CVE-2026-96629: AdminNeo CSRF token vulnerability with session secret recovery

CVE-2026-96629 · Severity: medium · CVSS 6.8 · Published 2026-10-30

AdminNeo, a database administration interface, protects form submissions against cross-site request forgery (CSRF) attacks using tokens. However, the token design allows an attacker who observes a single token—through logs, network traffic, or other leakage—to instantly recover the session secret and forge valid tokens for any operation. An attacker can then perform arbitrary actions like dropping tables, creating backdoor accounts, or exfiltrating data under the victim's identity.

Technologies: AdminNeo, adminneo-org/adminneo (Packagist). Vendors: AdminNeo, Packagist.

Technical details

The vulnerability has three components: (1) the CSRF token format transmits both the XOR mask and masked value (`(rand XOR secret):rand`), allowing trivial secret recovery via `secret = masked_value XOR rand`; (2) the session token uses only ~20 bits of entropy (`rand(1, 1e6)`), making blind brute-force feasible; (3) token verification uses loose PHP comparison (`==` instead of `===`), enabling type juggling. An authenticated user needs only to view a single token to forge unlimited valid CSRF tokens, then execute SQL queries via the web interface with no further user interaction required.
