An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-6918 exists.\n\nAffected product: Eclipse OpenJ9. 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-2026-6918/ (Markdown: https://insights.sbomify.com/CVE-2026-6918/index.md)","id":"CVE-2026-6918","markdown":"https://insights.sbomify.com/CVE-2026-6918/index.md","name":"CVE-2026-6918","record":{"aliases":["GHSA-q393-vr4c-969r","UBUNTU-CVE-2026-6918"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java JIT Server","requires_auth":"none","summary":"A remote attacker can crash the JITServer by sending a crafted TCP message, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[{"product":"openj9","vendor":"eclipse"}],"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-1286","name":"Improper Validation of Syntactic Correctness of Input"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In Eclipse Open9J versions 0.21 to 0.58, a pre-authentication remote attacker can crash JITServer by sending a 32-byte crafted TCP message.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Denial of service in Eclipse OpenJ9","id":"CVE-2026-6918","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Use after free in Chrome","id":"CVE-2026-6919"},"packages":[],"prev":{"headline":"Cross-site scripting in Jeg Kit for Elementor – Powerful Addons for Elementor, Widgets \u0026 Templates for WordPress","id":"CVE-2026-6916"},"products":["Eclipse OpenJ9"],"published":"2026-05-05","related":[{"cvss_score":9.8,"headline":"Security feature bypass in Eclipse OMR","id":"CVE-2021-41035","kev_date_added":null,"published":"2021-10-25"},{"cvss_score":9.8,"headline":"Memory corruption in Eclipse OpenJ9","id":"CVE-2020-27221","kev_date_added":null,"published":"2021-01-21"},{"cvss_score":9.8,"headline":"Memory corruption in Eclipse OpenJ9","id":"CVE-2019-11772","kev_date_added":null,"published":"2019-07-17"},{"cvss_score":9.8,"headline":"Memory corruption in Eclipse OpenJ9","id":"CVE-2018-12547","kev_date_added":null,"published":"2019-02-11"},{"cvss_score":9.8,"headline":"Null dereference in Eclipse OpenJ9","id":"CVE-2018-12549","kev_date_added":null,"published":"2019-02-11"},{"cvss_score":9.8,"headline":"Memory corruption in Eclipse OpenJ9","id":"CVE-2018-12548","kev_date_added":null,"published":"2019-01-31"},{"cvss_score":9.1,"headline":"Missing authorization in Eclipse OpenJ9","id":"CVE-2019-17631","kev_date_added":null,"published":"2019-10-17"}],"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-15","vendors":["Eclipse Foundation"]},"summary":"A remote attacker can crash the JITServer by sending a crafted TCP message, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2026-6918/"}
