CVE-2026-24664 is a medium severity username enumeration vulnerability in the Open eClass platform (formerly GUnet eClass) versions prior to 4.2. It allows unauthenticated attackers to identify valid usernames by analyzing observable differences in login response behavior. This vulnerability does not impact confidentiality beyond username disclosure, nor does it affect integrity or availability. Exploitation requires no authentication or user interaction and can be performed remotely over the network. The issue has been patched in version 4.2. European organizations using affected versions should update promptly to prevent potential reconnaissance activities that could facilitate further attacks. Countries with significant adoption of Open eClass in educational institutions are most at risk. Mitigation involves upgrading to version 4.
