CVE-2022-47937 Critical 2023-05-15 No exploit published No public exploit Improper input validation in the Apache Sling Commons JSON bundle allows an attacker to trigger unexpected errors by supplying specially-crafted input. The org.apache.sling.commons.json bundle has been deprecated as of March 2017 and should not be used anymore. Consumers are encouraged to consider the Apache Sling Commons Johnzon OSGi bundle provided by the Apache Sling project, but may of course use other JSON libraries.
