SILO 20260618 Released

LDAP STS hardening, complete S3 Select record limits, ReadMultiple removal, Go 1.26.4, and security dependency updates.
By Ruohang Feng |

Published: 2026-06-18 · Version: RELEASE.2026-06-18T00-00-00Z

This release is a security and dependency-maintenance update for the pgsty/minio fork. It hardens LDAP STS throttling, completes S3 Select oversized-record enforcement, removes the obsolete ReadMultiple internode storage-REST API, upgrades the Go build baseline to 1.26.4, and refreshes Go module dependencies to pick up additional third-party security fixes.

Major Changes

  • Remove the obsolete ReadMultiple storage-REST API: the legacy /rmpl internode endpoint is removed rather than patched in place, including its route, handler, client wrapper, storage interfaces, xlStorage methods, generated datatypes, and related metric. No production caller is expected after upstream multipart handling moved to ReadParts, but clusters should still run a consistent release during rolling upgrades.
  • Complete S3 Select oversized-record enforcement: JSON Lines input now uses the bounded reader path, so oversized records are rejected consistently instead of bypassing limits on SIMD-capable CPUs. S3 Select stream errors now preserve the intended error code and wrap JSON parser failures as JSONParsingError.
  • Harden LDAP STS rate-limit source bucketing: throttling is now keyed only by source IP, avoiding username-shared buckets that could be drained by one client to lock out a legitimate user. Trusted-proxy handling now resolves X-Forwarded-For from right to left, rejects catch-all trusted-proxy CIDRs, ignores RFC 7239 Forwarded, and documents the X-Real-IP deployment contract.
  • Refresh the Go runtime and module baseline: release, hotfix, goreleaser, and old-CPU Docker builds now use golang:1.26.4-alpine; go.mod is updated to Go 1.26.4; and dependencies are refreshed across NATS, Prometheus, Azure SDK, Apache Thrift, gRPC, OpenTelemetry, Google API/auth, Go x/*, and related transitive libraries.

Direct Security Fixes

  • CVE-2026-42600: remove the obsolete ReadMultiple storage-REST API to close the legacy internode file-read path exposed through /rmpl.
  • CVE-2026-39414: complete oversized S3 Select record enforcement for JSON Lines inputs and preserve correct S3 Select error semantics.
  • CVE-2026-33419: further harden LDAP STS rate-limit accounting and trusted-proxy source-IP handling.

Dependency Security Updates

  • Update github.com/Azure/go-ntlmssp from v0.1.0 to v0.1.1, fixing CVE-2026-32952, where malformed NTLM challenges could panic a Go process.
  • Update github.com/apache/thrift from v0.22.0 to v0.23.0, fixing CVE-2026-41602 in the Go TFramedTransport implementation.
  • Update github.com/nats-io/nats-server/v2 from v2.11.1 to v2.11.15, absorbing the NATS 2.11.x security patch line. Notable fixes include pre-auth WebSocket and leafnode denial-of-service issues, MQTT authorization issues, JetStream management API authorization hardening, credential exposure fixes, and request identity-spoofing fixes, including CVE-2026-27889, CVE-2026-29785, CVE-2026-33217, CVE-2026-33218, CVE-2026-33222, and CVE-2026-33247.
  • Update github.com/prometheus/prometheus from v0.310.0 to v0.311.3, absorbing Prometheus security fixes for remote-read denial of service, stored XSS in UI surfaces, and remote-write configuration secret exposure, including CVE-2026-42154, CVE-2026-44903, CVE-2026-42151, and CVE-2026-40179.
  • Upgrade the release build baseline through Go 1.26.4 and refresh supporting Go module families, including golang.org/x/crypto, golang.org/x/net, golang.org/x/sys, golang.org/x/text, google.golang.org/grpc, and OpenTelemetry. These updates keep the fork aligned with patched upstream dependency baselines even where the previously pinned version was already past the specific public advisory range.

SILO 20260417 Released

Security hardening across OIDC, LDAP STS, S3 Select, replication metadata, unsigned-trailer flows, and the Go toolchain.
By Ruohang Feng |

Published: 2026-04-17 · Version: RELEASE.2026-04-17T00-00-00Z

This release focuses on security hardening and compatibility tightening. It bundles fixes across OIDC, LDAP STS, S3 Select, replication metadata handling, unsigned-trailer flows, the Snowball upload path, and multiple dependency- and Go toolchain-related security issues, while also incorporating the LDAP TLS regression fix and a cleanup of community-fork documentation.

