**Description**
The issue is related to a missing delay in the directory upload UI, which could allow an attacker to trick a user into granting permission via clickjacking. This could enable a remote attacker to conduct a clickjacking attack.
**Recommendations**
For Firefox versions prior to 131, update to version 131 or later to resolve the issue.
For Firefox ESR versions prior to 128.3, update to version 128.3 or later to resolve the issue.
