CVE-2026-63229: Vulnerability in Three Learning Koollab LMS
CVE-2026-63229 is a critical pre-authentication blind SQL injection vulnerability in Three Learning's Koollab LMS version 5.3.2. It allows an unauthenticated attacker to exploit a time-based SQL oracle via the SSO OAuth endpoint to extract sensitive database information, including personally identifiable information, credentials, and valid JWT tokens that could enable account takeover.
AI Analysis
Technical Summary
This vulnerability in Koollab LMS (version 5.3.2) involves a blind SQL injection flaw in the SSO OAuth endpoint that does not require authentication. An attacker can leverage a time-based SQL oracle to read sensitive data from the backend database, such as PII, credentials, and JWT tokens. The CVSS 3.1 score is 9.1, indicating a critical severity with network attack vector, low attack complexity, no privileges or user interaction required, and high confidentiality and integrity impact. No official patch or remediation level has been provided yet, and no known exploits are reported in the wild.
Potential Impact
An attacker can remotely extract sensitive information from the Koollab LMS database without authentication. This includes personally identifiable information, user credentials, and valid JWT tokens, which may lead to account takeover and compromise of user data confidentiality and integrity. Availability is not impacted.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the SSO OAuth endpoint if possible and monitor for unusual activity related to authentication endpoints.
