Grails is a framework used to build web applications with the Groovy programming language. A specially crafted web request can lead to a JVM crash or denial of service. Any Grails framework application using Grails data binding is vulnerable. This issue has been patched in version 3.3.17, 4.1.3, 5.3.4, 6.1.0.
In grails-databinding in Grails before 3.3.15, 4.x before 4.1.1, 5.x before 5.1.9, and 5.2.x before 5.2.1 (at least when certain Java 8 configurations are used), data binding allows a remote attacker to execute code by gaining access to the class loader.
Grails uses cleartext HTTP to resolve the SDKMan notification service.
Grails Fields plugin version 2.2.7 contains a Cross Site Scripting (XSS) vulnerability in using the display tag that can result in XSS. This vulnerability has been fixed in version 2.2.8.
Cross-site request forgery (CSRF) vulnerability in Grails console (aka Grails Debug Console and Grails Web Console) allows remote attackers to hijack the authentication of users for requests that execute arbitrary Groovy code via unspecified vectors.
The default configuration of the Resources plugin does not properly restrict access to files in the WEB-INF directory, which allows remote attackers to obtain sensitive information via a direct request. NOTE: this identifier has been SPLIT due to different researchers and different vulnerability types. See CVE-2014-2857 for the META-INF variant and CVE-2014-2858 for the directory traversal.
