CVE-2026-63239 is a hard-coded credential vulnerability in Koollab LMS 5.3.2 involving embedded AWS IAM credentials. The exposed credentials permit access to shared multi-tenant Amazon S3 buckets and Amazon SQS queues used by the application. Because the credentials are hard-coded in the application context rather than securely provisioned and isolated per tenant, an attacker who obtains or abuses them can interact directly with backend cloud resources outside normal application authorization controls. This can expose tenant data stored in object storage and allow unauthorized interaction with queue-backed workflows.
