🦉 Regular Expression Denial of Service (ReDoS)

[bwappsec]

This major version upgrade from 4.x to 5.0.0 introduces a significant behavioral change in how validation errors are reported.

Breaking Change:
By default, request and response validation now stops after the first validation failure. [1] Previously, the validator would collect and report all errors, but now it will only report the first one it encounters. This change aligns with security best practices from the underlying AJV v8 validation library. [1]

Impact:
Error handling logic that is designed to parse or display an array of multiple validation errors (err.errors) will be affected. Code expecting multiple errors may now only receive a single error, which could break how your application processes and responds to invalid requests.

Recommendation:
Review and test your application's error handling middleware. Ensure that any code processing validation errors correctly handles the new behavior of receiving only a single error instead of an array of errors.
