CVE-2026-63231 is a post-authentication SQL injection vulnerability affecting Koollab LMS version 5.3.2. The flaw is present in the face-to-face runs update endpoint, where insufficient neutralization of attacker-controlled input allows an authenticated user to trigger an error-based SQL oracle. By exploiting the injection condition, an attacker can query and extract data from the backend database beyond the intended application logic. Reported exploitation impact includes reading the entire application database and retrieving valid JWT tokens, which can then be used to compromise user accounts.
