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-2026-107226 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.asynchttpclient:async-http-client (Maven): affected from 2.1.0 up to 2.16.1; no fix listed\n- org.asynchttpclient:async-http-client (Maven): affected from 2.1.0 up to 2.16.1; no fix listed\n- org.asynchttpclient:async-http-client (Maven): affected from 3.0.0; fixed in 3.0.14\n- org.asynchttpclient:async-http-client (Maven): affected from 3.0.0; fixed in 3.0.14\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-2026-107226/ (Markdown: https://insights.sbomify.com/CVE-2026-107226/index.md)","id":"CVE-2026-107226","markdown":"https://insights.sbomify.com/CVE-2026-107226/index.md","name":"CVE-2026-107226","record":{"aliases":["DEBIAN-CVE-2026-107226","GHSA-p2jm-6hj6-9rjg","MINI-47h4-mjh9-39hr","MINI-c842-m4fw-7hxp","UBUNTU-CVE-2026-107226"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Java HTTP client library","requires_auth":"none","summary":"Attackers can manipulate Secure cookies via plaintext HTTP responses, enabling session fixation or CSRF token replacement in Java applications using AsyncHttpClient.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-693","name":"Protection Mechanism Failure"},{"id":"CWE-384","name":"Session Fixation"}],"description":"The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. From 2.1.0 until 3.0.14, the default ThreadSafeCookieStore does not retain whether a Set-Cookie response used a secure transport. It accepts Secure cookies received over plaintext and permits insecure cookies to overlay or delete existing Secure cookies with matching scope. An attacker controlling a plaintext same-site response can consequently plant, replace, or remove cookie state later sent to an HTTPS origin, enabling session fixation, CSRF-token replacement, or loss of security-relevant state.
