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-2026-107283 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-2026-107283/ (Markdown: https://insights.sbomify.com/CVE-2026-107283/index.md)","id":"CVE-2026-107283","markdown":"https://insights.sbomify.com/CVE-2026-107283/index.md","name":"CVE-2026-107283","record":{"aliases":["DEBIAN-CVE-2026-107283","ECHO-976a-ccb0-f1c8","GHSA-mfj3-87qq-382v","MINI-2rg5-cpm8-5mcj","MINI-3ww8-2xxm-9gfv","MINI-hmmj-v8mg-7xfq","MINI-jhfm-65fq-h4hm","UBUNTU-CVE-2026-107283"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Java HTTP client library","requires_auth":"none","summary":"AsyncHttpClient uses non-cryptographic randomness for Digest authentication nonces, allowing attackers to potentially bypass authentication protections.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-338","name":"Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)"}],"description":"The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses.

Digest relies on an unpredictable cnonce to resist chosen-plaintext and credential precomputation attacks, so an observer able to infer generator state can reduce the protection of the authentication exchange.
