Authorization bypass for session deletion in the transaction API

An authenticated caller with network access to the Consul server RPC port could delete arbitrary sessions without holding the required permission. This vulnerability, CVE-2026-19016, is fixed in Consul 2.0.3 and Consul Enterprise 1.21.17, 1.22.11, and 2.0.3.
