CVE-2024-24752

Summary

CVE-2024-24752: Bref, a serverless PHP deployment tool for AWS Lambda, allows an attacker to fill the Lambda instance disk by manipulating MultiPart requests. When Bref converts a MultiPart event to a PSR7 object, each file is temporarily saved in `/tmp` without deletion upon request processing completion. This vulnerability, which mimics PHP's behavior but lacks proper cleanup, can be exploited to consume valuable disk space and potentially impact Lambda performance. The issue has been resolved in version 2.1.13.
