Sep 1, 2026A vulnerability relating to incorrect access control in OpenNebula by OpenNebula Systems, affecting all versions prior to 7.4.CVE-2026-84165 · Other software · OpenNebula Systems · reported by cve-coordination@incibe.esHigh 8.7
A vulnerability relating to incorrect access control in OpenNebula by OpenNebula Systems, affecting all versions prior to 7.4. This vulnerability could allow an authenticated user with basic permissions to execute commands on virtual machines belonging to other users via the `one.vm.exec` function, without proper verification of access permissions. To exploit the vulnerability, it is only necessary to know the virtual machine’s identifier and for qemu-agent to be enabled on that machine. Exploitation could allow commands to be executed and compromise the confidentiality, integrity and availability of the affected virtual machines.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
