Failed to validate CSRF token for the URL: /sm9/service.do

Hi, I am seeing these errors in the sm log in SM Web client in Tomcat and am wondering if anyone knows what this means? Here is the full error:

 

ERROR ajp-bio-8012-exec-17 com.hp.ov.web.csrf.AntiCSRFFilter - Failed to validate CSRF token for the URL: /sm9/service.do

 

We have an issue where multiple people are having issues accessing SRC (Service Request Catalog) and I think this might be a reason why.

 

Thanks.
