The vulnerability allows a remote attacker to bypass authorization checks.

The vulnerability exists due to missing authorization checks for source-asset deletion during asset file replacement operations. A remote user can replace files in one volume and delete assets in another volume where they do not have delete permission.


3) Improper Authorization (CVE-ID: N/A)

CWE-ID: CWE-285 - Improper Authorization

The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper control of dynamically assigned object attributes in "id" within newAttributes. A remote user can predict or enumerate element IDs to overwrite any other element.


5) Improper access control (CVE-ID: N/A)

CWE-ID: CWE-284 - Improper Access Control

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
