CVE-2026-47136
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedRustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, the RustFS console endpoint GET /rustfs/console/license returns parsed license metadata without requiring authentication. The endpoint is registered on the console listener and returns JSON containing license information such as the license subject and expiration timestamp. Any client that can reach the console listener can query this endpoint without credentials. This vulnerability is fixed in 1.0.0-beta.2.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe RustFS console endpoint GET /rustfs/console/license exposes license metadata including the license subject and expiration timestamp without requiring authentication. Any client that can reach the console listener can query this endpoint to retrieve sensitive licensing information.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if RustFS is runningCheck for running RustFS processes or services, or identify if port 8080 (default console port) is listening. Commands: 'ps aux | grep rustfs' or 'netstat -tlnp | grep 8080'Affected if RustFS process is running and the console port is open
-
Determine installed RustFS versionCheck the version of the installed RustFS binary or container image. Commands: 'rustfs --version' or 'docker images | grep rustfs'Affected if Version is before 1.0.0-beta.2 (vulnerable)
-
Test console license endpoint accessibilitySend an unauthenticated HTTP GET request to the console license endpoint. Command: 'curl http://<host>:8080/rustfs/console/license'Affected if Endpoint returns license metadata (subject, expiration) without requiring authentication
-
Verify network exposure of consoleCheck if the console listener is bound to 0.0.0.0 or an unrestricted interface. Inspect RustFS configuration files or running process environment variables for console bind addressAffected if Console is accessible from untrusted network segments (not localhost or restricted VLAN)
User is affected if RustFS version is before 1.0.0-beta.2 AND the /rustfs/console/license endpoint returns license data without authentication
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade RustFS to version 1.0.0-beta.2 or later, which includes authentication requirements for the license endpoint. Until upgraded, restrict network access to the console listener.
1.0.0-beta.2
- Upgrade RustFS to version 1.0.0-beta.2 or later to resolve the authentication bypass vulnerability
- After upgrading, verify that the /rustfs/console/license endpoint now requires authentication before returning license metadata
- If using automated build/deployment tools, update the version specification in your dependency configuration to ^1.0.0-beta.2 or the latest stable release
