CVE-2026-41001: Spring Boot: Predictable Temp Directory in Artemis Auto-configuration

June 11, 2026 (updated August 21, 2026)

Spring Boot’s ArtemisEmbeddedConfigurationFactory uses a fixed, static path for the embedded Artemis message broker’s data directory when no explicit path is configured. A local attacker on the same host can pre-create this predictable directory or place a symlink before the application starts.

Affected versions: Spring Boot 4.0.0 through 4.0.6; 3.5.0 through 3.5.14; 3.4.0 through 3.4.16; 3.3.0 through 3.3.19; 2.7.0 through 2.7.33.
