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 cloning a repository Git knows to optionally fetch a bundle advertised by the remote server, which allows the server-side to offload parts of the clone to a CDN. The Git client does not perform sufficient validation of the advertised bundles, which allows the remote side to perform protocol injection. This protocol injection can cause the client to write the fetched bundle to a location controlled by the adversary. The fetched content is fully controlled by the server, which can in the worst case lead to arbitrary code execution. The use of bundle URIs is not enabled by default and can be controlled by the bundle.heuristic config option. Some cases of the vulnerability require that the adversary is in control of where a repository will be cloned to. This either requires social engineering or a recursive clone with submodules. These cases can thus be avoided by disabling recursive clones. 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.

The Microsoft Visual Studio Products are missing security updates. It is, therefore, affected by multiple vulnerabilities.

  - Vulnerability in Gitk where when a user clones an untrusted repository and runs Gitk without additional     command arguments, any writable file can be created and truncated. The option 'Support per-file encoding'     must have been enabled. (CVE-2025-27613)

  - Vulnerability in Gitk where a Git repository can be crafted in such a way that a user who has cloned the     repository can be tricked into running any script supplied by the attacker by invoking gitk filename,     where filename has a particular structure. (CVE-2025-27614)

  - Improper link resolution before file access ('link following') in Visual Studio allows an unauthorized     attacker to elevate privileges over a network. (CVE-2025-49739)

    Git development team reports:
    CVE-2025-27613: Gitk:
                 When a user clones an untrusted repository and runs Gitk without                  additional command arguments, any writable file can be created and                  truncated. The option Support per-file encoding must have been                  enabled. The operation Show origin of this line is affected as                  well, regardless of the option being enabled or not.

    CVE-2025-27614: Gitk:
                A Git repository can be crafted in such a way that a user who has                 cloned the repository can be tricked into running any script                 supplied by the attacker by invoking `gitk filename`, where                 `filename` has a particular structure.

    CVE-2025-46835: Git GUI:
                When a user clones an untrusted repository and is tricked into                 editing a file located in a maliciously named directory in the                 repository, then Git GUI can create and overwrite any writable                 file.

    CVE-2025-48384: Git:
                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.

    CVE-2025-48385: Git:
                When cloning a repository Git knows to optionally fetch a bundle                 advertised by the remote server, which allows the server-side to                 offload parts of the clone to a CDN. The Git client does not                 perform sufficient validation of the advertised bundles, which                 allows the remote side to perform protocol injection.
                This protocol injection can cause the client to write the fetched                 bundle to a location controlled by the adversary. The fetched                 content is fully controlled by the server, which can in the worst                 case lead to arbitrary code execution.

    CVE-2025-48386: Git:
                The wincred credential helper uses a static buffer (`target`) as a                 unique key for storing and comparing against internal storage. This                 credential helper does not properly bounds check the available                 space remaining in the buffer before appending to it with                 `wcsncat()`, leading to potential buffer overflows.
