Security issue - WEB API executing a PATCH

(0) ShareShare
ReportReport
Posted on by rthompson 1,532

Hi,

I have a WEB API that I am using a "PATCH".  The API is working correctly.  My problem that I am having is that I am getting a field permission error message.

The field that is throwing the error message is not the field that is getting updated by the user.  The user has "Read" only permission on the field.  

My question is why is the user having a permission issue.

var entity: any = {};
entity["new_issetupcompleted"] = isSetupCompleted;
let stringUrl = UrlQueryString.postTemplateUrl(StandardUtilityFunction.FormatGuid(templateId));

Crm.CrmPatchSingle(globalContext.getClientUrl()   stringUrl, entity, (data, textStatus, xhr) => {
}

I have the same question (0)

    Hello,

    Do you have any plugin/realtime workflow that is get triggered on update of new_issetupcompleted field by a chance that tries to update new_technicianassignedid field?

    Hi,

    Yes,  I do have a plugin that is doing the following. 

    if (templateEntity.Contains("new_technicianassignerid"))
{
    technicianAssignerLookup = (EntityReference)templateEntity.Attributes["new_technicianassignerid"];
}

    So even if the logic is never calling the above code the plugin checks all fields for security permission.  Is that correct?

    Does your plugin update the field? I see only assigning of the value of the field.

    No.  I even removed the code and still get the same permission error

    I don't believe in miracles - there should be the reason for it. Do you have anything meaningful in the full log part of which you posted in initial message?

    Hi,

    You said that you removed the code, any chances that your plugin's Pre or Post entity contains that field and somewhere else you use that entity object to make an update?

    I told you this because i've seen It happen:)

    Hope It Helps.

    Hi,

    I check and the field does not exist.   Question,  I have notice that when I do a post the entire entity data is being display in the API.  I thought the the only thing I should be see is the one field that I am updating.  Would that have something to do with it?

    Hi Andrew,

    After spending sometime with the code.  The plugin was using the postImageEntity to update the record rather then the actual entity.

    Thanks for your help!
