Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Hashicorp Consul versions 1.9.0 up to but not including 1.20.1 are affected, as are Consul Enterprise builds in that range. Using header matching in L7 traffic intentions can allow requests to bypass HTTP header-based access rules. The source gives few details about who can trigger this or how. Upgrade to Consul 1.20.1 or later.
