ImpactA PyYAML-related Remote Code Execution RCE vulnerability, namely CVE-2020-14343, is exposed in docling-core =2.21.0, 2.48.4 and, specifically only if the application uses pyyaml 5.4 and invokes doclingcore.types.doc.DoclingDocument.loadfromyaml passing it untrusted YAML data. PatchesThe...

PYSEC-2026-1272 Copier safe template has arbitrary filesystem write access via directory symlinks when _preserve_symlinks: true

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 write to arbitrary directories outside the...
