PHP Input Validation Bypass Vulnerability

PHP is prone to a vulnerability because it fails to sufficiently sanitize user-supplied input. Exploiting this issue can allow attackers to provide unexpected input and possibly bypass input-validation protection mechanisms. This can aid in further attacks that may utilize crafted user-supplied input.

Mitigation:

Input validation should be used to ensure that user-supplied data is properly sanitized.
