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-2026-86463 in the wild and no public exploit code.\n\nAffected product: Apache Cxf. 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-2026-86463/ (Markdown: https://insights.sbomify.com/CVE-2026-86463/index.md)","id":"CVE-2026-86463","markdown":"https://insights.sbomify.com/CVE-2026-86463/index.md","name":"CVE-2026-86463","record":{"aliases":["CLEANSTART-2026-XT41659","GHSA-ppm6-prq5-wv37"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java web services library","requires_auth":"none","summary":"An attacker can cause excessive CPU consumption in Apache CXF by sending crafted FIQL queries, leading to service disruption.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"cxf","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-400","name":"Uncontrolled Resource Consumption"}],"description":"Apache CXF's FIQL query parser has a vulnerability in how it searches for operators in query expressions. The search pattern can get stuck trying many combinations when it encounters a long string without an operator, causing the parser to consume excessive CPU time. An attacker can send a crafted query to make the server use up CPU resources, potentially slowing down or stopping other requests. The fix was to limit FIQL expressions to 4 KiB by default, preventing attackers from sending extremely long inputs while still allowing normal queries.\n\nUsers are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this 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":true,"headline":"Apache CXF: FIQL Query Parser Denial of Service","id":"CVE-2026-86463","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apache:cxf","products":["apache:cxf"],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Hardcoded credentials in Eclipse aeriOS","id":"CVE-2026-86464"},"packages":[],"prev":{"headline":"Apache Airflow FAB provider: FAB Admin password PATCH does not invalidate database-backed sessions","id":"CVE-2026-86462"},"products":["Apache CXF"],"published":"2026-10-09","related":[{"cvss_score":10,"headline":"XML Signature/Encryption Not Validated in Apache CXF","id":"CVE-2012-2379","kev_date_added":null,"published":"2013-01-03"},{"cvss_score":9.8,"headline":"Apache CXF: Unsafe deserialization of inbound JMS ObjectMessage","id":"CVE-2026-66909","kev_date_added":null,"published":"2026-08-06"},{"cvss_score":9.8,"headline":"Apache CXF: DefaultEncryptingCodeDataProvider allows unlimited authorization code replay","id":"CVE-2026-68079","kev_date_added":null,"published":"2026-08-06"},{"cvss_score":9.8,"headline":"Apache CXF: OAuth2: Inverted IP Binding Check Defeats Security Control","id":"CVE-2026-50628","kev_date_added":null,"published":"2026-06-12"},{"cvss_score":9.8,"headline":"Apache CXF: Untrusted JMS configuration can lead to RCE","id":"CVE-2025-48913","kev_date_added":null,"published":"2025-08-08"},{"cvss_score":9.8,"headline":"Apache CXF SSRF Vulnerability","id":"CVE-2022-46364","kev_date_added":null,"published":"2022-12-13"},{"cvss_score":9.8,"headline":"Potential session hijack in Apache CXF","id":"CVE-2019-12419","kev_date_added":null,"published":"2019-11-06"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Apache Software Foundation"]},"summary":"An attacker can cause excessive CPU consumption in Apache CXF by sending crafted FIQL queries, leading to service disruption.","url":"https://insights.sbomify.com/CVE-2026-86463/"}
