AI-suggested

Apply the official patches provided by Spring Boot by upgrading to fixed versions: 2.7.33, 3.3.19, 3.4.16, 3.5.14, or 4.0.6. Since a patch is available and the vulnerability is fixed in these versions, upgrading is the recommended mitigation. Restrict local write access to the PID file directory as a temporary measure if patching is not immediately possible.

Description

A vulnerability in Spring Boot's ApplicationPidFileWriter allows a local attacker with write access to the PID file location to corrupt a file on the host each time the application starts. This affects multiple Spring Boot versions prior to fixed releases. The issue involves following symlinks at predictable default locations, enabling file corruption.
