consul v1.12.5 Release Notes

Release Date: 2022-09-20 // over 1 year ago

  • 💥 BREAKING CHANGES:

    • 🚀 ca: If using Vault as the service mesh CA provider, the Vault policy used by Consul now requires the update capability on the intermediate PKI's tune mount configuration endpoint, such as /sys/mounts/connect_inter/tune. The breaking nature of this change will be resolved in an upcoming 1.12 patch release. Refer to upgrade guidance for more information.

    🔒 SECURITY:

    • auto-config: Added input validation for auto-config JWT authorization checks. Prior to this change, it was possible for malicious actors to construct requests which incorrectly pass custom JWT claim validation for the AutoConfig.InitialConfiguration endpoint. Now, only a subset of characters are allowed for the input before evaluating the bexpr. [GH-14577]
    • connect: Added URI length checks to ConnectCA CSR requests. Prior to this change, it was possible for a malicious actor to designate multiple SAN URI values in a call to the ConnectCA.Sign endpoint. The endpoint now only allows for exactly one SAN URI to be specified. [GH-14579]

    👌 IMPROVEMENTS:

    • 🔧 envoy: adds additional Envoy outlier ejection parameters to passive health check configurations. [GH-14238]
    • metrics: add labels of segment, partition, network area, network (lan or wan) to serf and memberlist metrics [GH-14161]
    • snapshot agent: (Enterprise only) Add support for path-based addressing when using s3 backend.
    • 💻 ui: Reuse connections for requests to /v1/internal/ui/metrics-proxy/ [GH-14521]

    🐛 BUG FIXES:

    • ⚡️ ca: Fixed a bug with the Vault CA provider where the intermediate PKI mount and leaf cert role were not being updated when the CA configuration was changed. [GH-14516]
    • cli: When launching a sidecar proxy with consul connect envoy or consul connect proxy, the -sidecar-for service ID argument is now treated as case-insensitive. [GH-14034]
    • 🚚 connect: Fixed a bug where old root CAs would be removed from the primary datacenter after switching providers and restarting the cluster. [GH-14598]
    • 🏗 connect: Fixed an issue where intermediate certificates could build up in the root CA because they were never being pruned after expiring. [GH-14429]
    • 🔧 envoy: validate name before deleting proxy default configurations. [GH-14290]
    • rpc: Adds max jitter to client deadlines to prevent i/o deadline errors on blocking queries [GH-14233]
    • 🚚 ui: Removed Overview page from HCP instalations [GH-14606]
