Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-107281 in the wild and no public exploit code.\n\nAffected product: AsyncHttpClient async-http-client. 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-2026-107281/ (Markdown: https://insights.sbomify.com/CVE-2026-107281/index.md)","id":"CVE-2026-107281","markdown":"https://insights.sbomify.com/CVE-2026-107281/index.md","name":"CVE-2026-107281","record":{"aliases":["DEBIAN-CVE-2026-107281","GHSA-vvp4-63h8-v5pm","UBUNTU-CVE-2026-107281"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Java HTTP client library","requires_auth":"low_privilege","summary":"Attackers can reuse NTLM/Negotiate connections across identities, causing requests to execute as a different user, leading to privilege escalation or data exposure.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-346","name":"Origin Validation Error"}],"description":"The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Prior to 3.0.13 and 2.16.1, the HTTP/1.1 connection-pool key excludes the authenticated principal for connection-oriented NTLM and Negotiate authentication. A pooled socket authenticated for one request can be reused by a request carrying another principal, and the server executes that later request as the first identity. Basic and Digest are not affected because they authenticate each request. This issue is fixed in versions 3.0.13 and 2.16.1.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Auth bypass in async-http-client","id":"CVE-2026-107281","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"AsyncHttpClient: Replay to a different host sends the original host request and credentials to the new host","id":"CVE-2026-107282"},"packages":[],"prev":{"headline":"AsyncHttpClient: Cookie Domain attribute is not checked against the public suffix list, so a cookie can be set for co.uk","id":"CVE-2026-107280"},"products":["async-http-client"],"published":"2026-10-07","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"total"},"state":"PUBLISHED","updated":"2026-10-08","vendors":["AsyncHttpClient"]},"summary":"Attackers can reuse NTLM/Negotiate connections across identities, causing requests to execute as a different user, leading to privilege escalation or data exposure.","url":"https://insights.sbomify.com/CVE-2026-107281/"}
