CVE-2026-63229 is a critical pre-authentication blind SQL injection vulnerability affecting Three Learning Koollab LMS version 5.3.2. The flaw is present in the SSO OAuth endpoint, where insufficient neutralization of attacker-controlled input in SQL queries allows unauthenticated remote attackers to trigger a time-based SQL oracle. By issuing crafted requests and inferring database responses from timing differences, an attacker can extract sensitive information from the backend database without needing valid credentials or user interaction. Exposed data may include personally identifiable information, credential material, and valid JWT tokens, creating a path to subsequent unauthorized access and account takeover.
