About Ivanti Standalone Sentry
CVE-2026-10523 affects Ivanti Standalone Sentry, a product from Ivanti. Before acting, confirm where Ivanti Standalone Sentry 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: An Authentication Bypass vulnerability (CWE-288) in Ivanti Sentry before the R10.5.2, R10.6.2 and R10.7.1 versions allows a remote unauthenticated attacker to create arbitrary administrative accounts and obtain full administrative access
The weakness class is Authentication Bypass via Alternate Path. A second route into the app skips the login check.
Based on its CVSS vector, the flaw can be reached over the network, needs some level of access, and needs no user interaction. Its EPSS score of 53.1 percent signals a high chance of exploitation, so patch it in your next emergency window.
