CVE-2026-110858
Description
A flaw was found in GitPython. This vulnerability allows an attacker to achieve arbitrary code execution on the host system. The issue occurs because the Remote.pull() function inspects only keyword arguments for unsafe command options and fails to validate positional repository reference specifications (refspecs). By supplying crafted refspecs containing command-line flags, an attacker can execute arbitrary operating system commands with the privileges of the calling process.
Statement
This flaw is evaluated as having Critical impact because successful exploitation enables unauthenticated remote code execution with the full privileges of the host service whenever untrusted repository reference strings are processed. In Red Hat environments such as Ansible Automation Platform and OpenShift AI, GitPython manages automated repository synchronization workflows that may become exposed if external inputs govern branch definitions. However, execution is contingent on using SSH or local filesystem transports, whereas interactions strictly using HTTPS remotes render the injected parameters inert.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Confidentiality,Integrity,Availability,Other
Technical Impact: Execute Unauthorized Code or Commands; Alter Execution Logic; Read Application Data; Modify Application Data
If an attacker can provide an untrusted input that contains argument-separating delimiters, then the resulting command will have more arguments than intended by the developer, potentially changing the expected behavior of the command. Depending on the functionality supported by the extraneous arguments, this may have security-relevant consequences. The attacker could include arguments that allow unintended commands or code to be executed, allow sensitive data to be read or modified, or cause other unintended behavior.
