Overview
vrana/adminer is a Database management in a single file.
Affected versions of this package are vulnerable to Insecure Randomness in the CSRF token generation process. An attacker can recover the session secret and forge valid tokens by observing a single CSRF token, which may be obtained through network sniffing, log files, Referrer headers, or XSS. This allows execution of unauthorized actions, including arbitrary SQL queries, by exploiting the predictable token structure, low-entropy session token, and loose comparison in token verification.
