Detailsinfo

A vulnerability was found in RustFS up to 1.0.0-beta.1. It has been declared as problematic. This vulnerability affects the function parse_license of the file crates/appauth/src/token.rs of the component License Cargo Feature. The manipulation with an unknown input leads to a hard-coded key vulnerability. The CWE definition for the vulnerability is CWE-321. The use of a hard-coded cryptographic key significantly increases the possibility that encrypted data may be recovered. As an impact it is known to affect integrity. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability was named CVE-2026-45041 since 05/08/2026. 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 T1600.001 by the MITRE ATT&CK project.

Upgrading to version 1.0.0-beta.2 eliminates this vulnerability.
