Malformed erasure layouts can divide by zero, while negative part sizes collapse expected shard sizes to zero and make truncated data appear healthy. Boundary validation alone is insufficient because poisoned metadata may already exist on disk or arrive through local heal paths.
Reject non-positive block sizes at the sole Erasure constructor, guard the metadata arithmetic helpers and rebalance calculation, refuse negative part sizes before persistence, and make CheckParts and VerifyFile reject previously stored poison. Tests cover both shard-size implementations, construction, persistence, local verification, and the wire boundary.

Storage REST request bodies and Grid RPC frames bypass the HTTP validity middleware, allowing wire-supplied paths and malformed FileInfo values to reach xlStorage unchecked.
Wrap the remotely exposed StorageAPI with a guard that covers every path-bearing method, including nested metadata fields. Reject traversal and destructive volume-root aliases before path cleaning can erase them, and validate erasure geometry and part sizes at the same wire boundary. Keep a raw-volume check in getVolDir for peer-S3 calls that bypass the wrapper.
Reflection, fuzz, traversal, peer-S3, compatibility, and malformed-erasure tests pin the complete method surface and prove that legal object names remain accepted.

WithDeadline runs its work function on a goroutine of its own, so a panic
inside it is reachable by no recover() the caller can install: net/http
and internal/grid each recover only on the goroutine they own. Left
unhandled it terminates the process, which turns any malformed internode
payload that trips a bug in work() into a remote node kill.
Eleven call sites run wire-derived storage work through this path. The
project already recovers panics at both request boundaries; this extends
the same policy to the one goroutine those recovers cannot reach.
Stack dumps are capped over the process lifetime. The panic is by
definition reachable from untrusted input, so writing a full stack per
occurrence would trade a node kill for unbounded log amplification, one
small request each. The error is returned every time regardless, so the
caller's own rate-limited logging still sees each occurrence.
Inherited from upstream; the fork added no lines to this path.

hash.Checksum.AddPart returned before seeding the accumulator when the
part was empty, so a multipart object with no content at all ended up
with no checksum instead of the checksum of zero bytes. Completing such
an upload failed with XAmzContentChecksumMismatch when the client
supplied the correct object checksum, and stored an empty checksum when
it did not.
Run the type check and the first checksum seeding before the zero size
early return. Appending zero bytes still leaves an existing accumulator
unchanged, so only the all empty case changes: a zero length part
followed by content already merged correctly, because prepending no bytes
does not alter a CRC.
AddPart has a single production caller, the multipart completion path, and
its part checksum type is derived from the upload's own checksum type, so
the type check now reached for zero sized parts cannot fire there.
Add a table test over CRC32, CRC32C and CRC64NVME covering every position
an empty part can take, and an API level zero length full object upload
that exercises the persisted AppendTo/ReadCheckSums round trip.

CompleteMultipartUpload compared the per-part checksum taken from the
request body against the stored part checksum unconditionally, so a
client that sent only PartNumber and ETag for each part failed with
InvalidPart.
AWS S3 requires part level checksums in the completion body only for
composite checksum types. For full object types the client sends the
object level checksum in the request headers instead and does not retain
per-part values - that is the point of FULL_OBJECT. Reproduced with
boto3 1.43.58: it puts x-amz-checksum-crc32 on each UploadPart and the
full object checksum on the completion headers, but emits only ETag and
PartNumber in the completion body. A caller could only get such an upload
through by collecting the per-part checksums from the UploadPart
responses and echoing them back, which is exactly the bookkeeping
FULL_OBJECT exists to avoid and which no off-the-shelf SDK call does.
minio-go does echo them, which is why mc never hit this.
Treat the part checksum as optional when the upload declared a full
object checksum type and the client sent no part checksum at all. A part
carrying any checksum is still validated against the stored one -
including one sent under the wrong algorithm, which cannot match and is
rejected - composite uploads keep requiring a checksum for every part,
and the merged object checksum is still computed from the server stored,
upload time validated part checksums, never from client supplied values,
so integrity is unchanged.
Covered by API level tests over CRC32, CRC32C and CRC64NVME on both the
single drive and erasure backends, with guards for a wrong object
checksum, a wrong part checksum, a part checksum under another algorithm,
a mix of present and omitted part checksums, an absent object checksum,
and composite uploads still requiring every part checksum.

