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-2026-58155 in the wild and no public exploit code.\n\nAffected product: Apache Traffic Server. 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-2026-58155/ (Markdown: https://insights.sbomify.com/CVE-2026-58155/index.md)","id":"CVE-2026-58155","markdown":"https://insights.sbomify.com/CVE-2026-58155/index.md","name":"CVE-2026-58155","record":{"aliases":["DEBIAN-CVE-2026-58155","GHSA-9jfm-2xhc-ghxj","UBUNTU-CVE-2026-58155"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"HTTP proxy server","requires_auth":"none","summary":"Attackers can bypass security policies and smuggle requests by exploiting header name truncation in Apache Traffic Server.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"traffic_server","vendor":"apache"}],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-444","name":"Inconsistent Interpretation of HTTP Requests"}],"description":"Apache Traffic Server truncates over-long header names, allowing header aliasing, request smuggling, and policy bypass.\n\nThis issue affects Apache Traffic Server: from 8.0.0 through 8.1.11, from 9.0.0 through 9.2.14, from 10.0.0 through 10.1.3.\n\nUsers are recommended to upgrade to version 9.2.15 or 10.1.4, which fix the issue.","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":"Apache Traffic Server: Header-name length truncation enables header aliasing and request smuggling","id":"CVE-2026-58155","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apache:traffic_server","products":["apache:traffic_server"],"type":"other","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache Traffic Server: URL and port parsing errors allow access-control bypass","id":"CVE-2026-58156"},"packages":[],"prev":{"headline":"Apache Traffic Server: Memory-safety errors in MIME and header parsing","id":"CVE-2026-58154"},"products":["Apache Traffic Server"],"published":"2026-07-29","related":[{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2014-3525","kev_date_added":null,"published":"2014-08-22"},{"cvss_score":9.8,"headline":"heap-buffer-overflow with stats-over-http plugin","id":"CVE-2021-43082","kev_date_added":null,"published":"2021-11-03"},{"cvss_score":9.8,"headline":"Dynamic stack buffer overflow in cachekey plugin","id":"CVE-2021-35474","kev_date_added":null,"published":"2021-06-30"},{"cvss_score":9.8,"headline":"Other in Apache Traffic Server","id":"CVE-2019-17559","kev_date_added":null,"published":"2020-03-23"},{"cvss_score":9.8,"headline":"Other in Apache Traffic Server","id":"CVE-2019-17565","kev_date_added":null,"published":"2020-03-23"},{"cvss_score":9.8,"headline":"Other in Apache Traffic Server","id":"CVE-2020-1944","kev_date_added":null,"published":"2020-03-23"},{"cvss_score":9.8,"headline":"Security feature bypass in n/a","id":"CVE-2014-3624","kev_date_added":null,"published":"2017-10-30"}],"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":"2026-10-01","vendors":["Apache Software Foundation"]},"summary":"Attackers can bypass security policies and smuggle requests by exploiting header name truncation in Apache Traffic Server.","url":"https://insights.sbomify.com/CVE-2026-58155/"}
