Prior to 0.21.1, a malicious tree can be constructed that will, when checked out with gitoxide, permit writing an attacker-controlled symlink into any existing directory the user has write access to. During checkout, all symlink index entries are deferred and created after regular files using a single shared gix_worktree::Stack. Internally, this uses a gix_fs::Stack. gix_fs::Stack::make_relative_path_current() caches validated path prefixes: when the previously-processed leaf component exactly matches the leading component(s) of the next path, the leaf-to-directory transition at gix-fs/src/stack.rs invokes only delegate.push_directory(), never delegate.push(). In gix_worktree::stack::delegate::StackDelegate, when the state member is State::CreateDirectoryAndAttributesStack, Attributes::push_directory() only loads attributes (from the ODB, in the clone case), and does not perform any other checks. The on-disk symlink_metadata() check and unlink-on-collision live in StackDelegate::push()'s invocation of create_leading_directory(), which is therefore bypassed for the cached prefix. The final symlink is created with plain std::os::unix::fs::symlink, which follows symlinks in parent directories. Therefore, it's possible to provide a tree with duplicate symlink and directory entries that exploits this. This vulnerability is fixed in 0.21.1.","state":0,"publishedAt":"2026-05-13T21:36:44.007+00:00","modifiedAt":"2026-05-14T12:59:51.324+00:00","affected":[{"ecosystem":"Vendor product","name":"gitoxide","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"GitoxideLabs\",\n                    \"product\": \"gitoxide\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.21.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://github.com/GitoxideLabs/gitoxide/security/advisories/GHSA-f89h-2fjh-2r9q"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-44471","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-44471","identifiers":["CVE-2026-44471"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
