How to fix?

Upgrade Debian:10 apt to version 0.8.15.10 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream apt package and not the apt package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

The pkgAcqMetaClearSig::Failed method in apt-pkg/acquire-item.cc in Advanced Package Tool (APT) 0.8.11 through 0.8.15.10 and 0.8.16 before 0.8.16~exp13, when updating from repositories that use InRelease files, allows man-in-the-middle attackers to install arbitrary packages by preventing a user from downloading the new InRelease file, which leaves the original InRelease file active and makes it more difficult to detect that the Packages file is modified and unsigned.
