Overview

org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.

Affected versions of this package are vulnerable to Insecure Temporary File. A flaw was found in keycloak. Directories can be created prior to the Java process creating them in the temporary directory, but with wider user permissions, allowing the attacker to have access to the contents that keycloak stores in this directory. The highest threat from this vulnerability is to data confidentiality and integrity.
