CVE-2025-1862 is a high-severity vulnerability rated 7.2/10 on the CVSS scale. An arbitrary file upload vulnerability exists in multiple WSO2 products due to improper validation of user-supplied filenames in the BPEL uploader SOAP service endpoint. A malicious actor with administrative privileges can upload arbitrary files to a user-controlled location on the server. By leveraging this vulnerability, an attacker can upload a specially crafted payload and achieve remote code execution (RCE), potentially compromising the server and its data.. EPSS estimates a 0.50% chance of exploitation in the next 30 days.
