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-2026-85717 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.asynchttpclient:async-http-client (Maven): affected from 2.14.5; fixed in 2.16.1\n- org.asynchttpclient:async-http-client (Maven): affected from 2.14.5; fixed in 2.16.1\n- org.asynchttpclient:async-http-client (Maven): affected from 3.0.9; fixed in 3.0.12\n- org.asynchttpclient:async-http-client (Maven): affected from 3.0.9; fixed in 3.0.12\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-2026-85717/ (Markdown: https://insights.sbomify.com/CVE-2026-85717/index.md)","id":"CVE-2026-85717","markdown":"https://insights.sbomify.com/CVE-2026-85717/index.md","name":"CVE-2026-85717","record":{"aliases":["ECHO-7764-b5b5-9fbb","GHSA-f8m2-889x-vw4x","MINI-922h-r7vp-fph3","MINI-g37c-928q-vjx3","MINI-qhhj-xprf-wmpc","MINI-xvjh-6ppq-32hg","UBUNTU-CVE-2026-85717"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Java HTTP client library","requires_auth":"none","summary":"AsyncHttpClient leaks client-wide credentials to cross-origin redirect targets when configured with a global realm and redirect following.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-522","name":"Insufficiently Protected Credentials"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. From 2.14.5 to 2.16.0 and from 3.0.9 to 3.0.11, a client configured with a client-wide Realm and redirect following can disclose credentials after a cross-origin redirect because the Interceptors authentication path falls back to the client configuration after redirect handling clears the per-exchange realm. If the attacker-controlled target returns 401, the client can send Basic or Digest credentials or a Negotiate or NTLM token to that origin. Per-request realms are stripped correctly, and this issue is a residual bypass of the earlier cross-origin credential-stripping fixes.
