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-2026-23941 in the wild and no public exploit code.\n\nAffected product: Erlang OTP. 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-2026-23941/ (Markdown: https://insights.sbomify.com/CVE-2026-23941/index.md)","id":"CVE-2026-23941","markdown":"https://insights.sbomify.com/CVE-2026-23941/index.md","name":"CVE-2026-23941","record":{"aliases":["AZL-79880","DEBIAN-CVE-2026-23941","EEF-CVE-2026-23941","GHSA-w4jc-9wpv-pqh7","UBUNTU-CVE-2026-23941"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Erlang OTP inets","requires_auth":"none","summary":"Attackers can exploit HTTP request smuggling in Erlang OTP inets httpd by sending duplicate Content-Length headers, causing desynchronization with reverse proxies.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"EEF","cpe":[{"product":"erlang\\/inets","vendor":"erlang"},{"product":"erlang\\/otp","vendor":"erlang"}],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:L","version":"4.0"},"cwes":[{"id":"CWE-444","name":"Inconsistent Interpretation of HTTP Requests"}],"description":"Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in Erlang OTP (inets httpd module) allows HTTP Request Smuggling.\n\nThis vulnerability is associated with program files lib/inets/src/http_server/httpd_request.erl and program routines httpd_request:parse_headers/7.\n\nThe server does not reject or normalize duplicate Content-Length headers.
