The summary by CVE is:

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.

The advisory is shared at shinycolumn.notion.site. The identification of this vulnerability is CVE-2025-56800 since 08/17/2025. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 11/18/2025).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
