More information:

It was discovered that zstd, a compression utility, temporarily exposed a world-readable version of its input even if the original file had restrictive permissions.

For the stable distribution (buster), this problem has been fixed in version 1.3.8+dfsg-3+deb10u1.

We recommend that you upgrade your libzstd packages.
