What is CVE-2025-56802?

The Reolink desktop application contains a vulnerability due to the use of a hard-coded and predictable AES encryption key for encrypting user configuration files. This flaw allows attackers with local access to the system to potentially decrypt sensitive application data stored in the %APPDATA% directory. Although the vendor asserts that the encryption key is generated randomly during installation, the risk remains significant as predictable encryption compromises the integrity and security of user data.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
