Check whether you run zendframework/zendframework (Packagist) or zendframework/zendframework1 (Packagist) at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.
