Ecosystem-wide dependent count for version 3.1.58.

DescriptionCVE.org

GitPython versions before 3.1.58 fail to validate options passed to git rm and git checkout commands in IndexFile.remove() and Head.checkout(). Attackers can supply --pathspec-from-file and --pathspec-file-nul parameters to read arbitrary files accessible to the process, with full file contents returned in GitCommandError.stderr.

AnalysisAI

Arbitrary file read in GitPython versions through 3.1.57 allows low-privileged users who can influence kwargs passed to IndexFile.remove() or Head.checkout() to exfiltrate the complete contents of any file readable by the hosting process. The attack chains two unsanitized Git flags - --pathspec-from-file and --pathspec-file-nul - causing Git to return verbatim file contents through a GitCommandError exception that GitPython surfaces in-band. …

Attack ChainAIDerived

Hypothetical attack flow derived from CVE metadata

Access
Authenticate to GitPython-consuming application
Delivery
Craft request with pathspec_from_file and pathspec_file_nul kwargs
Exploit
Application forwards kwargs to IndexFile.remove() or Head.checkout()
Execution
Git executes with --pathspec-from-file and --pathspec-file-nul flags
Persist
Unmatched pathspec error returns target file contents verbatim

Vulnerability AssessmentAI

Exploitation Exploitation requires that an attacker can influence the **kwargs argument passed to either IndexFile.remove() or Head.checkout() in a GitPython-consuming application - specifically, supplying the pathspec_from_file key (mapping to --pathspec-from-file) pointing to an attacker-chosen file path, combined with pathspec_file_nul=True (mapping to --pathspec-file-nul). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 7.1 (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N) reflects a network-reachable, low-complexity flaw with low-privilege prerequisites and high confidentiality impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with low-privilege access to a web application that offers Git repository management via GitPython submits a crafted API request supplying pathspec_from_file='/etc/passwd' and pathspec_file_nul=True as parameters, which the application forwards without validation to repo.index.remove() or repo.heads[0].checkout(). GitPython passes these as --pathspec-from-file and --pathspec-file-nul to the underlying git subprocess; Git returns the file contents verbatim in an unmatched-pathspec error, which GitPython surfaces via GitCommandError.stderr. …
Remediation The primary fix is upgrading GitPython to version 3.1.58 or later, which introduces option sanitization at the affected call sites. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, conduct emergency inventory of all GitPython deployments running version 3.1.57 or earlier and identify which systems allow untrusted user input to influence parameters passed to IndexFile.remove() or Head.checkout() methods. …
