CVE-2024-8010· NVD / CVE Program· CNA WSO2

XML External Entity Injection via Publisher in WSO2 API Manager Allows Reading Arbitrary Files

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.
