Critical CVSS 9.1

CVE-2026-63230

A pre-authentication error-based SQL injection vulnerability in Koollab LMS allowed an unauthenticated attacker to read sensitive database contents, including personally identifiable information, credentials, and valid JWT tokens that may enable account takeover, via the SCORM report endpoint.

What this means

Exposure
Exploitable remotely over the network, without authentication and with no action from the victim.
Impact
An attacker can read sensitive data and modify or destroy data.
Weakness
Unescaped input is placed into an SQL query, letting the attacker read or alter the database (SQL injection).
Likelihood
Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.

What to doPatch without waiting for the next scheduled cycle. Start with the instances exposed to the internet.
