CVE-2025-0473 | Incomplete Cleanup vulnerability in PMB platform

Vulnerability in the PMB platform that allows an attacker to persist temporary files on the server, affecting versions 4.0.10 and above. This vulnerability exists in the file upload functionality on the ‘/pmb/authorities/import/iimport_authorities’ endpoint. When a file is uploaded via this resource, the server will create a temporary file that will be deleted after the client sends a POST request to ‘/pmb/authorities/import/iimport_authorities’. This workflow is automated by the web client, however an attacker can trap and launch the second POST request to prevent the temporary file from being deleted.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.

Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
