The 5.8 migration guide contains several steps for

ifndef::spring-security-version[]
|
|
exploit protection migrations when updating to 6.0.
|
|
endif::[]
|
|
You are encouraged to follow those steps first.
|
|
|
|
The following steps relate to how to finish migrating exploit protection support.
|
|
|
|
== Defer Loading CsrfToken
|
|
|
|
In Spring Security 5.8, the default `CsrfTokenRequestHandler` for making the `CsrfToken` available to the application is `CsrfTokenRequestAttributeHandler`.
|
|
The default for the field `csrfRequestAttributeName` is `null`, which causes the CSRF token to be loaded on every request.
|
|
|
|
In Spring Security 6, `csrfRequestAttributeName` defaults to `_csrf`.
|
|
If you configured the following only for the purpose of updating to 6.0, you can now remove it:
|
|
|
|
requestHandler.setCsrfRequestAttributeName("_csrf");
|
|
|
|
== Protect against CSRF BREACH
|
|
|
|
In Spring Security 5.8, the default `CsrfTokenRequestHandler` for making the `CsrfToken` available to the application is `CsrfTokenRequestAttributeHandler`.
|
|
`XorCsrfTokenRequestAttributeHandler` was added to allow opting into CSRF BREACH support.
|
|
|
|
In Spring Security 6, `XorCsrfTokenRequestAttributeHandler` is the default `CsrfTokenRequestHandler` for making the `CsrfToken` available.
|
|
If you configured the `XorCsrfTokenRequestAttributeHandler` only for the purpose of updating to 6.0, you can remove it completely.
|
|
|
|
[NOTE]
|
|
====
|
|
If you have set the `csrfRequestAttributeName` to `null` in order to opt out of deferred tokens, or if you have configured a `CsrfTokenRequestHandler` for any other reason, you can leave the configuration in place.
|
|
====
|
|
|
|
== CSRF BREACH with WebSocket support
|
|
|
|
In Spring Security 5.8, the default `ChannelInterceptor` for making the `CsrfToken` available with xref:servlet/integrations/websocket.adoc[WebSocket Security] is `CsrfChannelInterceptor`.
|
|
`XorCsrfChannelInterceptor` was added to allow opting into CSRF BREACH support.
|
|
|
|
In Spring Security 6, `XorCsrfChannelInterceptor` is the default `ChannelInterceptor` for making the `CsrfToken` available.
|
|
If you configured the `XorCsrfChannelInterceptor` only for the purpose of updating to 6.0, you can remove it completely.
