Prior to RELEASE.2023-03-20T20-16-18Z, an attacker can use crafted requests to bypass metadata bucket name checking and put an object into any bucket while processing `PostPolicyBucket`. To carry out this attack, the attacker requires credentials with `arn:aws:s3:::*` permission, as well as enabled Console API access. This issue has been patched in RELEASE.2023-03-20T20-16-18Z. As a workaround, enable browser API access and turn off `MINIO_BROWSER=off`. \n"}], "lastModified": "2025-10-24T14:46:50.390", "cisaActionDue": "2023-10-10", "cisaExploitAdd": "2023-09-19", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:minio:minio:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "63CBB19F-80FF-4D6B-ADF3-7BD9768861D0", "versionEndExcluding": "2023-03-20t20-16-18z"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com", "cisaRequiredAction": "Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.", "cisaVulnerabilityName": "MinIO Security Feature Bypass Vulnerability"}
