Summary
Consul Community Edition and Consul Enterprise versions 1.18.21 through 2.0.2 are vulnerable to a partial arbitrary file read when configured to use the Vault Connect CA provider with JWT or AppRole authentication. A privileged attacker with `operator:write` permission may direct Consul to read and forward credential files outside the intended scope, potentially leading to exfiltration of sensitive secrets from the Consul server host.
Risk Assessment
An attacker could gain access to sensitive files, including secrets, potentially leading to compromise of the entire infrastructure.
Recommendation
Upgrade Consul to version 2.0.3 (Community) or the appropriate Enterprise version (1.21.17, 1.22.11, 2.0.3).
