Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

PDM versions before 2.27.0 write project-local files such as pdm.toml without checking for symlinks. A malicious repository that places a symlink at one of these paths can cause local PDM commands, such as pdm config -l, to overwrite the symlink target as the invoking user. The attacker needs the victim to run such a command in the prepared checkout. Upgrade to PDM 2.27.0 or later, which fixes the issue.
