Description
Insecure temporary directory usage in frontend build functionality of com.vaadin:flow-server versions 2.0.9 through 2.5.2 (Vaadin 14.0.3 through Vaadin 14.5.2), 3.0 prior to 6.0 (Vaadin 15 prior to 19), and 6.0.0 through 6.0.5 (Vaadin 19.0.0 through 19.0.4) allows local users to inject malicious code into frontend resources during application rebuilds.
Affected versions
Maven
| Package | Vulnerable | Fixed in |
|---|---|---|
| com.vaadin:vaadin-bom | >= 14.0.3, < 14.5.3 |
14.5.3 |
| com.vaadin:vaadin-bom | >= 15.0.0, < 19.0.5 |
19.0.5 |
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 → 14.5.3

Weakness
CWE-379: Creation of Temporary File in Directory with Insecure Permissions
The product creates a temporary file in a directory whose permissions allow unintended actors to determine the file's existence or otherwise access that file.
How to prevent it
- Requirements: Many contemporary languages have functions which properly handle this condition. Older C temp file functions are especially susceptible.
- Implementation: Try to store sensitive tempfiles in a directory which is not world readable -- i.e., per-user directories.
- Implementation: Avoid using vulnerable temp file functions.
