A.8.26 Application security requirements partial match
blocks

A.8.26 only requires that security requirements (including resilience against attacks such as injections) be identified and specified during development or acquisition; it does not itself enforce, implement or otherwise stop a guessable CAPTCHA from being exploitable.
