What it is: CVE-2023-4861 is a high-severity vulnerability in Unknown File Manager Pro, published on 16 Oct 2023. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-4861 exists.

Affected product: Unknown File Manager Pro. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
