| ------------- | ---
| Branch?       | master
| Bug fix?      | no
| New feature?  | yes
| BC breaks?    | no (except for people using FrameworkBundle without requiring symfony/symfony which should be pretty rare; and fixing this is easy by adding symfony/security-core and symfony/security-csrf explicitly)
| Deprecations? | no
| Tests pass?   | yes
| Fixed tickets | #15748 partially
| License       | MIT
| Doc PR        | n/a
