What is CVE-2025-56800?
CVE-2025-56800 is a medium-severity authentication bypass vulnerability in n/a, published on 21 Oct 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
