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-2026-19204 in the wild and no public exploit code.\n\nAffected product: Eclipse Jetty. 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-2026-19204/ (Markdown: https://insights.sbomify.com/CVE-2026-19204/index.md)","id":"CVE-2026-19204","markdown":"https://insights.sbomify.com/CVE-2026-19204/index.md","name":"CVE-2026-19204","record":{"aliases":["CLEANSTART-2026-SV46004","CLEANSTART-2026-TT31497","CLEANSTART-2026-VO81158","DEBIAN-CVE-2026-19204","GHSA-85fq-fc5f-7j7g","GHSA-w753-5ffq-99wr","UBUNTU-CVE-2026-19204"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Java web server","requires_auth":"none","summary":"Attackers can exhaust JVM heap memory via crafted WebSocket frames when auto-fragmentation is enabled, causing denial of service in Jetty servers.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-789","name":"Memory Allocation with Excessive Size Value"},{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"A client may send a WebSocket frame with an unknown opcode and a very large declared payload length, causing Jetty to attempt a large memory allocation and potentially exhaust the JVM heap.\n\nThis occurs when auto-fragmentation is enabled, as unknown opcodes bypass the normal maximum frame size handling and payload allocation occurs before the opcode is validated.","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":"Denial of service in Eclipse Jetty","id":"CVE-2026-19204","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":"User Enumeration in GastroMenum's GastroMenum Web Panel","id":"CVE-2026-19205"},"packages":[],"prev":{"headline":"A client may issue specially crafted HTTP/1.1 chunked requests to a Jetty server that cause Jetty and an intermediary proxy to interpret dif","id":"CVE-2026-19203"},"products":["Eclipse Jetty"],"published":"2026-09-07","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-09-08","vendors":["Eclipse Foundation"]},"summary":"Attackers can exhaust JVM heap memory via crafted WebSocket frames when auto-fragmentation is enabled, causing denial of service in Jetty servers.","url":"https://insights.sbomify.com/CVE-2026-19204/"}
