Corrected report definition save-as-image option
Resolved in Pega Version 8.5.6
Attempting to save a report definition as an image resulted in an access denied error stating "Browser fingerprint validation failed : A request was received with an invalid or missing browser fingerprint. The request was denied", and the user session was closed. The security SECU0017 alert is generated when a request is sent to a Pega application and the browser fingerprint is either missing or does not match the expected value. The system tries to check the type of request for every requestor ID and fetch the CSRF token, but in this case it was not matching with the token present on the requestor thread. This has been resolved by adding scripts to send the hidden input value needed.

OAuth token refreshed when revoked on source
Resolved in Pega Version 8.5.6
When an OAuth token was used to authorize the APIs in the system, revoking the token at the source, i.e. from the Service side, did not automatically refresh the token and a logoff/logon was required before a fresh token was generated. This has been resolved by adding an update to explicitly purge revoked tokens.

Removed duplicate clipboard page creation
Resolved in Pega Version 8.5.6
An out of memory exception occurred due to the pyInstanceInfoForUpdate clipboard page having 6.5M Embed-InstanceInfo entries. This was traced to the ClientUpdateRequestHandler.getInstanceInfoPage method continuously appending to the ClipboardProperty instanceInfoPage. This has been resolved by removing the extra creation of instance pages within the loop.

OIDC authentication service token reload updated
Resolved in Pega Version 8.5.6
The exception “PRSecurityException: Invalid State Parameter received" was generated along with "Unable to execute OIDC flow : Caught exception while parsing the id token”. The issue was identified in the Keystore cache refresh strategy for the 'reload once per interaction' option. While the Refresh interval was one minute for reload once per interaction, if there was a login request/keystore request in that one minute then the refresh interval was pushed to one minute again from that timestamp. The system was also maintaining the cache refresh interval as one minute. That meant if there were continuous requests, then the refresh interval was pushed to one minute for each request. As a result, the Refresh interval was repeatedly extended until the exception occurred. To resolve this, the Refresh token will happen if there are no requests for a period of one minute, and the cache refresh interval for "Reload once per iteration" has been removed completely.

Addressed intermittent Issues with OAuth2
