CVE-2026-45043
RustFS is a distributed object storage system built in Rust.
Overview
CVE-2026-45043 is a known-severity vulnerability. It was published on May 29, 2026.
Technical description
RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, improper validation in the PUT /rustfs/admin/v3/import-iam endpoint allows a user with ImportIAMAction to create service accounts under arbitrary parent identities, including the root user (minioadmin). The endpoint accepts attacker-controlled parent, claims, accessKey, and secretKey values without enforcing privilege boundaries or sanitization. This enables privilege escalation to full administrative access using a persistent, attacker-defined credential. This vulnerability is fixed in 1.0.0-beta.2.

How can CyberStrike help with CVE-2026-45043?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-45043 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
