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-2026-33930 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-2026-33930/ (Markdown: https://insights.sbomify.com/CVE-2026-33930/index.md)","id":"CVE-2026-33930","markdown":"https://insights.sbomify.com/CVE-2026-33930/index.md","name":"CVE-2026-33930","record":{"aliases":["DEBIAN-CVE-2026-33930","GHSA-4p58-9v5g-254v","UBUNTU-CVE-2026-33930"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Traffic Server","requires_auth":"none","summary":"An attacker can trigger a stack buffer overflow via a long Host header when redirect following is enabled, potentially leading to code execution or service disruption.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"traffic_server","vendor":"apache"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Apache Traffic Server copies the client Host header into a fixed-size stack buffer without a bound during redirect handling, so an over-long Host header overflows the stack when redirect following is enabled.\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: Buffer overflow via Host field that has a long string value","id":"CVE-2026-33930","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apache:traffic_server","products":["apache:traffic_server"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"OpenEMR has IDOR in Portal Payment Page that Allows Cross-Patient Record Access","id":"CVE-2026-33931"},"packages":[],"prev":{"headline":"Apache PDFBox Examples: Path Traversal in PDFBox ExtractEmbeddedFiles Example Code","id":"CVE-2026-33929"},"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-01","vendors":["Apache Software Foundation"]},"summary":"An attacker can trigger a stack buffer overflow via a long Host header when redirect following is enabled, potentially leading to code execution or service disruption.","url":"https://insights.sbomify.com/CVE-2026-33930/"}
