Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-19642 in the wild and no public exploit code.\n\nAffected product: aws-sdk-cpp. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-19642/ (Markdown: https://insights.sbomify.com/CVE-2026-19642/index.md)","id":"CVE-2026-19642","markdown":"https://insights.sbomify.com/CVE-2026-19642/index.md","name":"CVE-2026-19642","record":{"aliases":["GHSA-wxx3-prfc-69xx"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"AWS C++ SDK","requires_auth":"low_privilege","summary":"A remote authenticated user can trigger heap memory corruption or crashes in applications using the AWS C++ SDK via crafted Base64 input.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMZN","cpe":[{"product":"aws_software_development_kit","vendor":"amazon"}],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"An out-of-bounds write issue in the Base64 decoder in Amazon aws-sdk-cpp before 1.11.862 might allow a remote authenticated user to cause a crash or heap memory corruption in an application that processes crafted Base64-encoded input.\n\nTo remediate this issue, users should upgrade to version 1.11.862.","ecosystems":[],"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":"Out-of-bounds write in the Base64 decoder in Amazon aws-sdk-cpp","id":"CVE-2026-19642","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Out-of-bounds read in the Base64 decoder in Amazon aws-sdk-cpp on signed-char platforms","id":"CVE-2026-19643"},"packages":[],"prev":{"headline":"Denial of service in EOS","id":"CVE-2026-19641"},"products":["aws-sdk-cpp"],"published":"2026-08-12","related":[{"cvss_score":7.2,"headline":"Information disclosure in n/a","id":"CVE-2018-19981","kev_date_added":null,"published":"2019-04-04"},{"cvss_score":6,"headline":"Out-of-bounds read in the Base64 decoder in Amazon aws-sdk-cpp on signed-char platforms","id":"CVE-2026-19643","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":6,"headline":"Potential URI resolution path traversal in the AWS SDK for PHP","id":"CVE-2023-51651","kev_date_added":null,"published":"2023-12-22"},{"cvss_score":5.5,"headline":"AWS SDK XML Parser XpathUtils.java XpathUtils server-side request forgery","id":"CVE-2022-4725","kev_date_added":null,"published":"2022-12-24"},{"cvss_score":4.3,"headline":"Exposure of unencrypted plaintext hash in github.com/aws/aws-sdk-go","id":"CVE-2022-2582","kev_date_added":null,"published":"2022-12-27"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"2026-08-13","vendors":["AWS"]},"summary":"A remote authenticated user can trigger heap memory corruption or crashes in applications using the AWS C++ SDK via crafted Base64 input.","url":"https://insights.sbomify.com/CVE-2026-19642/"}
