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-2026-107285 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.asynchttpclient:async-http-client (Maven): affected from 2.0.0; fixed in 2.16.1\n- org.asynchttpclient:async-http-client (Maven): affected from 2.0.0; fixed in 2.16.1\n- org.asynchttpclient:async-http-client (Maven): affected from 3.0.0; fixed in 3.0.12\n- org.asynchttpclient:async-http-client (Maven): affected from 3.0.0; 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-2026-107285/ (Markdown: https://insights.sbomify.com/CVE-2026-107285/index.md)","id":"CVE-2026-107285","markdown":"https://insights.sbomify.com/CVE-2026-107285/index.md","name":"CVE-2026-107285","record":{"aliases":["DEBIAN-CVE-2026-107285","ECHO-d74c-6231-875e","GHSA-3wp9-xfwm-rjjf","MINI-4rvw-jj9j-cccm","MINI-phmx-4gpx-c53x","MINI-q6ff-r5qp-pr57","MINI-q7qc-c49h-8fhp","UBUNTU-CVE-2026-107285"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Java HTTP client library","requires_auth":"none","summary":"AsyncHttpClient leaks proxy credentials to origin servers during WebSocket connections, allowing attackers to recover or replay authentication data.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-522","name":"Insufficiently Protected Credentials"},{"id":"CWE-319","name":"Cleartext Transmission of Sensitive Information"}],"description":"The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Prior to 3.0.12 and 2.16.1, a proxied ws request is carried through CONNECT, but NettyRequestFactory.newNettyRequest and requestUri decide whether to attach proxy authentication and an absolute-form target only from whether the URI is secure. Because ws is not marked secure, the tunneled WebSocket upgrade sent to the origin includes the proxy's Proxy-Authorization value. Basic credentials are directly recoverable and Digest responses can be replayed or cracked offline.
