CSRF warnings

[Lipscomb, Gary]

Further investigation
https://wiki.shibboleth.net/confluence/display/DEV/Anti-CSRF+FlowExecutionListener+Implementation 

It is recommended the following view-states are not excluded.
LocalStorageRead	client-storage-read.vm, read.vm
LocalStorageWrite	local-storage-write.vm, write.vm

Did these 2 views get missed from here

Hi,

IdP v4.0
RHEL 8
Tomcat 9

We have just moved to IdP v4.0, a new install, and have idp.csrf.enable = true and seeing these errors intermittently in the logs


2021-03-26 09:56:50,190 - redactedIP-1 - WARN [net.shibboleth.idp.ui.csrf.impl.CSRFTokenFlowExecutionListener:183] - CSRF token is required but was not found in the request; for view-state 'LogoutCompleteView' and event 'proceed'.
2021-03-26 10:28:21,081 - redactedIP-2  - WARN [net.shibboleth.idp.ui.csrf.impl.CSRFTokenFlowExecutionListener:183] - CSRF token is required but was not found in the request; for view-state 'LogoutCompleteView' and event 'proceed'.

We have customised the idp.home/views/logout.vm, have I missed re-adding a csrf setting, though I couldn’t see anything in the vanilla release logout.vm

2021-03-26 10:47:29,498 - RedactedIP-3 - WARN [net.shibboleth.idp.ui.csrf.impl.CSRFTokenFlowExecutionListener:193] - CSRF token in the request did not match that stored in the view-scope; for view-state 'LocalStorageRead' and event 'proceed'.
2021-03-26 10:47:29,499 - RedactedIP-3 - WARN [org.opensaml.profile.action.impl.LogEvent:101] - A non-proceed event occurred while processing the request: InvalidCSRFToken
2021-03-26 10:51:40,807 - RedactedIP-4 - WARN [net.shibboleth.idp.ui.csrf.impl.CSRFTokenFlowExecutionListener:193] - CSRF token in the request did not match that stored in the view-scope; for view-state 'LocalStorageRead' and event 'proceed'.

I think this may relate to attribute-release and we have added #parse("csrf/csrf.vm") to that view

Is there anything else I may have missed.

Regards

Gary
