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-2026-67590 in the wild and no public exploit code.\n\nAffected product: Apache Qpid ProtonJ2. 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-2026-67590/ (Markdown: https://insights.sbomify.com/CVE-2026-67590/index.md)","id":"CVE-2026-67590","markdown":"https://insights.sbomify.com/CVE-2026-67590/index.md","name":"CVE-2026-67590","record":{"aliases":["GHSA-hgf5-hpf4-qmrr","UBUNTU-CVE-2026-67590"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java AMQP library","requires_auth":"none","summary":"A pre-authentication attacker can cause a denial of service via unbounded type nesting in Apache Qpid ProtonJ2.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"qpid_protonj2","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-674","name":"Uncontrolled Recursion"}],"description":"A pre-authentication attacker could leverage type nesting to cause a StackOverflowError potentially leading to denial of service.\n\nThis issue affects Apache Qpid ProtonJ2: through 1.1.0.\n\nUsers are recommended to upgrade to version 1.2.0, 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 ProtonJ2: Unbounded type nesting can lead to pre-authentication stackoverflow","id":"CVE-2026-67590","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":"Apache Qpid ProtonJ2: Incoming session flow control window can be exceeded","id":"CVE-2026-67591"},"packages":[],"prev":{"headline":"Apache Qpid ProtonJ2: Type size/count handling can lead to excessive allocation pre-authentication","id":"CVE-2026-67589"},"products":["Apache Qpid ProtonJ2"],"published":"2026-08-05","related":[{"cvss_score":7.5,"headline":"Apache Qpid ProtonJ2: Unbounded symbol value caching can lead to pre-authentication resource exhaustion","id":"CVE-2026-67588","kev_date_added":null,"published":"2026-08-05"},{"cvss_score":7.5,"headline":"Apache Qpid ProtonJ2: Type size/count handling can lead to excessive allocation pre-authentication","id":"CVE-2026-67589","kev_date_added":null,"published":"2026-08-05"},{"cvss_score":7.5,"headline":"Apache Qpid ProtonJ2: Unable to govern the maximum number of transfer frames per incoming delivery","id":"CVE-2026-67592","kev_date_added":null,"published":"2026-08-05"},{"cvss_score":6.5,"headline":"Apache Qpid ProtonJ2: Incoming session flow control window can be exceeded","id":"CVE-2026-67591","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 a denial of service via unbounded type nesting in Apache Qpid ProtonJ2.","url":"https://insights.sbomify.com/CVE-2026-67590/"}
