The affected Ebyte product uses a deprecated hashing algorithm in an authentication-related operation. Under conditions where an attacker can manipulate or predict the authentication exchange, the weak construction may reduce the assurance provided by the authentication mechanism and facilitate unauthorized access.

CVE-2026-76133 affects an Ebyte product that uses a deprecated hashing algorithm in an authentication-related operation. The weak cryptographic construction reduces the assurance of the authentication mechanism. Under conditions where an attacker can manipulate or predict the authentication exchange, unauthorized access may be facilitated. The vulnerability is classified as an authentication weakness tied to outdated cryptographic practices. It is tracked by NVD and has an associated CISA ICS advisory (icsa-26-237-06). The issue falls under the category of improper use of deprecated algorithms in security-critical operations. It is particularly relevant to OT/ICS environments given the CISA advisory context. The current risk level is rated High.
