An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-31489 exists.\n\nAffected packages and fixed versions:\n- github.com/minio/minio (Go): affected all versions; fixed in 0.0.0-20250403145552-8c70975283f9\n- github.com/minio/minio (Go): affected all versions; fixed in 0.0.0-20250403145552-8c70975283f9\n- github.com/minio/minio (Go): affected all versions; fixed in 0.0.0-20250403145552-8c70975283f9\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-2025-31489/ (Markdown: https://insights.sbomify.com/CVE-2025-31489/index.md)","id":"CVE-2025-31489","markdown":"https://insights.sbomify.com/CVE-2025-31489/index.md","name":"CVE-2025-31489","record":{"aliases":["GHSA-wg47-6jq2-q2hh","GO-2025-3594"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Object storage server","requires_auth":"none","summary":"Attackers with WRITE permissions can upload arbitrary objects by bypassing signature validation, requiring prior knowledge of access keys and bucket names.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"MinIO is a High Performance Object Storage released under GNU Affero General Public License v3.0.
