CVE-2026-20746Network attack vector

Service interruption via virtual-attribute memory leak

Published Jun 12, 2026 · Updated Jun 12, 2026

Memory exhaustion in Ping Identity PingDirectory affected releases allows remote authenticated users to interrupt directory service. When recent login history is enabled, virtual-attribute copying of values that reference ds-privilege-name fails to release Java heap memory. High privileges and passive interaction are required; repeated copying can exhaust the heap and disrupt the server and dependent identity services.
