What is CVE-2026-92921?
The admin3 product by cjbi is vulnerable due to its reliance on single-round MD5 hashing for storing user account passwords. This method utilizes only the username as the salt and lacks a proper key derivation function, making it susceptible to offline dictionary and brute-force attacks. Attackers with access to the database can retrieve plaintext passwords with minimal computational effort, posing a significant risk to user security and privacy.
