CVE-2026-111252 Oct 15, 18:56 MEDIUM PATCH This Month

Memory exhaustion in OpenNMS Meridian and Horizon lets an authenticated user who holds provisioning privileges crash the monitoring server by supplying XML that declares internal entities designed to expand uncontrollably - either directly through a requisition or foreign-source import, or indirectly via a remote requisition URL that the server fetches and parses itself. The flaw is rated CVSS 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H), so a successful attack yields full availability loss with no confidentiality or integrity impact, and no public exploit code was identified at time of analysis (the issue is not listed in CISA KEV). This is a moderate-priority availability issue rather than a drop-everything emergency: the attacker must already hold a trusted provisioning account, and the vendor states that Meridian and Horizon are intended for private-network deployment rather than direct internet exposure.
