Detailsinfo

A vulnerability has been found in RustFS up to 1.0.0-beta.11 and classified as problematic. This vulnerability affects some unknown processing of the file rustfs/src/storage/access.rs of the component Policy Evaluation. The manipulation with an unknown input leads to a access control vulnerability. The CWE definition for the vulnerability is CWE-284. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. As an impact it is known to affect confidentiality. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability was named CVE-2026-73290 since 08/11/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1068 by the MITRE ATT&CK project.

Upgrading to version 1.0.0-beta.12 eliminates this vulnerability.
