Description Avinash Hanwate 2022-12-29 03:54:40 UTC

HashiCorp Consul and Consul Enterprise up to 1.11.8, 1.12.4, and 1.13.1 do not check for multiple SAN URI values in a CSR on the internal RPC endpoint, enabling leverage of privileged access to bypass service mesh intentions. Fixed in 1.11.9, 1.12.5, and 1.13.2."
