How to fix?

Upgrade Debian:13 node-yarnpkg to version 1.21.1-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream node-yarnpkg package and not the node-yarnpkg package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

In Yarn before 1.21.1, the package install functionality can be abused to generate arbitrary symlinks on the host filesystem by using specially crafted "bin" keys. Existing files could be overwritten depending on the current user permission set.
