Descripción técnica

RustFS is a distributed object storage system built in Rust. From 1.0.0-alpha.64 until 1.0.0-rc.1, RustFS external OPA authorization enabled by RUSTFS_POLICY_PLUGIN_URL in crates/iam/src/sys.rs sets PreparedIamAuth.needs_existing_object_tag incorrectly for PreparedIamMode::Opa, causing maybe_merge_object_tag_conditions to omit s3:ExistingObjectTag/* values and allowing authenticated users to bypass tag-based policy restrictions. This issue is fixed in version 1.0.0-rc.1.

CVE-2026-732905.3 MED

—

———RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.12, an anonymous ListObjectVersions request in rustfs/src/storage/access.rs that lacks a direct bucket-policy grant falls back to an s3:ListBucket check and returns before the policy_allowed path applies deny_anonymous_table_data_plane_if_needed and RestrictPublicBuckets, so a bucket that permits anonymous listing can continue exposing version listings after an operator enables the public-access control. The bypass affects GET /<bucket>?versions= and can disclose object version metadata even though equivalent GetObject requests are denied. This issue is fixed in version 1.0.0-beta.12.6h CVE-2026-732898.1 ALT

———RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.12, RustFS evaluates the ForAllValues: and ForAnyValue: set qualifiers with the negated string operators StringNotEquals, StringNotEqualsIgnoreCase, StringNotLike, ArnNotEquals, and ArnNotLike using each other's semantics because crates/policy/src/policy/function/string.rs negates the aggregate result after eval or eval_like instead of negating each request-value predicate before quantification. Partially overlapping policy and request value sets can therefore make an Allow condition grant access to an excluded principal or make a Deny guardrail fail, including policies based on jwt:groups and jwt:roles; absent keys also receive the opposite ForAllValues: and ForAnyValue: behavior. This issue is fixed in version 1.0.0-beta.12.7h CVE-2026-732868.1 ALT

———RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.12, RustFS get_condition_values folds attacker-controlled request headers from HeaderMap into server-derived userid, username, principaltype, groups, versionid, signatureversion, jwt:, and ldap: condition keys, allowing authenticated callers to satisfy identity-based policy conditions. This issue is fixed in version 1.0.0-beta.12.6h CVE-2026-732656.5 MED

———RustFS is a distributed object storage system built in Rust. RustFS authorizes explicit versionId reads in GetObject, CopyObject sources, and UploadPartCopy sources with s3:GetObject instead of s3:GetObjectVersion, allowing principals without historical-version permission to disclose known historical object content. This issue is fixed in version 1.0.0-beta.11.7h CVE-2026-687554.3 MED

———Docker Sandboxes (sbx) applies the read-only intent of a runtime host mount to the in-guest container bind only: the underlying virtio-fs host-edge grant is added to the sandbox's policy-share allowlist with no access mode. The directory stays writable at its shared-export path, so unprivileged code inside the sandbox can derive that path and write to a host directory the operator attached read-only.7h
