Temporary suspension of access to Leonardo, G100, Pitagora, EFGW login nodes  (https://www.hpc.cineca.it/newsletter/temporary-suspension-of-access-to-leonardo-g100-pitagora-efgw-login-nodes/) 

22 July 2026 

Dear Users, 

Due to a recently identified security vulnerability, we need to temporarily suspend access to the login nodes of all clusters while analysis and mitigation activities are carried out. 

As a precautionary measure, access to the login nodes will be disabled effective immediately. Running jobs will continue to be monitored, and we will provide further information if any additional actions become necessary. 

Our teams are actively working to address the issue and restore normal operations as quickly as possible while ensuring the security and integrity of the HPC infrastructure. 

We will keep you informed of any significant updates and will notify you as soon as access is restored. 

Best regards, 

HPC User Support - CINECA
