Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-14763 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- software.amazon.encryption.s3:amazon-s3-encryption-client-java (Maven): affected all versions; fixed in 4.0.0\n- software.amazon.encryption.s3:amazon-s3-encryption-client-java (Maven): affected all versions; fixed in 4.0.0\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-2025-14763/ (Markdown: https://insights.sbomify.com/CVE-2025-14763/index.md)","id":"CVE-2025-14763","markdown":"https://insights.sbomify.com/CVE-2025-14763/index.md","name":"CVE-2025-14763","record":{"aliases":["CLEANSTART-2026-EK12616","CLEANSTART-2026-NG64025","GHSA-x44p-gvrj-pj2r","ROOT-APP-MAVEN-CVE-2025-14763"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Java S3 encryption library","requires_auth":"low_privilege","summary":"A user with write access can manipulate encrypted data keys in instruction files, potentially causing decryption to different plaintexts.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMZN","cpe":[],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"Missing cryptographic key commitment in the Amazon S3 Encryption Client for Java may allow a user with write access to the S3 bucket to introduce a new EDK that decrypts to different plaintext when the encrypted data key is stored in an \"instruction file\" instead of S3's metadata record.\n\nTo mitigate this issue, upgrade Amazon S3 Encryption Client for Java to version 4.0.0 or later.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Amazon S3 Encryption Client for Java has a Key Commitment Issue","id":"CVE-2025-14763","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"weak_cryptography","year":"2025"},"n_packages":2,"n_references":3,"next":{"headline":"Amazon S3 Encryption Client has a Key Commitment Issue","id":"CVE-2025-14764"},"packages":[{"ecosystem":"Maven","fixed":["4.0.0"],"introduced":["0"],"last_affected":[],"package":"software.amazon.encryption.s3:amazon-s3-encryption-client-java","purl":null,"source":"GHSA-x44p-gvrj-pj2r"},{"ecosystem":"Maven","fixed":["4.0.0"],"introduced":["0"],"last_affected":[],"package":"software.amazon.encryption.s3:amazon-s3-encryption-client-java","purl":"pkg:maven/software.amazon.encryption.s3/amazon-s3-encryption-client-java","source":"GHSA-x44p-gvrj-pj2r"}],"prev":{"headline":"AWS SDK for Ruby's S3 Encryption Client has a Key Commitment Issue","id":"CVE-2025-14762"},"products":["S3 Encryption Client for Java"],"published":"2025-12-17","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-12-17","vendors":["AWS"]},"summary":"A user with write access can manipulate encrypted data keys in instruction files, potentially causing decryption to different plaintexts.","url":"https://insights.sbomify.com/CVE-2025-14763/"}
