What is CVE-2025-8904?

A vulnerability in Amazon EMR's Secret Agent allows the creation of an insecure keytab file containing Kerberos credentials, stored in the /tmp/ directory. This poses a risk as users with access to this directory could potentially decrypt the stored keys, leading to unauthorized privilege escalation if they possess an additional account. It is crucial for users to upgrade to Amazon EMR version 7.5 or higher. For those operating versions between 6.10 and 7.4, it is recommended to utilize the bootstrap script and RPM files provided in the security fix.
