NVD Description

IBM InfoSphere Information Server 11.7.0.0 through 11.7.1.6 An XML External Entity (XXE) vulnerability in IBM InfoSphere Information Server could allow attackers to retrieve sensitive information from the server.

Deeper analysisAI

CVE-2026-1567 is an XML External Entity (XXE) vulnerability, classified under CWE-611, affecting IBM InfoSphere Information Server versions 11.7.0.0 through 11.7.1.6. The flaw resides in the software's handling of XML inputs, enabling attackers to retrieve sensitive information from the server. It carries a CVSS v3.1 base score of 7.1, reflecting network accessibility, low attack complexity, and impacts on confidentiality and availability.

A low-privileged user (PR:L) can exploit this vulnerability remotely over the network (AV:N) with low complexity and no user interaction required (UI:N). Successful exploitation allows limited disclosure of sensitive information (C:L) and high disruption to availability (A:H), while integrity remains unaffected (I:N) in an unchanged scope (S:U).

IBM's security advisory at https://www.ibm.com/support/pages/node/7259630 provides details on mitigation, including available patches for the affected versions. Security practitioners should consult this reference for upgrade instructions and workarounds.
