Summary
Spring Boot's PID file write follows symlinks at predictable default path
Details
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.
