A buffer overflow was addressed with improved bounds checking. This issue is fixed in Xcode 26.1. A user in a privileged network position may be able to cause a denial-of-service.
An out-of-bounds write issue was addressed with improved input validation. This issue is fixed in Xcode 26.1. Processing a maliciously crafted file may lead to heap corruption.
A path handling issue was addressed with improved validation. This issue is fixed in Xcode 26. Processing an overly large path value may crash a process.
Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals. When reading a config value, Git strips any trailing carriage return and line feed (CRLF). When writing a config entry, values with a trailing CR are not quoted, causing the CR to be lost when the config is later read. When initializing a submodule, if the submodule path contains a trailing CR, the altered path is read resulting in the submodule being checked out to an incorrect location. If a symlink exists that points the altered path to the submodule hooks directory, and the submodule contains an executable post-checkout hook, the script may be unintentionally executed after checkout. This vulnerability is fixed in v2.43.7, v2.44.4, v2.45.4, v2.46.4, v2.47.3, v2.48.2, v2.49.1, and v2.50.1.
This issue was addressed with improved permissions checking. This issue is fixed in Xcode 16. An app may be able to inherit Xcode permissions and access user data.
