Description
The component accepts XML input through the publisher without disabling external entity resolution. This allows malicious actors to submit a crafted XML payload that exploits the unescaped external entity references.
By leveraging this vulnerability, a malicious actor can read confidential files from the product's file system or access limited HTTP resources reachable via HTTP GET requests to the vulnerable product.
