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-2025-67721 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- io.airlift:aircompressor (Maven): affected all versions; fixed in 2.0.3\n- io.airlift:aircompressor (Maven): affected all versions; fixed in 2.0.3\n- io.airlift:aircompressor-v3 (Maven): affected all versions; fixed in 3.4\n- io.airlift:aircompressor-v3 (Maven): affected all versions; fixed in 3.4\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-2025-67721/ (Markdown: https://insights.sbomify.com/CVE-2025-67721/index.md)","id":"CVE-2025-67721","markdown":"https://insights.sbomify.com/CVE-2025-67721/index.md","name":"CVE-2025-67721","record":{"aliases":["CLEANSTART-2026-GC04122","CLEANSTART-2026-SD37188","CLSA-2026-1775521829","CLSA-2026-1791306781","CLSA-2026-1792010896","CLSA-2026-1793127929","ECHO-b2ee-bb66-f00f","GHSA-vx9q-rhv9-3jvg","MINI-2v38-gwmp-r23f","MINI-588w-xxxg-q773","MINI-5c4c-6wpw-v8wj","MINI-8232-fx4q-2m4p","MINI-8853-c7h7-v9v5","MINI-fmxg-r2q6-g3wx","MINI-gcrm-rhcv-6gq6","MINI-gvcr-xhm7-h95m","MINI-jgqj-9cj3-9gv7","MINI-jhwm-9fvq-p26x","MINI-v6qx-qhq4-3hxr","MINI-vgjv-229q-fh7v","MINI-vwv7-qh79-hw43","RHLW-2026-a9a544137749200c"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Java compression library","requires_auth":"none","summary":"Remote attackers can leak sensitive data from reused output buffers in Aircompressor's Snappy and LZ4 decompressors via crafted compressed input.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"aircompressor","vendor":"airlift"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-201","name":"Insertion of Sensitive Information Into Sent Data"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Aircompressor is a library with ports of the Snappy, LZO, LZ4, and Zstandard compression algorithms to Java. In versions 3.3 and below, incorrect handling of malformed data in Java-based decompressor implementations for Snappy and LZ4 allow remote attackers to read previous buffer contents via crafted compressed input. With certain crafted compressed inputs, elements from the output buffer can end up in the uncompressed output, potentially leaking sensitive data. This is relevant for applications that reuse the same output buffer to uncompress multiple inputs. This can be the case of a web server that allocates a fix-sized buffer for performance purposes. There is similar vulnerability in GHSA-cmp6-m4wj-q63q.
