FABC-782 Fabric CA API operational metrics FABC-789 Fabric CA database operations metrics FABC-743 Fabric CA health check Changes, Known Issues, and Workarounds -------------------------------------- FAB-11096 - Docker images with Alpine Linux Bash is no longer available in Fabric images. Utilize Alpine's built-in sh or ash instead. Known Vulnerabilities --------------------- FABC-174 Commands can be manipulated to delete identities or affiliations This vulnerability can be resolved in one of two ways: 1) Use HTTPS (TLS) so that the authorization header is not in clear text. 2) The token generation/authentication mechanism was improved to optionally prevent token reuse. In v1.4 a more secure token can be used by setting environment variable: FABRIC_CA_SERVER_COMPATIBILITY_MODE_V1_3=false However, it cannot be set to false until all clients have been updated to generate the more secure token and tolerate FABRIC_CA_SERVER_COMPATIBILITY_MODE_V1_3=false. The Fabric CA client has been updated in v1.4 to generate the more secure token. The Fabric SDKs will be updated by v2.0 timeframe to generate the more secure token, at which time the default for Fabric CA server will change to: FABRIC_CA_SERVER_COMPATIBILITY_MODE_V1_3=false Resolved Vulnerabilities ------------------------ None.
