Spring boot maven

So i just finished a java course, and i wanted to start learning spring boot. i followed intellij spring boot setup on youtube but it seems that it showes me the whitelabel window, when i visit localhost 8080. i checked pom and i realised that the spring web dependency is highlighted in yellow, and it's suggest me this when i hover over it "Provides transitive vulnerable dependency maven:org.yaml:snakeyaml:1.33." i dont know why but even if i set up a spring initializr maven project and open it in intellij i keep having the same issue please help
