Revoke Access Token check removed from OAuth Client Registration
Resolved in Pega Version 8.5.2
When client credentials were implemented, the OAuth 2.0 Client Registration form was designed such that once the instance was created and a token issued, the access tokens were deleted on save. Process changes now indicate that it should be possible to save the form because it may only have History Description/Usage changes made to it and Revoke Token and Regenerate Secret buttons are already available. To address this, the Revoke Access Token check has been removed from the validate activity of Client Registration.

Resolved 403 error for refresh of incognito window with CSRF
Resolved in Pega Version 8.5.2
Opening the simpleurl in a fresh incognito window opened the work object in a standard thread, but on refresh of the window a 403 error appeared and the screen went blank. This was a missed use case for the recently-added CSRF validation for non-ajax get requests which are redirected post requests. The CSRF token was being validated if pzPostData was in the request, but once the original request was complete the request map was cleared and the pzCtkn value in the request map was empty, resulting in the 403 error. To resolve this, the system will skip CSRF validation for a refresh scenario where the post data request map is empty after the original request, and validation has been added for the blank pyActivity in the request.

Updated handling for MT query of pr_data_admin table
Resolved in Pega Version 8.5.2
When using a multi-tenant environment with Oracle, as the number of users in the environment increased, the number of queries of the pr_data_admin table "WHERE pyEnableAuthService" increased exponentially and causes system slowness. This was traced to missed handling for the @ character in the authentication service cache while requesting, and has been resolved by updating authservicecache.java.

Property check handling updated for Ajax requestor
Resolved in Pega Version 8.5.2
SECU0001 alerts were seen when submitting a case in the interaction portal. Logging indicated the errors were related to the 'pxRequestor.pyLatitude' and 'pxRequestor.pyLongitude' properties which are included in an Ajax request when they exist in the DOM and the 'pyGeolocationTrackingIsEnabled' when rule is true. The error was traced to a condition where a new thread request results in an unexpected property check that encounters a clipboard which doesn't have any pages created for that thread. To resolve this, the 'pxRequestor.pyLatitude' and 'pxRequestor.pyLongitude' properties have been added to an allow list to handle the unexpected properties check.

Hash comparisons adjusted for upgraded sites
Resolved in Pega Version 8.5.2
Existing Pega Diagnostic Cloud SSO URLs were not working after upgrade. This was traced to the previous tenant hash (or AG hash) having padding characters like ‘(’ which are no longer used in higher versions. This caused the tenant hash comparison during the SAML login flow to fail. To resolve this, the system will not compare an incoming tenant hash (in relay state) with a current platform tenant hash, but instead will rely on the “/!” pattern to identify the tenant hash in the relay state.

Enhancements for upgrading in multi-tenant environment
Resolved in Pega Version 8.5.2
Some muti-tenant installations use the same applications or rule instances with the same pzInsKeys for different tenants. This can cause upgrades to time out due to the system fetching all pzInsKeys (which will have duplicates) and working with them in a default batch size of 500 each over 4 threads. This led to the same keys potentially being allocated and processed in different threads, resulting in duplicate processing and timeouts. This has been resolved by updating the select query to fetch the tentantid and pzInskeys in the MT system to avoid duplicate work in multiple threads. In addition, running Generate Declarative indexes fetches the pzinskeys and generates indexes for each record, but before generating, the existing index for the record is deleted and then inserted. Because the delete query to generate the index was not tenant aware, all of the records for the key were deleted for the tenants for that key, but the new index was created only in one tenant. This has been resolved by enhancing the DELETE query to be tenant aware, which will avoid deleting the indexes for all the tenants given an index key.
