Boundary Enterprise
Monthly
Network-accessible denial-of-service in HashiCorp Boundary workers allows unauthenticated remote attackers to block legitimate worker connections by manipulating TLS handshake timing during node enrollment. Attackers can connect to the worker authentication listener and intentionally delay or withhold client certificates, causing connection handlers to block and preventing legitimate workers from enrolling or routing traffic. Both Community Edition and Enterprise versions prior to 0.21.3, 0.20.3, and 0.19.5 are vulnerable. EPSS data not provided; no CISA KEV listing indicating limited observed exploitation. Vendor-confirmed vulnerability with patches released across three active release branches.
