CVE-2018-1196 is a vulnerability of currently unknown severity. Spring Boot supports an embedded launch script that can be used to easily run the application as a systemd or init.d linux service. The script included with Spring Boot 1.5.9 and earlier and 2.0.0.M1 through 2.0.0.M7 is susceptible to a symlink attack which allows the "run_user" to overwrite and take ownership of any file on the same system. EPSS estimates a 1.23% chance of exploitation in the next 30 days.
