Metinfo: Improper Restriction of XML External Entity Reference

Published Updated By the CyberSecBulletin desk

CVE-2025-63551 is a high-severity improper restriction of XML external entity reference vulnerability in Metinfo, with a CVSS 3.1 base score of 7.5 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 8.1 as the first without the flaw, so updating Metinfo to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.51% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Metinfo to 8.1 or a later version.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

A Server-Side Request Forgery (SSRF) vulnerability, achievable through an XML External Entity (XXE) injection, exists in MetInfo Content Management System (CMS) thru 8.1. This flaw stems from a defect in the XML parsing logic, which allows an attacker to construct a malicious XML entity that forces the server to initiate an HTTP request to an arbitrary internal or external network address. Successful exploitation could lead to internal network reconnaissance, port scanning, or the retrieval of sensitive information. The vulnerability may be present in the backend API called by or associated with the path `/admin/#/webset/?head_tab_active=0`, where user-provided XML data is processed.

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.
