Error when installing app from My Company Applications – missing security_attribute SAC_1818458457

[jordimsant]

Hi everyone,

I tried to install an application we had stored under My Company Applications in our personal instance (PDI) running the Zurich release, and I encountered the following error:

sys_security_acl_bc91c2a5f334621048dff31278653048 / Could not find a record in sys_security_attribute for column security_attribute referenced in this update

When checking this ACL record, I noticed that it references a security_attribute named "SAC_1818458457" with sys_id = bc91c2a5f334621048dff3d264780663.
This security_attribute was created by a user called "@@snc_write_audit@@" on 12/05/2025 (dd/mm/yyyy), which is not a user from my instance.

After searching for more information, I found KB2046494, which explains that such records might have been created as part of a temporary security patch to mitigate a vulnerability. From what I understood in that KB, the issue was already resolved around July.

What I’d like to understand is:

1. What exactly is the purpose of this security_attribute?

2. Why is it missing in new instances (it’s not present in my newly created PDI)?

3. Since it doesn’t exist in new instances, can I safely remove this security_attribute from my app’s ACLs without causing any issues?

4. If I shouldn’t remove it, how can I prevent this installation error from occurring?

Thanks in advance for any clarification!

My pointers:

Purpose: The security_attribute was a temporary access control element added by ServiceNow to address a security vulnerability in May 2025.​

-> Missing in New Instances: New Zurich PDIs do not contain these attributes, as they were deprecated and removed after permanent fixes.​

-> Safe to Remove: Yes, you can safely remove the reference to the missing security_attribute from ACLs; it is no longer needed and only causes errors.​

-> How to Prevent Error: Delete the security_attribute references from ACLs before exporting or installing the app on new instances.- The security_attribute was a temporary security control added by ServiceNow to mitigate a vulnerability in May 2025.​

-> It is missing in new Zurich instances because it was removed after ServiceNow applied a permanent fix.​

-> You can safely remove references to this security_attribute from your ACLs; it is not needed in updated environments.​

-> To avoid installation errors, clear the security_attribute field from ACLs before installing or exporting your app.​
