Certificate assignment fails with "Permission denied" when logged in as customer (works as admin)

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE

Plesk Obsidian 18.0.80.7, AlmaLinux 9.4 x86_64

PROBLEM DESCRIPTION

When assigning an uploaded or self-signed SSL/TLS certificate to a domain's hosting via Hosting & DNS > Hosting > Certificate, Plesk returns "Permission denied" and the certificate is not saved/assigned.

This only occurs when logged in as the customer (subscription owner). Performing the same steps while logged in as admin works correctly with no error.

STEPS TO REPRODUCE

1. Create a customer account:

plesk bin customer --create example.com -name "example.com" -passwd "ComplexPassword@123"

1. Create a subscription:

plesk bin subscription --create example.com -owner example.com -service-plan "Plan 1" -ip 1.2.3.4 -login ftp_example -passwd "ComplexPassword@123"

1. Log in to Plesk as example.com.
2. Go to Dashboard > SSL/TLS Certificates > Manage > Add SSL/TLS Certificate, and either generate a self-signed certificate or upload a certificate.
3. Go to Hosting & DNS > Hosting > Certificate, select the self-signed/uploaded certificate, and click Save.

ACTUAL RESULT

Error: Permission denied. (Only reproducible as customer; admin can perform the same action successfully.)

EXPECTED RESULT

The selected certificate should be saved and assigned to the domain's hosting without error.
