Form.io, a popular platform for serverless applications, has been found to contain a flaw that allows for path traversal. Specifically, versions 3.5.6 and lower, as well as 4.0.0-rc.1 through 4.4.2, are vulnerable. Attackers can send specially crafted requests, enabling them to access protected endpoints without authentication.

Why this Matters to Server Admins

For system administrators and hosting providers, this vulnerability highlights critical issues surrounding server security, particularly in environments where web applications handle sensitive data. An exploited vulnerability can lead to data breaches, compromising user information and organizational trust.

The exploitation could also potentially open avenues for further attacks, such as brute-force attacks, making it crucial for hosting providers to act swiftly.

Mitigation Steps
