Yes. org.mapfish.print:print-lib (Maven): upgrade to 3.24 or later; org.mapfish.print:print-servlet (Maven): upgrade to 3.24 or later; org.mapfish.print:print-standalone (Maven): upgrade to 3.24 or later. Junglewise finds every place you run it, drafts the upgrade and applies it once you approve.
Am I affected by CVE-2020-15231?
Check whether you run org.mapfish.print:print-lib (Maven), org.mapfish.print:print-servlet (Maven) or org.mapfish.print:print-standalone (Maven) 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.
