dulwich is vulnerable to Path Traversal
81
High Risk
This Affects:
dulwichTL;DR
Several dulwich work-tree update paths did not fully enforce core.protectNTFS and core.protectHFS, so a crafted branch merged or pulled via update_working_tree could still materialize NTFS-unsafe names such as git~2 even after the 1.2.5 hardening reached only checkout and reset. Untrusted patch headers processed by apply_patches (for example during git am) could also carry +++ or rename targets with .. or absolute paths that were joined onto the repository root and written outside the working tree. The fix derives the configured path validator for all work-tree updates, rejects out-of-tree patch targets, and adds defense-in-depth validation in checkout, restore, and reset_file.
