Before this fix, a user could start System Tasks or User Tasks that were not
exposed to this user via undocumented URLs.
The new functionality is:
"With URLs it is possible,
to start Human Services that are exposed to the logged-on user
to start Ajax Services.
Execution of other service types is rejected, unless
the request arrives on the Process Center and
the request was issued by Process Designer in a playback session and
the user that issued this request is a member of the tw_authors group and
the user is granted Read access to the process app.
If this behaviour conflicts with existing solutions, it is possible to disable
the new checks.
To do this, add
<server merge="mergeChildren">
<web-workflow-manager merge="mergeChildren">
<enforce-correct-service-type-for-execute-service-by-name>false</enforce-correct-service-type-for-execute-service-by-name>
