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.
