### Description Symfony's `#[IsGranted('...')]`, `#[IsSignatureValid]`, and `#[IsCsrfTokenValid(...)]` attributes allow you to define a `methods: [...]` argument to only enforce these checks for the listed HTTP methods and skip them otherwise. E.g. an attribute defining `methods: ['GET']` would be ignored for a `HEAD` request. On the other hand, Symfony's router (and HTTP semantics generally) serves `HEAD` requests using the `GET` handler. Therefore, a controller protected by e.g. `#[IsGranted('ROLE_ADMIN', methods: ['GET'])]` can be reached via `HEAD` with the authorization check silently skipped. Even if the `HEAD` request won't get any response content, response headers leak (`Content-Length`, `Location`, custom headers). Also, the controller still executes and any side effects (DB writes, state changes) occur. ### Resolution When adding `GET` in the `methods` option of these attributes, Symfony now also include the `HEAD` method automatically. The patch for this issue is available [here](https://github.com/symfony/symfony/commit/fa8d5c67aa4b22c9656e3fd7d5c3aa59865bf838) for branch 7.4. ### Credits Symfony would like to thank Claude Mythos Preview (via Project Glasswing) for reporting the issue and Alexandre Daubois for fixing it.
