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-2026-47874/ (Markdown: https://insights.sbomify.com/CVE-2026-47874/index.md)","id":"CVE-2026-47874","markdown":"https://insights.sbomify.com/CVE-2026-47874/index.md","name":"CVE-2026-47874","record":{"aliases":["CLEANSTART-2026-DB50494","CLEANSTART-2026-KN48533","CLEANSTART-2026-NO71028","CLEANSTART-2026-YL03926","CLEANSTART-2026-YV14611","GHSA-fg4q-58fc-39w8"],"analysis":null,"analysis_generated_by":null,"assigner":"vmware","cpe":[{"product":"reactor_netty","vendor":"pivotal"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"The vulnerability occurs when a client sends HTTP/1.1 pipelined requests over a single connection, causing the Reactor Netty HTTP server to consume an excessive amount of memory.\nReactor Netty 1.3.0 - 1.3.6\nReactor Netty 1.1.0 - 1.2.18\nReactor Netty 1.0.52 and earlier","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":"Reactor Netty HTTP Server Denial of Service With Pipelined Requests","id":"CVE-2026-47874","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"JobParameterDeserializer bypasses the trusted-type allowlist","id":"CVE-2026-47875"},"packages":[],"prev":{"headline":"Spring Tools Docker integration publishes unauthenticated debug (JDWP) and JMX ports on all network interfaces","id":"CVE-2026-47873"},"products":["Reactor Netty"],"published":"2026-08-26","related":[],"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":"2026-08-27","vendors":["Spring"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-47874/"}
