About Vmware Aria Operations
CVE-2026-22720 affects Vmware Aria Operations, a product from Vmware. Before acting, confirm where Vmware Aria Operations runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.
What the flaw is
In plain terms: VMware Aria Operations contains a stored cross-site scripting vulnerability. A malicious actor with privileges to create custom benchmarks may be able to inject script to perform administrative actions in VMware Aria Operations. To remediate CVE-2026-22720, apply the patches listed in the 'Fixed Version' column of the 'Response Matrix' of VMSA-2026-0001 https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/36947https:// .
The weakness class is Cross Site Scripting. Attacker supplied script runs in another user's browser inside the trusted site.
Based on its CVSS vector, the flaw can be reached over the network, needs some level of access, and relies on a user taking an action. Apply the vendor fix and confirm exposure on internet facing and business critical assets first.
