Overview

CVE-2026-63416 is a low-severity vulnerability. It was published on September 21, 2026 and has a CVSS 3.1 base score of 3.7 (LOW).

This vulnerability has a CVSS 3.1 base score of 3.7, rated LOW. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

draw.io is a configurable diagramming and whiteboarding application. Prior to version 30.2.7, src/main/java/com/mxgraph/online/ExportProxyServlet.java uses request.getPathInfo() to build a proxyPath and appends it directly to EXPORT_URL without rejecting dot segments or confirming that the normalized destination remains under the configured export path. An unauthenticated request containing traversal segments can therefore address unintended routes on the internal export server, and the servlet forwards all request headers and the request body to that destination, allowing arbitrary header injection. Depending on the export service configuration, exploitation can expose administration, debugging, health, or configuration endpoints and can permit unintended internal actions. This issue is fixed in version 30.2.7.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
