CVE-2024-31221 | Clients removed during unpairing process may regain access if Sunshine was not restarted

Exp

Sunshine is a self-hosted game stream host for Moonlight. Starting in version 0.10.0 and prior to version 0.23.0, after unpairing all devices in the web UI interface and then pairing only one device, all of the previously devices will be temporarily paired. Version 0.23.0 contains a patch for the issue. As a workaround, restarting Sunshine after unpairing all devices prevents the vulnerability.

Base score Version Severity Vector Exploitability Impact Score source
5.9 3.1 MEDIUM
CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:L/A:L Click to expand
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:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
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:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
