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-2026-107282 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 3.0.13\n- org.asynchttpclient:async-http-client (Maven): affected from 3.0.0; fixed in 3.0.13\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-2026-107282/ (Markdown: https://insights.sbomify.com/CVE-2026-107282/index.md)","id":"CVE-2026-107282","markdown":"https://insights.sbomify.com/CVE-2026-107282/index.md","name":"CVE-2026-107282","record":{"aliases":["DEBIAN-CVE-2026-107282","ECHO-6e4c-a2b2-3885","GHSA-jmqq-x5g9-9p2w","MINI-7cgc-w56m-2ww4","MINI-rg5m-vgf5-8gg5","MINI-wmh2-w729-gc6h","MINI-xj9r-m682-mqpr","ROOT-APP-MAVEN-CVE-2026-107282","UBUNTU-CVE-2026-107282"],"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":"Attackers can intercept sensitive credentials and request data when cross-host replays incorrectly target the original host's context, affecting Java applications using AsyncHttpClient.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-522","name":"Insufficiently Protected Credentials"},{"id":"CWE-441","name":"Unintended Proxy or Intermediary"},{"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 3.0.13  and 2.16.1, cross-host request replay updates the current request but leaves the target request and related proxy context pointing at the original origin. Connection-pool selection, CONNECT handling, realm selection, and TLS setup can consequently send the original host's path, Host header, Authorization credentials, or plaintext request to the replay destination. Documented ResponseFilter failover and retry paths can trigger the replay.