Replace Georg Mangold's console fork (v1.9.1) with pgsty/silo-console
at the v2.0.0 release, Pigsty's maintained console carrying the SILO
identity, the redesigned and hardened web app, and regenerated embedded
assets. The fork keeps the upstream github.com/minio/console module
path without a /v2 suffix, so the replace pins v2.0.0's tagged commit
(b952a120) as a pseudo-version rather than the tag itself.
highwayhash v1.0.4 and go-m1cpu v0.2.2 follow from the new console's
requirements; the previous console resolved a v1.0.4 pre-release and
v0.2.1. Full-tree build verified against the new pin.

thrift 0.23.0 compares an int against math.MaxUint32, which does not
compile on 32-bit platforms and has broken linux/arm and linux/386
builds since the 2026-06-18 dependency refresh; 0.24.0 carries the
upstream fix. The library only reaches us through fraugster/parquet-go
for S3 Select, whose decode tests still pass.
go-systemd v22.7.0 moved CLOCK_MONOTONIC into a file built for every
unix platform and no longer compiles on NetBSD. Pin v22.6.0 with a
replace directive - a plain require cannot hold because Console pulls
v22.7.0 back in through MVS - until upstream ships the fix. The server
only consumes daemon.SdNotify, which both versions provide.

Update the module Go directive and release Docker build images from Go 1.26.2 to Go 1.26.4 so local, CI, hotfix, and release builds use the same patched toolchain.
Keep ordinary Go module requirements and replacements unchanged; this intentionally avoids a third-party dependency refresh while allowing container system packages to refresh through the newer golang Alpine base image and existing apk resolution.
Update the security advisory index to record the Go 1.26.4 toolchain bump alongside the earlier Go 1.26.2 security update.
Verified with go build ./..., go vet ./cmd/, and focused cmd tests. go mod tidy -diff was attempted as a read-only dependency drift check but could not complete because proxy.golang.org timed out while fetching uncached transitive test modules.

The internode storage-REST ReadMultiple endpoint (/rmpl) joined
attacker-controlled Bucket/Prefix/Files into a filesystem path with no
validation, letting a peer with internode credentials read files outside
the drive root (GHSA-xh8f-g2qw-gcm7).
ReadMultiple has had no production caller since upstream #20390 removed
the last one (listParts) in Sep 2024; multipart now uses ReadParts (/rps).
Following the upstream fix, remove the whole API instead of validating
paths: route constant and registration, server handler, REST client
wrapper, the StorageAPI/xlStorage/xlStorageDiskIDCheck methods, the
storageMetricReadMultiple metric, and the ReadMultipleReq/Resp datatypes.
Regenerated the msgp and stringer outputs; storageRESTVersion stays at v63.

Remove the per-username LDAP STS throttle bucket and keep the limiter keyed only by source IP. A username bucket is shared across all clients and lets one source keep a known account's bucket drained with bad-password attempts, locking the legitimate user out before LDAP bind.
For trusted proxies, stop trusting the left-most forwarded address. Resolve X-Forwarded-For right-to-left, skip trusted proxy hops, reject catch-all trusted-proxy CIDRs, and intentionally ignore RFC 7239 Forwarded for this security-sensitive bucket. Document that X-Real-IP is trusted verbatim and must be overwritten by the trusted proxy, not passed through from clients.
Update focused limiter, source-IP, trusted-proxy, and LDAP config tests to cover source-only buckets, spoofed appended XFF, multi-hop trusted proxies, Forwarded fallback, catch-all rejection, and the X-Real-IP deployment contract.

