CVE-2026-40344

MinIO is a high-performance object storage system. Starting in RELEASE.2023-05-18T00-05-36Z and prior to RELEASE.2026-04-11T03-20-12Z, an authentication bypass vulnerability in MinIO's Snowball auto-extract handler PutObjectExtractHandler allows any user who knows a valid access key to write...

Authentication Bypass

MinIO is vulnerable to Authentication Bypass. The vulnerability is due to missing signature verification for authTypeStreamingUnsignedTrailer requests in the Snowball auto-extract handler, which allows an attacker with knowledge of a valid access key to upload arbitrary objects without providing ...
