Vulnerabilities and Case Studies
Privilege Escalation via AWS Signer to Sign Code using Unauthorized ACM Certificate
AWS ACM has a missing security boundary that allows users with AWS Signer permissions — but without ACM permissions — to sign code using any ACM certificate within the same account. This bypasses critical security checks, enabling unauthorized code to be signed and potentially distributed as legitimate software. This can lead to significant security risks, including data breaches and system compromises.

Four risks of low-code/no-code in cloud security — and how to manage them
In today’s cloud-first world, organizations strive to enhance their security posture while staying agile. Low-code and no-code platforms have emerged as powerful tools that let users build applications and automate workflows with little to no programming expertise. These platforms are transforming cloud security by streamlining complex processes and allowing rapid deployment of security products. However, they also introduce potential risks that teams must carefully manage to maintain a strong security framework.
