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":"2026-05-13T22:16:46.057+00:00","modifiedAt":"2026-06-17T10:50:41.59+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","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://nvd.nist.gov/vuln/detail/CVE-2026-44471","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-59"],"productCriteria":["cpe:2.3:a:gitoxidelabs:gix-fs:*:*:*:*:*:rust:*:*"],"sourceDates":{"published":"2026-05-13T22:16:46.057","lastModified":"2026-06-17T10:50:41.590"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
