CVE-2026-24046 Backstage has a Possible Symlink Path Traversal in Scaffolder Actions

Backstage is an open framework for building developer portals. Multiple Scaffolder actions and archive extraction utilities were vulnerable to symlink-based path traversal attacks. An attacker with access to create and execute Scaffolder templates could exploit symlinks to read arbitrary files vi...

CVE-2026-23986

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...

GHSA-XJHM-GP88-8PFX Copier safe template has arbitrary filesystem read access via symlinks when _preserve_symlinks: false

Impact 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 include arbitrary files/directories outsid...

Symlink Poisoning

node-tar is vulnerable to Symlink Poisoning. The vulnerability is due to insufficient sanitization of hardlink and symlink linkpath values during archive extraction, where malicious tar entries can bypass the extraction root restriction and overwrite arbitrary files or create dangerous symlinks...
