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-2026-49361 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.fluss:fluss-common (Maven): affected from 0.8.0-incubating-rc1; fixed in 0.9.1-incubating\n- org.apache.fluss:fluss-common (Maven): affected from 0.8.0-incubating-rc1; fixed in 0.9.1-incubating\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-2026-49361/ (Markdown: https://insights.sbomify.com/CVE-2026-49361/index.md)","id":"CVE-2026-49361","markdown":"https://insights.sbomify.com/CVE-2026-49361/index.md","name":"CVE-2026-49361","record":{"aliases":["GHSA-4c39-fwgj-4vq7"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Fluss server","requires_auth":"none","summary":"Unauthenticated attackers can cause denial of service in Apache Fluss by exhausting JVM heap memory via crafted network frames.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"fluss","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-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Apache Fluss versions prior to 0.9.1 configure the Netty LengthFieldBasedFrameDecoder with Integer.MAX_VALUE as the maximum frame length, allowing unauthenticated remote attackers to exhaust JVM heap memory on TabletServer and CoordinatorServer by sending specially crafted frame headers, resulting in denial of service.\n\nThis issue affects Apache Fluss (incubating): 0.8.0 and 0.9.0.\n\nUsers are recommended to upgrade to version 0.9.1, which fixes the issue.","ecosystems":["Maven"],"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 Fluss Netty Frame Decoder Memory Exhaustion Vulnerability","id":"CVE-2026-49361","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Missing authorization in Apache ActiveMQ Artemis","id":"CVE-2026-49362"},"packages":[{"ecosystem":"Maven","fixed":["0.9.1-incubating"],"introduced":["0.8.0-incubating-rc1"],"last_affected":[],"package":"org.apache.fluss:fluss-common","purl":null,"source":"GHSA-4c39-fwgj-4vq7"},{"ecosystem":"Maven","fixed":["0.9.1-incubating"],"introduced":["0.8.0-incubating-rc1"],"last_affected":[],"package":"org.apache.fluss:fluss-common","purl":"pkg:maven/org.apache.fluss/fluss-common","source":"GHSA-4c39-fwgj-4vq7"}],"prev":{"headline":"Recce server has unauthenticated SQL execution that allows local file read/write through DuckDB","id":"CVE-2026-49360"},"products":["Apache Fluss (incubating)"],"published":"2026-06-01","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2026-06-01","vendors":["Apache Software Foundation"]},"summary":"Unauthenticated attackers can cause denial of service in Apache Fluss by exhausting JVM heap memory via crafted network frames.","url":"https://insights.sbomify.com/CVE-2026-49361/"}
