Technical details

A second-order (time-based blind) SQL injection vulnerability exists in Focalboard version 8.0. The application fails to sanitize category IDs before they are stored in the database and subsequently used in dynamic SQL statements within the category reorder API. An authenticated attacker can submit a malicious SQL payload in the category ID field; when the reorder API later processes this stored value, the payload is executed. This allows for the exfiltration of sensitive data, such as user password hashes. As the standalone product is end-of-life, no fix is available.
