Attack Chain

1. An attacker identifies a vulnerable application using GitPython to clone repositories.
2. The attacker crafts a malicious string containing a Git configuration option, such as --config core.hooksPath=/path/to/malicious/hooks, embedded within a seemingly benign option string like --branch main --config core.hooksPath=/path/to/malicious/hooks.
3. The attacker injects this malicious string into the multi_options parameter of the clone_from(), clone(), or Submodule.update() methods.
4. GitPython’s _clone() function validates the multi_options parameter using Git.check_unsafe_options() before it is processed by shlex.split().
5. Because the malicious string starts with a safe option (--branch), it bypasses the validation check.
6. The shlex.split() function then transforms the string into a list of individual options, making the --config option active.
7. The git clone command is executed with the injected --config core.hooksPath=/path/to/malicious/hooks option, causing Git to use the attacker-controlled directory for Git hooks.
8. Git executes the malicious hooks (e.g., post-checkout), resulting in arbitrary code execution on the victim’s machine.

Impact

Successful exploitation of this vulnerability allows an attacker to execute arbitrary code on the system where the GitPython library is used. Any application that passes user-supplied input to the multi_options parameter of the affected functions is vulnerable. This can lead to complete system compromise, data exfiltration, or denial of service. The vulnerability affects GitPython versions prior to 3.1.47.

Recommendation

2. The attacker finds an endpoint or function where they can control kwargs passed to Repo.clone_from(), Remote.fetch(), Remote.pull(), or Remote.push().
3. The attacker crafts a malicious payload, using underscore-form kwargs such as upload_pack or receive_pack, setting their value to a command they want to execute (e.g., a shell script path or a direct command).
4. The application or system, using a vulnerable version of GitPython, receives these kwargs and bypasses the intended safety check.
5. GitPython’s Git.transform_kwarg() method converts the underscore-form kwargs into their corresponding hyphenated Git options (e.g., upload_pack becomes --upload-pack).
6. The Git command is executed with the attacker-controlled option, leading to arbitrary command execution on the system.
7. The attacker gains unauthorized access, potentially stealing credentials, modifying repositories, or moving laterally within the network.

Impact

Successful exploitation of this vulnerability can lead to severe consequences, especially in web applications, CI/CD systems, and automation tools that rely on GitPython for repository management. Attackers could steal SSH keys, API tokens, cloud credentials, or other sensitive information. They could also modify repositories, build outputs, or release artifacts, leading to supply chain attacks. In CI/CD environments, this vulnerability could enable lateral movement from worker nodes or compromise the entire automation infrastructure.

4. The extracted summary, which includes the malicious payload, is passed as the corpus parameter to the vulnerable _extractLLM() function in src/gep/signals.js.
5. The _extractLLM() function constructs a curl command by concatenating strings, embedding the unsanitized corpus parameter within the command string.
6. The curl command is executed using execSync(), which interprets the shell metacharacters and executes the injected commands.
7. The injected commands are executed with the privileges of the Node.js process.
8. The attacker achieves remote code execution, enabling them to perform actions such as data exfiltration or system compromise.

Impact

Successful exploitation of this vulnerability allows an attacker to execute arbitrary commands on the server hosting the evolver application.

Recommendation

• Inspect web server logs for suspicious requests targeting main.py with unusual characters or command-like syntax in the command parameter, and deploy the “GitPilot-MCP Command Injection Attempt” Sigma rule to detect exploitation attempts.
• Monitor process creation events for unexpected processes spawned by the GitPilot-MCP application, using the “GitPilot-MCP Suspicious Child Process” Sigma rule to identify potentially malicious activity.
• Implement input validation and sanitization for all user-supplied input, especially the command argument in the repo_path function, to prevent command injection attacks.
• Apply any available patches or updates for GitPilot-MCP as soon as they are released to address the vulnerability.
• Consider deploying a web application firewall (WAF) to filter out malicious requests targeting the repo_path function.

Attack Chain

1. An attacker identifies a vulnerable instance of FastlyMCP running a version up to commit 6f3d0b0e654fc51076badc7fa16c03c461f95620.
2. The attacker crafts a malicious HTTP request targeting the fastly-mcp.mjs file.
3. The malicious request includes a manipulated command argument containing OS command injection payloads.
4. The FastlyMCP application processes the request, passing the attacker-controlled command argument to an underlying OS command execution function without proper sanitization.
5. The injected OS command is executed by the server with the privileges of the FastlyMCP application.
6. The attacker gains arbitrary code execution on the server, enabling further malicious activities.
7. The attacker may then establish persistence via web shells or by modifying system configurations.
8. Ultimately, the attacker achieves complete control over the system, potentially leading to data theft, service disruption, or further lateral movement within the network.

Impact

Successful exploitation of CVE-2026-7220 allows attackers to execute arbitrary OS commands on the affected system. This can lead to full system compromise, potentially resulting in data breaches, service disruption, and lateral movement to other systems within the network. The lack of specific versioning information due to the rolling release model makes identifying and patching vulnerable instances challenging, potentially increasing the number of victims.

Recommendation

• Monitor web server logs for suspicious requests targeting fastly-mcp.mjs with unusual parameters in the query string to detect potential exploitation attempts (see the Sigma rule Detect FastlyMCP Command Injection Attempt).
• Implement input validation and sanitization for the command argument in fastly-mcp.mjs to prevent command injection, though patching is preferable.
• Deploy the Sigma rule Detect Suspicious Process Execution via FastlyMCP to identify potential malicious process execution originating from FastlyMCP.

Attack Chain

1. The attacker identifies a vulnerable instance of choieastsea simple-openstack-mcp running a version up to 767b2f4a8154cca344344b9725537a58399e6036.
2. The attacker crafts a malicious HTTP request targeting the server.py endpoint responsible for handling exec_openstack function calls.
3. Within the HTTP request, the attacker injects OS commands into a parameter that is processed by the exec_openstack function without proper sanitization.
4. The server.py script receives the crafted request and passes the attacker-controlled input directly to a shell interpreter, such as os.system() or subprocess.Popen().
5. The injected OS commands are executed with the privileges of the user running the simple-openstack-mcp application.
6. The attacker gains arbitrary code execution on the server, allowing them to perform actions such as installing malware, creating new user accounts, or accessing sensitive data.
7. The attacker may then use the compromised server as a pivot point to further compromise the internal network.

Impact

Successful exploitation of CVE-2026-7066 allows a remote attacker to execute arbitrary OS commands on the affected system. This can lead to full system compromise, data theft, and potential disruption of services. Given the nature of OpenStack environments, this could impact multiple virtual machines and cloud resources.

Recommendation

• Examine web server logs for requests targeting server.py with unusual parameters or command-like syntax, which can indicate exploitation attempts. Implement the first Sigma rule provided.
• Deploy the second Sigma rule to detect suspicious processes spawned by the web server that may be the result of command injection.
• Monitor network connections originating from the server running simple-openstack-mcp for unusual outbound traffic to external IPs which might signal data exfiltration or C2 communication after a successful exploit using the third Sigma rule.
• Apply input validation and sanitization to the exec_openstack function within server.py to prevent command injection.
• While specific patch information is unavailable, closely monitor the choieastsea simple-openstack-mcp project for updates addressing CVE-2026-7066.
