CVE-2026-88794: Sparx Systems Enterprise Architect XXE injection in XSLT Debugger

CVE-2026-88794 · Severity: info · Published 2026-10-15

Sparx Systems Enterprise Architect is a software modeling and design tool used by enterprises to create technical diagrams and system architecture documentation. The XSLT Debugger feature fails to restrict XML external entity processing, allowing an attacker to craft a malicious XML file that, when opened by a user, reads sensitive files from the victim's computer. This can lead to exposure of configuration files, source code, credentials, or other confidential data stored on the affected system.

Vendors: Sparx Systems.

Technical details

The vulnerability is an XML External Entity (XXE) injection flaw in the XSLT Debugger component. When a user loads a crafted XML file containing a DOCTYPE with an external DTD reference, the XML parser processes external entities without proper restrictions, enabling arbitrary file read on the local filesystem. The attack requires user interaction (opening a malicious XML file) and is triggered via the Debugger feature; no network access to the target is required.
