CVE-2022-25259
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 · uneditedJetBrains Hub before 2021.1.14276 was vulnerable to reflected XSS.
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 · moderate confidenceJetBrains Hub before version 2021.1.14276 contains a reflected cross-site scripting (XSS) vulnerability. This occurs when user-supplied input is improperly validated or encoded before being reflected back in web responses, allowing an attacker to inject malicious scripts that execute in the context of a victim's browser.

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 JetBrains Hub installationCheck if JetBrains Hub is running in your environment by accessing the Hub web interface or reviewing running services on your serverAffected if JetBrains Hub is present and running
-
Locate the installed version numberAccess the Hub web interface and navigate to the Administration or About section to view the version, or check startup logs for version informationAffected if You cannot determine the version from the UI or logs
-
Compare against affected versionCompare your installed version to the threshold 2021.1.14276 - note that only versions before this number are affectedAffected if Your installed version is lower than 2021.1.14276 (for example, 2021.1.14000 or any 2020.x release)
-
Verify XSS exposureThis is a reflected XSS vulnerability - determine if your Hub instance accepts and reflects user-supplied input in web responses without proper encodingAffected if The reflected XSS condition exists in your specific configuration and usage patterns
You are affected if JetBrains Hub is installed and the running version is lower than 2021.1.14276.

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 · scoped2021.1.14276
Upgrade JetBrains Hub to version 2021.1.14276 or later. If upgrading is not immediately feasible, implement input validation and output encoding at application entry points, and consider deploying a WAF as a temporary mitigation layer.
2021.1.14276 or later
- Stop the JetBrains Hub service
- Back up the Hub database and configuration files
- Download JetBrains Hub version 2021.1.14276 or later from the official JetBrains website (jetbrains.com)
- Install the new version following the standard upgrade procedure
- Verify the upgrade was successful by checking the Hub version in the administration UI
