Grails Spring Security Core plugin is vulnerable to privilege escalation. The vulnerability allows an attacker access to one endpoint (i.e. the targeted endpoint) using the authorization requirements of a different endpoint (i.e. the donor endpoint). In some Grails framework applications, access to the targeted endpoint will be granted based on meeting the authorization requirements of the donor endpoint, which can result in a privilege escalation attack. This vulnerability has been patched in grails-spring-security-core versions 3.3.2, 4.0.5 and 5.1.1. Impacted Applications: Grails Spring Security Core plugin versions: 1.x 2.x >=3.0.0 =4.0.0 =5.0.0 Read More
