WSO2 Enterprise Integrator: Improper Restriction of XML External Entity Reference

Published Updated By the CyberSecBulletin desk

CVE-2025-10713 is a critical-severity improper restriction of XML external entity reference vulnerability in WSO2 Enterprise Integrator from WSO2, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 6.6.0.223 as the first without the flaw, so updating WSO2 Enterprise Integrator to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.46% chance of exploitation within 30 days, which is low compared with other CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update WSO2 Enterprise Integrator to 6.6.0.223 or a later version.
  2. Update WSO2 API Control Plane to 4.5.0.27 or a later version.
  3. Update WSO2 Universal Gateway to 4.5.0.25 or a later version.
  4. Read the advisory on security.docs.wso2.com for workarounds and exact fixed builds.
  5. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

An XML External Entity (XXE) vulnerability exists in multiple WSO2 products due to improper configuration of the XML parser. The application parses user-supplied XML without applying sufficient restrictions, allowing resolution of external entities. A successful attack could enable a remote, unauthenticated attacker to read sensitive files from the server's filesystem or perform denial-of-service (DoS) attacks that render affected services unavailable.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Improper Restriction of XML External Entity Reference

The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.

How developers prevent this class of flaw

  • Many XML parsers and validators can be configured to disable external entity expansion.