Allows the trackingResponseWriter to properly proxy flush
requests to the underlying http.Flusher. This ensures
compatibility with streaming responses.
Update the STS, security, select, and Docker documentation to reflect the recent hardening work, including LDAP STS throttling details, OIDC JWT verification changes, and the new pgsty-specific security policy and advisory index.
Rewrite repository and raw-document links that still pointed at minio/minio so the docs consistently reference pgsty/minio instead.
The core idea is to keep the documentation aligned with the fork's actual security behavior, ownership, and upgrade guidance without mixing in unrelated code changes.
Prevent LDAP STS reservation cancel paths from over-crediting rate-limit buckets by capping refill and refund capacity against in-flight reservations.
Add an explicit trusted-proxy allowlist for LDAP STS source bucketing, prefer clean X-Real-IP values on trusted peers, and extend tests/docs for the new behavior.
Use the socket peer address for LDAP STS per-IP rate limiting instead of the generic forwarded-header-aware helper. This keeps the security-sensitive rate-limit key from trusting spoofable X-Forwarded-For, X-Real-IP, and Forwarded headers while leaving the rest of the source-IP behavior unchanged.
Add focused regression coverage for RemoteAddr parsing, header spoofing, and peer-address bucket selection.
Update go.mod and all golang build images from 1.26.1 to 1.26.2 to pick up the upstream 2026-04-07 security release.

Track issue #28 / GHSA-9c4q-hq6p-c237 as fake CVE-2026-40028. Close the Snowball auto-extract auth gap in PutObjectExtractHandler by treating authTypeStreamingUnsignedTrailer the same as ordinary PUTs: honor X-Amz-Decoded-Content-Length, initialize newUnsignedV4ChunkedReader(), and verify the SigV4 request before any tar bytes reach untar(). This removes the forged-signature write primitive that let a single request fan out into arbitrary extracted object creation.
Add regression coverage for forged-signature Snowball unsigned-trailer writes, anonymous Snowball requests against non-public buckets, and legitimate signed Snowball extraction with trailing CRC32 trailers. Validate the new tests against the vulnerable parent and patched tree, and confirm with containerized before/after smoke runs that the exploit succeeds pre-fix, fails post-fix, and normal signed Snowball uploads still extract correctly.

Track issue #27 / GHSA-hv4r-mvr4-25vw as fake CVE-2026-40027. Close the unsigned-trailer trust flaw that let query-string credentials skip signature verification in PutObject and PutObjectPart by moving presigned rejection and SigV4 verification into newUnsignedV4ChunkedReader(), so authTypeStreamingUnsignedTrailer can no longer silently downgrade query auth into an anonymous body read.
Add focused regression coverage for forged query-string-only unsigned-trailer PUTs and multipart uploads, mixed header/query auth rejection, and anonymous unsigned-trailer writes that remain allowed only when bucket policy explicitly permits them. Validate the new tests against the vulnerable parent and confirm with before/after live-server runs that presigned unsigned-trailer attacks are rejected while legitimate header-authenticated and policy-driven flows still work.

Enforce the 1 MiB maxCharsPerRecord limit while splitting CSV and line-delimited JSON input so oversized records are rejected before they can be buffered and parsed.
Return OverMaxRecordSize for these failures instead of collapsing them into InternalError, and preserve splitter errors in the JSON worker so oversized-record failures are not lost after successful partial decode.
Close the replication-header trust flaw that allowed ordinary PutObject and CopyObject requests to smuggle X-Minio-Replication-* headers into X-Minio-Internal-* SSE metadata and write objects into an unreadable state. Stop accepting replication-only metadata in the default extraction path, restore it only after a trusted replication write has passed ReplicateObjectAction, and tighten CopyObject by sanitizing replication-only request headers before metadata, precondition, and SSE-C source handling consume them. Also gate replica status writes on the same trusted replication path and restore replication SSE metadata in multipart and snowball upload flows so legitimate replication continues to work.
Add focused regression coverage for untrusted PUT and COPY header poisoning at the handler layer, plus helper tests for trusted vs untrusted metadata extraction and CopyObject header sanitization. Validate the new tests against both the patched tree and the vulnerable HEAD baseline, and confirm with live server before/after runs that malicious PUT/COPY requests no longer turn objects unreadable.

ignored (x509: certificate signed by unknown authority).
Pin four dependencies to avoid breaking changes introduced in 5abd9a80f:
- go-ldap/ldap/v3 v3.4.12: v3.4.13 rewrote GetLDAPError() internals
- IBM/sarama v1.45.1: v1.46.0 changed Kafka protocol version negotiation
- lib/pq v1.10.9: v1.11.0 treats nil []byte as NULL and drops PG <14
- etcd v3.6.8: stay on intermediate version per policy
