# pgsty/minio Security Advisories
|
|
|
|
This document summarizes fork-specific security fixes and closely related upgrade-impacting security notes in `pgsty/minio`. It is intentionally narrower than a full changelog and focuses on release-impacting security behavior.

## Advisories since `RELEASE.2026-03-21T00-00-00Z`
|
|
|
|
| ID | Fixed by | Affected area | Remote exploitability | Summary | Upgrade / workaround notes |
|
|
| :-- | :-- | :-- | :-- | :-- | :-- |
|
|
| `CVE-2026-33322` | `d24f449e0` | OIDC STS (`AssumeRoleWithWebIdentity`, `AssumeRoleWithClientGrants`) | Yes | Closes JWT algorithm confusion by removing HMAC/shared-secret verification and requiring JWKS-backed verifier keys | Breaking change: providers issuing `HS256`, `HS384`, or `HS512` tokens for these STS flows must switch to JWKS-backed RSA or ECDSA signing before upgrading. `PS256` and `EdDSA` are not currently supported. |
|
|
| `CVE-2026-33419` | `3b950f8fa` | LDAP STS authentication | Yes | Prevents username enumeration by unifying unknown-user and bad-password responses and adds in-memory login throttling | Unknown users and invalid passwords now both return `400 InvalidParameterValue`. Rate limiting is per-node, in-memory, and not currently configurable. Follow-up hardening landed in `18b712d49`, `9e10f6d9a`, and `f44110890`. |
|
|
| `CVE-2026-34204` | `56fa63bfd` | Replication metadata handling | Yes | Blocks untrusted `X-Minio-Replication-*` headers from being smuggled into internal replication metadata and leaving objects unreadable | Upgrade any server that accepts untrusted `PutObject` or `CopyObject` requests, which in practice means almost any production server that accepts writes. |
|
|
| `CVE-2026-39414` | `3252d5b7f` | S3 Select oversized record handling | Yes | Rejects oversized CSV records and non-`simdjson` line-delimited JSON records with `OverMaxRecordSize` instead of buffering them unchecked | Split oversized JSON lines client-side if you rely on `simdjson` input paths until the fast path gains the same pre-check. |
|
|
| [CVE-2026-41145](https://github.com/advisories/GHSA-hv4r-mvr4-25vw) | `f444b6f37` | Unsigned-trailer PUT and multipart upload authentication | Yes | Closes the query-string authentication bypass in unsigned-trailer streaming requests | Upgrade if clients can reach object write endpoints using the `STREAMING-UNSIGNED-PAYLOAD-TRAILER` content-sha256 mode together with query-string SigV4 credentials. |
|
|
| [CVE-2026-40344](https://github.com/advisories/GHSA-9c4q-hq6p-c237) | `efb6e5b00` | Snowball auto-extract authentication | Yes | Verifies request authentication before tar extraction in Snowball unsigned-trailer flows | Upgrade if you use `PutObjectExtract` or Snowball uploads. |
|
|
| [CVE-2026-42600](https://github.com/advisories/GHSA-xh8f-g2qw-gcm7) | `73ac52472` | Internode `ReadMultiple` storage-REST endpoint | Yes (cluster-root JWT required) | Removes the unused endpoint that allowed path traversal outside configured drive roots | Upgrade distributed-erasure deployments. Single-node deployments do not register this route. |

|
| ID | Fixed by | Summary |
|
|
| :-- | :-- | :-- |

|
|
| `CVE-2026-39883` | `1869bd30b`, `e4fa06394` | Updates OpenTelemetry dependencies. |
|
|
| Upstream Go security fixes | [Go 1.26.5](https://go.dev/doc/devel/release#go1.26.5) | Bumps the required toolchain to Go 1.26.5, which includes security fixes to `crypto/tls` and `os`. |
|
|
| [GO-2026-6061](https://pkg.go.dev/vuln/GO-2026-6061) / [GHSA-hrxh-6v49-42gf](https://github.com/advisories/GHSA-hrxh-6v49-42gf) | gRPC `v1.82.1` | Updates gRPC to the first fixed version for vulnerabilities in the xDS RBAC authorization engine and HTTP/2 transport server. |
|
|
| [GO-2026-5970](https://pkg.go.dev/vuln/GO-2026-5970) / `CVE-2026-56852` | `x/text` `v0.39.0` | Updates `x/text` to the first fixed version for an infinite loop on invalid input. |

## Operationally significant security-related fixes

|
| Change | Fixed by | Summary |
|
|
| :-- | :-- | :-- |
|
|
| LDAP TLS regression | `ce1c537eb` | Restores TLS configuration propagation for `ldaps://` `DialURL()` connections so `MINIO_IDENTITY_LDAP_TLS_SKIP_VERIFY` and custom root CAs work again. |
