Fixes

Solution

Upgrade to a fixed boks-client release newer than 8.1.0.29 or 9.0.0.5, then rotate machine-account passwords generated by affected versions.


Workaround

Until fixed builds are deployed, avoid running adjoin join or autoupdate operations from affected versions. If automatic machine-account password renewal is enabled, disable it temporarily or ensure renewed passwords are rotated again after upgrading to a fixed version.
