CVE-2026-45041
RustFS is a distributed object storage system built in Rust.
Overview
CVE-2026-45041 is a known-severity vulnerability. It was published on May 28, 2026.
Technical description
RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, crates/appauth/src/token.rs ships a 2048-bit RSA private key as a string constant named TEST_PRIVATE_KEY and uses it in production via parse_license() to "verify" license tokens. Because the key is embedded in every published source release and binary, anyone who can read the repository or extract it from the binary can mint arbitrary license tokens (any subject, any expiration). When the license Cargo feature is enabled, this defeats the entire license-enforcement mechanism. This vulnerability is fixed in 1.0.0-beta.2.

How can CyberStrike help with CVE-2026-45041?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-45041 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.
