Improper Restriction of XML External Entity Reference
Spring Data Commons, versions 1.13 prior to 1.13.12 and 2.0 prior to 2.0.7, used in combination with XMLBeam 1.4.14 or earlier versions, contains a property binder vulnerability caused by improper restriction of XML external entity references as underlying library XMLBeam does not restrict external reference expansion. An unauthenticated remote malicious user can supply specially crafted request parameters against Spring Data's projection-based request payload binding to access arbitrary files on the system.
CWE-611 - Improper Restriction of XML External Entity Reference
Listed 4th in the 'OWASP Top Ten', XML External Entities (XXE) vulnerability allows attackers to provide an XML input that contains an external entity. When the XML is parsed, it can cause data extraction and manipulation, execution of commands, denial-of-service attacks, and server-side request forgery.
