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-2026-108039 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-2026-108039/ (Markdown: https://insights.sbomify.com/CVE-2026-108039/index.md)","id":"CVE-2026-108039","markdown":"https://insights.sbomify.com/CVE-2026-108039/index.md","name":"CVE-2026-108039","record":{"aliases":["CLEANSTART-2026-IW56621","GHSA-v2mw-x6g2-24jf"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache CXF library","requires_auth":"none","summary":"Attackers can cause denial of service by sending large XML documents to Apache CXF, which previously lacked default parsing limits.","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-776","name":"Improper Restriction of Recursive Entity References in DTDs"}],"description":"By default, StaxUtils placed no limit on the total number of elements or the total number of characters in an XML document. A very large request could therefore use a lot of memory and CPU during parsing, especially where CXF builds a DOM from the input (for example SAAJ or WS-Security), and could cause a denial of service when no request size limit was configured. Both limits now have defaults: the maximum element count is 100 × maxChildElements (5,000,000 by default), and the maximum document size is 256M characters. Applications that process larger documents can raise the limits with the org.apache.cxf.stax.maxElementCount and org.apache.cxf.stax.maxXMLCharacters properties.\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: Prevent unbounded XML document size in StaxUtils by adding default element and character limits","id":"CVE-2026-108039","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":"Pre-authentication OIDC discovery and JWKS fetches run synchronously on the asyncio event loop","id":"CVE-2026-108062"},"packages":[],"prev":{"headline":"eMudhra Compromised Certificate vulnerability impacts HCL Notes Client","id":"CVE-2026-108015"},"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Apache Software Foundation"]},"summary":"Attackers can cause denial of service by sending large XML documents to Apache CXF, which previously lacked default parsing limits.","url":"https://insights.sbomify.com/CVE-2026-108039/"}
