Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-104002 in the wild and no public exploit code.\n\nAffected product: AWS powertools-lambda-python. 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-2026-104002/ (Markdown: https://insights.sbomify.com/CVE-2026-104002/index.md)","id":"CVE-2026-104002","markdown":"https://insights.sbomify.com/CVE-2026-104002/index.md","name":"CVE-2026-104002","record":{"aliases":["GHSA-3vxg-4xv2-jfh5"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"AWS Lambda Python library","requires_auth":"low_privilege","summary":"Attackers can read sensitive data intended to be masked due to fail-open error handling in the AWS Lambda Powertools data masking utility.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-390","name":"Detection of Error Condition Without Action"}],"description":"A fail-open error handling issue within the data masking utility of Powertools for AWS Lambda (Python) might allow actors to read sensitive field values that the application intended to mask. \n\nTo remediate this issue, users should upgrade to version 3.35.0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Fail-open error handling in the data masking utility in Powertools for AWS Lambda (Python)","id":"CVE-2026-104002","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Code injection in Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile \u0026 Restrict Content – ProfilePress","id":"CVE-2026-104003"},"packages":[],"prev":{"headline":"Slim SEO \u003c= 4.11.1 - Authenticated (Subscriber+) Arbitrary Shortcode Execution via 'Biographical Info' User Meta","id":"CVE-2026-104001"},"products":["powertools-lambda-python"],"published":"2026-10-01","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-09","vendors":["AWS"]},"summary":"Attackers can read sensitive data intended to be masked due to fail-open error handling in the AWS Lambda Powertools data masking utility.","url":"https://insights.sbomify.com/CVE-2026-104002/"}
