CVE-2023-36813Public exploitNetwork attack vector

Authenticated database disclosure via unvalidated column names

Published Jul 5, 2023 · Updated Feb 13, 2025

SQL injection in Kanboard before 1.2.31 allows remote authenticated users to disclose database contents through crafted form fields. ProjectEditController and other update paths pass user-controlled form keys to PicoDB as SQL column identifiers without validating their syntax. Any signed-in user who can create a personal project can inject expressions that expose session tokens or password hashes, enabling account takeover.
