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-2025-58056 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- io.netty:netty-codec-http (Maven): affected all versions; fixed in 4.1.125.Final\n- io.netty:netty-codec-http (Maven): affected all versions; fixed in 4.1.125.Final\n- io.netty:netty-codec-http (Maven): affected from 4.2.0.Alpha1; fixed in 4.2.5.Final\n- io.netty:netty-codec-http (Maven): affected from 4.2.0.Alpha1; fixed in 4.2.5.Final\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-2025-58056/ (Markdown: https://insights.sbomify.com/CVE-2025-58056/index.md)","id":"CVE-2025-58056","markdown":"https://insights.sbomify.com/CVE-2025-58056/index.md","name":"CVE-2025-58056","record":{"aliases":["CLEANSTART-2026-BY06719","CLEANSTART-2026-DA27362","CLEANSTART-2026-NH27308","CLEANSTART-2026-ZQ44545","CLSA-2026-1776818214","CLSA-2026-1793136168","DEBIAN-CVE-2025-58056","ECHO-564b-afec-8020","GHSA-fghv-69vj-qj49","MINI-2fm8-4c9j-vhh2","MINI-2hjm-6fr8-24j9","MINI-35qf-cxgr-f32p","MINI-3697-cf28-7gpq","MINI-377x-459p-hcvm","MINI-3c2r-564f-p5rf","MINI-447c-w6h6-p76q","MINI-492q-hj39-35jc","MINI-5c36-jwwv-3fpv","MINI-7grg-2977-mvpv","MINI-7h33-gvj6-jqm2","MINI-7w45-3x89-8p43","MINI-85cg-6whw-fh9w","MINI-92jf-wxcc-qhxm","MINI-946p-f46h-jx99","MINI-9p3w-8qhg-7f67","MINI-c7x4-59vq-3jhp","MINI-c9wx-w54h-v36m","MINI-cch6-vr3v-xmpq","MINI-f2fx-5wfj-g7q3","MINI-f4wc-58hg-cx3q","MINI-gmw9-c6p4-2wqj","MINI-h4m3-8c2r-h7r3","MINI-h6x8-cg2c-2563","MINI-j8wv-9m8p-gp38","MINI-jmcg-9rqj-wv3h","MINI-jxhx-qhhj-437c","MINI-m2x2-9f6f-wwh9","MINI-pvjc-4252-gghv","MINI-pww6-jq27-679p","MINI-q3fv-c987-m9j9","MINI-q78f-gwq8-rphc","MINI-qc74-gxj7-2v92","MINI-x48w-7vq6-4gm5","UBUNTU-CVE-2025-58056","USN-7918-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Netty network framework","requires_auth":"none","summary":"Attackers can perform HTTP request smuggling by exploiting incorrect chunk extension parsing in the Netty library, bypassing security controls.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"netty","vendor":"netty"}],"cvss":{"score":2.9,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-444","name":"Inconsistent Interpretation of HTTP Requests"}],"description":"Netty is an asynchronous event-driven network application framework for development of maintainable high performance protocol servers and clients. In versions 4.1.124.Final, and 4.2.0.Alpha3 through 4.2.4.Final, Netty incorrectly accepts standalone newline characters (LF) as a chunk-size line terminator, regardless of a preceding carriage return (CR), instead of requiring CRLF per HTTP/1.1 standards. When combined with reverse proxies that parse LF differently (treating it as part of the chunk extension), attackers can craft requests that the proxy sees as one request but Netty processes as two, enabling request smuggling attacks.
