CVE-2024-28056

30
FAUCET Score

CVE-2024-28056 is a critical vulnerability in Amazon AWS Amplify CLI versions prior to 12.10.1, affecting the configuration of IAM role trust policies. When an authorized user removes the Authentication component from an Amplify project, a misconfiguration leaves the sts:AssumeRoleWithWebIdentity action unconditionally available, potentially allowing unauthorized access to AWS resources. This vulnerability has a CVSS score of 9.8 (CRITICAL) due to its network attack vector, low complexity, and high impact on confidentiality, integrity, and availability. While there is no evidence of active exploitation, public exploit code, or significant community discussion, the potential for unauthorized role assumption makes it a severe risk.
