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.

Spring Boot's Mail auto-configuration does not enable hostname verification. Applications that set the relevant JavaMail property, such as spring.mail.properties.mail.smtp.ssl.checkserveridentity=true, are not affected.

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.

When an application is configured to use ApplicationPidFileWriter, a local attacker with write access to the PID file's location can corrupt one file on the host each time the application is started.

Affected: Spring Boot 4.0.0–4.0.5 (fix 4.0.6), 3.5.0–3.5.13 (fix 3.5.14), 3.4.0–3.4.15 (fix 3.4.16), 3.3.0–3.3.18 (fix 3.3.19), 2.7.0–2.7.32 (fix 2.7.33); PID file / symlink behavior (ApplicationPidFileWriter). Versions that are no longer supported are also affected per vendor advisory.