Major Changes

  • Tighten the identity-authentication flow: OIDC / WebIdentity now accepts only asymmetrically signed ID Token values backed by the IdP JWKS; symmetrically signed tokens such as HS256 are no longer accepted. LDAP STS also now hides the distinction between unknown-user and bad-password failures to reduce username-enumeration risk.
  • Update LDAP STS rate limiting: limits now apply to both source IP and normalized username, and successful requests no longer consume quota incorrectly. By default MinIO now uses only the socket peer address as the source and no longer trusts X-Forwarded-For, X-Real-IP, or Forwarded; to rate-limit by real client IP, configure MINIO_IDENTITY_LDAP_STS_TRUSTED_PROXIES explicitly.
  • Make upload and write paths stricter: presigned query parameters can no longer be combined with unsigned-trailer PUT or multipart uploads. Snowball auto-extract now also performs full signature validation on the unsigned-trailer path and rejects anonymous or forged-signature requests.
  • Prevent replication metadata spoofing: internal X-Minio-Replication-* headers attached to ordinary PUT / COPY requests are now rejected or ignored, and only trusted replication flows may write the related internal metadata.
  • Clarify S3 Select error semantics: oversized CSV and line-delimited JSON records now return OverMaxRecordSize directly instead of the generic InternalError; clients or alerting rules that depend on the old error code should be adjusted.
  • Upgrade the runtime and dependency baseline: fix the regression where ldaps:// did not correctly apply TLS settings, replace minio/pkg/v3 with pgsty/minio-pkg/v3, and pin several critical dependencies that are prone to breaking changes. The release also upgrades go-jose, go.opentelemetry.io, and Go 1.26.2 to unify the build and release baseline.
  • Refresh documentation and security guidance: update SECURITY.md, VULNERABILITY_REPORT.md, docs/sts/ldap.md, and related documents, add a security advisory index, and switch upstream minio/minio references in the security guidance over to pgsty/minio.

Fixed CVEs

  • CVE-2026-34986: upgrade go-jose to v4.1.4 and fix known security issues in the JWT / JOSE dependency chain.
  • CVE-2026-39883: upgrade the go.opentelemetry.io dependency stack to fix the PATH-hijacking risk.
  • CVE-2026-33322: restore the strict JWKS-only OIDC JWT verification path to block keyring injection and algorithm-confusion risk.
  • CVE-2026-33419: systematically harden LDAP STS authentication, rate limiting, source-address identification, and accounting logic across four follow-up fixes.
  • CVE-2026-34204: reject injection of X-Minio-Replication-* metadata by untrusted requests to prevent objects from being written with invalid replication state.
  • CVE-2026-39414: reject oversized S3 Select records early to avoid continued buffering and parsing of abnormal inputs.
  • GHSA-hv4r-mvr4-25vw: close the unsigned-trailer query-auth bypass.
  • GHSA-9c4q-hq6p-c237: harden unsigned-trailer authentication and signature validation in Snowball auto-extract scenarios.
  • CVE-2026-32280, CVE-2026-32281, and CVE-2026-32283: upgrade Go to 1.26.2 and absorb the upstream toolchain and stdlib security fixes.

By Ruohang Feng |

Published: 2026-02-14 · Version: RELEASE.2026-02-14T12-00-00Z

This early infrastructure-focused community release restores the embedded Console, introduces GitHub CI/CD, and lifts the Go baseline to 1.26.0, which also absorbs a batch of security fixes from the older toolchain generation.

Major Changes

  • Restore the embedded Console and refresh the README to clarify the community fork position.
  • Add GitHub CI/CD workflows as the base for automated builds and multi-platform delivery.
  • Add quick links for docs, Docker, the GitHub repository, and installation through the pig package manager.

Fixed CVEs

These issues were absorbed as part of the Go 1.25.5 -> 1.26.0 upgrade:

  • CVE-2025-68121: crypto/tls could incorrectly accept mutated CA configuration during session resumption.
  • CVE-2025-61730: TLS 1.3 could process handshake messages incorrectly across encryption-level boundaries.
  • CVE-2025-61726: net/url query parsing could be abused for memory exhaustion.

SILO 20251203 Released

The first community packaging and distribution baseline, with APK, DEB, and RPM artifacts.
By Ruohang Feng |

Published: 2025-12-15 · Version: RELEASE.2025-12-03T12-00-00Z

This is the earliest traceable community release. Its purpose is to establish the community packaging and distribution baseline rather than to deliver incremental fixes over an earlier community release.

Major Changes

  • Build the community packaging flow around minio/pkger.
  • Choose a maintenance-mode upstream MinIO baseline as the starting point for the community-maintained fork.
  • Produce the first apk, deb, and rpm artifacts for ongoing community releases.

Fixed CVEs

  • This is the first community release. The GitHub Release does not provide a delta-style security-fix list against an earlier community version, and this page does not attempt to reconstruct the full historical CVE delta against the upstream maintenance baseline.
