CVE-2025-56800

Exp

Reolink desktop application 8.18.12 contains a vulnerability in its local authentication mechanism. The application implements lock screen password logic entirely on the client side using JavaScript within an Electron resource file. Because the password is stored and returned via a modifiable JavaScript property(a.settingsManager.lockScreenPassword), an attacker can patch the return value to bypass authentication. NOTE: this is disputed by the Supplier because the lock-screen bypass would only occur if the local user modified his own instance of the application.

Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
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:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:N)
Service keeps running; no real outage angle.
