Impact

CVSS 8.0 (High). KEV-listed — actively exploited. Git is the most widely used VCS. Config injection enables code execution via hooks. Affects development environments and CI/CD pipelines. Credential theft through helper manipulation.
Exploit ScenarioDerived

An attacker who can influence Git config values (through a cloned repository's .gitmodules, a crafted clone URL, or a Git server response) injects a trailing CR that allows escaping the current config line. Additional injected config entries set core.hooksPath to a directory containing malicious hooks, or modify credential.helper to redirect credentials to the attacker. On the next Git operation (pull, push, commit), the malicious hook executes or credentials are stolen.
Act Now Prioritize within 24-48h. Why: In CISA KEV with patch available.

AnalysisAIv1 – Mar 16, 2026

Git contains a CRLF injection vulnerability (CVE-2025-48384, CVSS 8.0) in its config handling that allows attackers to escape header lines and modify config values. KEV-listed, this vulnerability in the world's most widely used version control system enables config injection attacks that could lead to arbitrary code execution through Git hooks, credential theft, or repository manipulation.

Earlier versions of this analysis (1)
v1 Mar 16, 2026 - 04:21 CVSS 8.0

Git's config writing logic (CWE-59) fails to properly quote values containing trailing carriage returns, allowing attackers to inject additional config entries that modify Git's behavior, potentially enabling code execution or credential theft.

RemediationAI

Update Git immediately. Review .gitconfig and repository configs for suspicious entries. Audit core.hooksPath and credential.helper settings. Enterprise: deploy Git updates through software management.

Technical ContextAI · show details

When Git writes a config entry, it strips trailing CRLF from values but does not quote values containing only a trailing CR. This allows an attacker who can influence config values to inject additional lines into the git config file. Injected config entries could: set malicious hooks (core.hooksPath), modify credential helpers (credential.helper), change remote URLs, or alter other security-sensitive settings. Git config is implicitly trusted by Git operations.

DescriptionCVE.org

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.

Executive ViewAI

Why It Matters

Organizations using Git face notable risk from CVE-2025-48384 rated CVSS 8.0. Successful exploitation could significantly impact the confidentiality, integrity, or availability of affected systems. This vulnerability is actively exploited in the wild (KEV-listed) and requires immediate remediation. Immediate patching is required per CISA KEV mandate.

Business Impact: Severe
Compensating Controls

Apply vendor patch. If immediate patching is not feasible: (1) Implement network-level access controls to limit exposure; (2) Enable enhanced monitoring and alerting; (3) Apply principle of least privilege.
