CVE-2025-56801Public exploit

Configuration disclosure via repeated AES-CFB initialization vector

Published Oct 21, 2025 · Updated Oct 21, 2025

Cryptographic weakness in Reolink Desktop Application 8.18.12 allows local users to decrypt encrypted configuration data. The fetchAesIv path invokes window.napiDecrypt.getAesIv(), which the researcher reports returns one repeated value for AES-CFB operations. Application-environment access is required; Reolink states that the value is instead generated randomly for each installation, so the finding is disputed.
