Description
Non-constant-time comparison of CSRF tokens in endpoint request handler in com.vaadin:flow-server versions 3.0.0 through 5.0.3 (Vaadin 15.0.0 through 18.0.6), and com.vaadin:fusion-endpoint version 6.0.0 (Vaadin 19.0.0) allows attacker to guess a security token for Fusion endpoints via timing attack.
Affected versions
Maven
| Package | Vulnerable | Fixed in |
|---|---|---|
| com.vaadin:vaadin-bom | >= 19.0.0, < 19.0.1 |
19.0.1 |
| com.vaadin:vaadin-bom | >= 15.0.0, < 18.0.7 |
18.0.7 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
com.vaadin:vaadin-bom Maven → 19.0.1

Weakness
CWE-208: Observable Timing Discrepancy
