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.

In JetBrains Hub before 2025.3.119807 authentication bypass allowing administrative actions was possible

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.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed JetBrains Hub version
    Locate the Hub version through the administrative web interface (typically at /about or /api/system/info) or check the installation directory for a version manifest file
    Affected if The displayed version number is lower than 2025.3.119807
  2. Confirm Hub is network-accessible
    Verify the Hub web interface is reachable over HTTP/HTTPS from untrusted networks
    Affected if The administrative interface is exposed to the internet or untrusted internal networks without additional authentication proxies
  3. Check administrative session configuration
    Review Hub security settings to confirm whether default admin accounts exist with unchanged credentials or whether anonymous access is permitted
    Affected if Anonymous access is enabled or default administrative accounts remain configured with default credentials

You are affected if your installed JetBrains Hub version is lower than 2025.3.119807 and the administrative interface is network-accessible.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.
