An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-28432 and fix it if it is affected.\n\nWhat it is: CVE-2023-28432 is a high-severity vulnerability in minio, published on 22 Mar 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2023-28432 in the wild since at least 21 Apr 2023.\n\nAffected product: minio. 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-2023-28432/ (Markdown: https://insights.sbomify.com/CVE-2023-28432/index.md)","id":"CVE-2023-28432","markdown":"https://insights.sbomify.com/CVE-2023-28432/index.md","name":"CVE-2023-28432","record":{"aliases":["GHSA-6xvq-wj2x-3h3q"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"MinIO object storage","requires_auth":"none","summary":"Attackers can retrieve sensitive environment variables, including root credentials, from MinIO cluster deployments, leading to potential unauthorized access.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"minio","vendor":"minio"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Minio is a Multi-Cloud Object Storage framework.
