SCA: security update for copier (GHSA-4fqp-r85r-hxqh)
medium Tenable Self-Hosted Container Security Plugin ID 436884
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Copier is a library and CLI app for rendering project templates. Prior to version 9.11.2, Copier suggests
that it's safe to generate a project from a safe template, i.e. one that doesn't use unsafe features like
custom Jinja extensions which would require passing the `--UNSAFE,--trust` flag. As it turns out, a safe
template can currently write to arbitrary directories outside the destination path by using directory a
symlink along with `_preserve_symlinks: true` and a generated directory structure whose rendered path is
inside the symlinked directory. This way, a malicious template author can create a template that
overwrites arbitrary files (according to the user's write permissions), e.g., to cause havoc. Version
9.11.2 patches the issue. (CVE-2026-23986)
