Hi,

The following vulnerability was published for pdm.

CVE-2023-45805[0]:
| pdm is a Python package and dependency manager supporting the latest
| PEP standards. It's possible to craft a malicious `pdm.lock` file
| that could allow e.g. an insider or a malicious open source project
| to appear to depend on a trusted PyPI project, but actually install
| another project. A project `foo` can be targeted by creating the
| project `foo-2` and uploading the file `foo-2-2.tar.gz` to pypi.org.
| PyPI will see this as project `foo-2` version `2`, while PDM will
| see this as project `foo` version `2-2`. The version must only be
| `parseable as a version` and the filename must be a prefix of the
| project name, but it's not verified to match the version being
| installed. Version `2-2` is also not a valid normalized version per
| PEP 440. Matching the project name exactly (not just prefix) would
| fix the issue. When installing dependencies with PDM, what's
| actually installed could differ from what's listed in
| `pyproject.toml` (including arbitrary code execution on install). It
| could also be used for downgrade attacks by only changing the
| version. This issue has been addressed in commit `6853e2642df` which
| is included in release version `2.9.4`. Users are advised to
| upgrade. There are no known workarounds for this vulnerability.
