For versions through 2021.07.0, consider updating to a version later than 2021.07.0 to resolve the issue. As a temporary workaround, consider restricting access to the
common/password.c file or the affected hash comparison function until a patch is available. Found an issue in the description? Have something to add? Feel free to write us 👾
