U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Ivanti Sentry flaw to its Known Exploited Vulnerabilities catalog.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added Ivanti Sentry flaw, tracked as CVE-2026-10520 (CVSS score of 10.0), to its Known Exploited Vulnerabilities (KEV) catalog.

The vulnerability affects the secure mobile gateway used to protect communications between corporate systems and mobile devices. Although Ivanti initially reported no evidence of active attacks, researchers at Shadowserver found that many internet-exposed Sentry gateways had already been backdoored shortly after the security updates were released.

“We are observing a large amount of Ivanti Sentry CVE-2026-10520 exploitation attempts based on the public PoC today. We see 19 vulnerable instances in our own scans, with at least 2 backdoored (thanks to @NCA_KSA for the tip!). However, all remaining likely compromised too.” the Shadowserver Foundation posted on X. “While our detection is on the lowish side due to multiple Ivanti Sentry instances not reachable in our scans (blocklisted?), if you have not patched you are most likely compromised.
