GitPython is a python library used to interact with Git repositories. Prior to version 3.1.48, a vulnerability in GitPython allows attackers who can supply a crafted reference path to an application using GitPython to write, overwrite, move, or delete files outside the repository’s .git directory via insufficient validation of reference paths in reference creation, rename, and delete operations. This issue has been patched in version 3.1.48.

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8303-1 advisory.

    Santos Gallegos discovered that GitPython did not properly validate paths when resolving certain Git     references. An attacker could possibly use this issue to cause files outside the .git directory to be     accessed, leading to a denial of service. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS,     Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2023-41040)

    Wes Ring discovered that GitPython did not properly block certain unsafe Git options when they were     provided as Python keyword arguments. An attacker could possibly use this issue to cause arbitrary command     execution. (CVE-2026-42215)

    It was discovered that GitPython did not properly validate clone options before processing them. An     attacker could possibly use this issue to inject unsafe Git configuration, leading to arbitrary command     execution through Git hooks. This issue only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04     LTS, and Ubuntu 26.04 LTS. (CVE-2026-42284)

    It was discovered that GitPython did not properly validate reference paths during reference operations. An     attacker could possibly use this issue to write, overwrite, move, or delete files outside the repository.
    (CVE-2026-44243)

    Dan Aridor discovered that GitPython did not properly validate configuration values before writing them to     Git configuration files. An attacker could possibly use this issue to inject unsafe Git configuration,     leading to arbitrary command execution through Git hooks. (CVE-2026-44244)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - GitPython is a python library used to interact with Git repositories. Prior to version 3.1.48, a     vulnerability in GitPython allows attackers who can supply a crafted reference path to an application     using GitPython to write, overwrite, move, or delete files outside the repository's .git directory via     insufficient validation of reference paths in reference creation, rename, and delete operations. This     issue has been patched in version 3.1.48. (CVE-2026-44243)

Note that Nessus relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by a vulnerability referenced in the following CVE:
