07 Remediation
Upgrade Bifrost HTTP transport to 2.0.0 or later. The fix (PR #5763) refuses create and update of a non-builtin plugin path when the request was let through because dashboard authentication is disabled or unconfigured (403), and replaces the plugin downloader with an SSRF-hardened client. The 1.6.x line through 1.6.11 does not include this change.
