CVE-2026-41140

by ·

Poetry is a dependency manager for Python. Prior to 2.3.4, the extractall() function in src/poetry/utils/helpers.py:410-426 extracts sdist tarballs without path traversal protection on Python versions where tarfile.data_filter is unavailable. Considering only Python versions which are still supported by Poetry, these are 3.10.0 – 3.10.12 and 3.11.0 – 3.11.4. This vulnerability is fixed in 2.3.4.
