CVE-2024-3656
Keycloak's admin API allows low privilege users to use administrative functions
Impact

This issue presents a significant security risk as it allows unauthorized users to perform actions reserved for administrators, potentially leading to data breaches or system compromise. **Acknowledgements:** Special thanks to Maurizio Agazzini for reporting this issue and helping us improve our project.
