Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: High: There is a total loss of confidentiality, resulting in all information within the Vulnerable System being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Detectable: no evidence on record.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 29 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

A fix is available in GitPython version 2.24.0 that extends the denylist to cover the missing options. Users should upgrade to version 2.24.0 or later. Alternatively, embedding applications should restrict or sanitize options passed to Repo.archive() to prevent unsafe options like --add-file and --add-virtual-file. The vendor advisory recommends either implementing an allowlist of safe options or extending the denylist consistently to cover all filesystem path or URL options.

Description

GitPython's Repo.archive() method uses a denylist to block unsafe git archive options that could lead to security issues. However, the denylist is incomplete and omits the options --add-file and --add-virtual-file, which allow reading arbitrary files from the filesystem and injecting attacker-controlled content into archives. This flaw enables an attacker who can influence Repo.archive() options to read arbitrary files with the privileges of the running process. The vulnerability does not allow code execution but exposes sensitive file contents. A fix is available in GitPython version 2.24.0.

Impact

An attacker able to influence the options passed to GitPython's Repo.archive() can read arbitrary files on the filesystem with the privileges of the process running GitPython. This can lead to disclosure of sensitive information. There is no direct code execution impact. The vulnerability requires the embedding application to forward caller-controlled options to Repo.archive().

Summary

The vulnerability in GitPython arises because the unsafe_git_archive_options denylist consulted by Repo.archive() is incomplete. While options like --exec and --output are blocked to prevent arbitrary command execution and writing to arbitrary filesystem paths, the options --add-file and --add-virtual-file are not included in the denylist. These options allow reading arbitrary files from the filesystem and injecting attacker-chosen content into the archive, respectively. This gap permits an attacker who can supply options to Repo.archive() to exfiltrate arbitrary file contents at the process privilege level. The issue was confirmed with a proof-of-concept demonstrating reading an out-of-tree file. The vulnerability is similar to a prior issue with unsafe_git_clone_options denylist omissions. The recommended remediation is to either implement an allowlist of safe options or extend the denylist to include these missing options. The vulnerability affects GitPython versions >=2.1.0 and <2.24.0 and is fixed in 2.24.0.
