0 CVE-2026-111252 is a denial of service vulnerability in OpenNMS Meridian and Horizon XML parsing. It arises from improper restriction of recursive entity references in DTDs, allowing an authenticated user with provisioning access to cause memory exhaustion by supplying crafted XML documents with large or deeply nested entity expansions. The vulnerability affects multiple versions prior to Meridian 2024.3.14, 2025.0.11, 2026.0.1 and Horizon 36.0.5. The vendor has released fixes that cap entity expansions and reject DOCTYPE declarations in requisition and foreign-source XML.
