Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.
