Security Bulletin
Summary
IBM QRadar has an XML External Entity (XXE) injection vulnerability. This vulnerability is not exploitable in all configurations. All of the following conditions must be simultaneously true for a system to be at risk: (1) XML Property Autodetection must be actively enabled on at least one log source type. This is a non-default, manually configured setting that is not widely used across most deployments. (2) The event must be sent to the log source type with the XML Property Autodetection enabled. (3) The autodetection window must still be open. Property Autodetection is a transient feature which automatically disables itself after processing a threshold number of events or creating a set number of properties. On active systems, this window is likely to be brief. (4) An attacker must be able to deliver a specially crafted event to the QRadar system's syslog intake. This requires network-level access to the relevant port.
Vulnerability Details
CVEID: CVE-2026-10025
DESCRIPTION: IBM QRadar has an XML External Entity (XXE) injection vulnerability. The vulnerability resides in the parseXmlPayload() function within the event processing pipeline (q1labs_core.jar). When at least one log source type is configured to use XML-format property autodetection, the system processes XML-formatted syslog events sent to port 514 (UDP/TCP) without authentication.

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
