Information Disclosure in Guava

  • Disclosed: 25.03.2021
  • Updated: 11.10.2026 13:19

A temp directory creation vulnerability exists in Guava prior to version 32.0.0 allowing an attacker with access to the machine to potentially access data in a temporary directory created by the Guava com.google.common.io.Files.createTempDir(). The permissions granted to the directory created default to the standard unix-like /tmp ones, leaving the files open. Maintainers recommend explicitly changing the permissions after the creation of the directory, or removing uses of the vulnerable method.
