This critical-severity CVE scores 9.1 under NVD CVSS v3. EPSS exploit probability: 0.3%, top 74% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Schule is open-source school management system software. The application relies on client-side JavaScript (index.js) to redirect users to different panels based on their role. Prior to version 1.0.1, this implementation poses a serious security risk because it assumes that the value of data.role is trustworthy on the client side. Attackers can manipulate JavaScript in the browser (e.g., via browser dev tools or intercepting API responses) and set data.role to any arbitrary value (e.g., "admin"), gaining unauthorized access to restricted areas of the application.
