Zod denial of service vulnerability during email validation

Impact

API servers running express-zod-api having:

are vulnerable to a DoS attack due to:

Patches

The patched version of zod fixing the vulnerability is 3.22.3.

However, it's highly recommended to upgrade express-zod-api to at least version 10.0.0, which does not depend on zod strictly and directly, but requires its installation as a peer dependency instead, enabling you to install the patched zod version yourself.

Workarounds

When it's not possible to upgrade your dependencies, consider the following replacement in your implementation:

- z.string().email()
+ z.string().regex(
+   /^(?!\.)(?!.*\.\.)([A-Z0-9_+-\.]*)[A-Z0-9_+-]@([A-Z0-9][A-Z0-9\-]*\.)+[A-Z]{2,}$/i
+ )

This regular expression is taken from the suggested patch of zod.
