Is CVE-2023-46805 being exploited?
Yes. CISA added CVE-2023-46805 to its Known Exploited Vulnerabilities catalog on . CISA only lists a CVE when it has reliable evidence of exploitation in the wild. CISA marks it as known to be used in ransomware campaigns.
FIRST's EPSS model puts the probability of exploitation activity in the next 30 days at 100.0% (scored October 25, 2026).

What to do
US federal civilian agencies must remediate by (12 days after listing) under BOD 22-01. Everyone else: that deadline is a sensible upper bound, not a target. Vendor guidance and the NVD record are linked under Source above.
CVE-2023-46805 is an authentication-bypass vulnerability affecting the web component of Ivanti Connect Secure (formerly Pulse Connect Secure) and Ivanti Policy Secure gateways. By itself it lets an unauthenticated attacker reach restricted endpoints that should require a valid session.
Ivanti and Mandiant disclosed in January 2024 that this flaw was being actively chained with a separate command-injection vulnerability, CVE-2024-21887, to achieve unauthenticated remote code execution on internet-facing VPN appliances — exploited in the wild as zero-days by a suspected nation-state actor before patches were available.
Why it mattered
Edge VPN appliances sit directly on the network perimeter with broad internal access by design, making them high-value targets. CISA issued an emergency directive requiring federal agencies to disconnect or mitigate affected Ivanti devices, and both CVEs were added to the KEV catalog with compressed remediation deadlines.
Mitigation guidance, patch availability, and the full advisory are linked above via NVD; Ivanti’s own security advisory carries the canonical remediation timeline.
