get method of ModuleClassLoaderLocator requires createClassLoader permission ---------------------------------------------------------------------------- Key: WFLY-8760 URL: https://issues.jboss.org/browse/WFLY-8760 Project: WildFly Issue Type: Bug Components: Security Reporter: Ondrej Lukas Assignee: Lin Gao Priority: Critical There is missing doPriviliged block in ModuleClassLoaderLocator. Fix of WFLY-7412 for ModuleClassLoaderLocator introduces new CombinedClassLoader innner class which extends SecureClassLoader. Initialization of this class needs to createClassLoader RuntimePermission. That means: * All deployment which uses API which internally uses ModuleClassLoaderLocator needs createClassLoader RuntimePermission (which is new in EAP 7.1, the same deployments in EAP 7.0 does not need this permission) ** i.e. getMappingContext(String mappingType) in org.jboss.security.plugins.mapping.JBossMappingManager works internally with ModuleClassLoaderLocator. * setting createClassLoader RuntimePermission for deployment can be dangerous and it should probably use own permission
