"},"packages":[],"prev":{"headline":"Memory corruption in Warp","id":"CVE-2026-67456"},"products":["Apache Qpid Proton Dotnet"],"published":"2026-08-05","related":[{"cvss_score":7.5,"headline":"Apache Qpid Proton Dotnet: Type size/count handling can lead to excessive allocation pre-authentication","id":"CVE-2026-67551","kev_date_added":null,"published":"2026-08-05"},{"cvss_score":7.5,"headline":"Apache Qpid Proton Dotnet: Unbounded type nesting can lead to pre-authentication stackoverflow","id":"CVE-2026-67552","kev_date_added":null,"published":"2026-08-05"},{"cvss_score":6.5,"headline":"Apache Qpid Proton Dotnet: Incoming session flow control window can be exceeded","id":"CVE-2026-67553","kev_date_added":null,"published":"2026-08-05"},{"cvss_score":6.5,"headline":"Apache Qpid Proton Dotnet: Unbounded disposition range handling can lead to denial of service","id":"CVE-2026-67554","kev_date_added":null,"published":"2026-08-05"},{"cvss_score":6.5,"headline":"Apache Qpid Proton Dotnet: Unable to govern the maximum number of transfer frames per incoming delivery","id":"CVE-2026-67555","kev_date_added":null,"published":"2026-08-05"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-06","vendors":["Apache Software Foundation"]},"summary":"A pre-authentication attacker can cause resource exhaustion and denial of service via unbounded symbol value caching in the Qpid Proton Dotnet library.","url":"https://insights.sbomify.com/CVE-2026-67465/"}
