GHSA-M5P4-GVPX-4MVR
Vulnerability from github – Published: 2026-05-11 14:43 – Updated: 2026-06-08 23:42Summary
GuardDog includes attacker-controlled filenames, file locations, messages, and code snippets in its default human-readable output without escaping terminal control characters. A malicious package can therefore inject ANSI or OSC escape sequences into analyst terminals or CI logs.
Description
The finding formatter stores file paths and snippets from scanned content:
location = file_path + ":" + str(start_line)
finding = {
"location": location,
"code": code,
"message": result["extra"]["message"],
}
The human-readable reporter later prints these values directly:
" * " + finding["message"] + " at " + finding["location"] + "\n " + _format_code_line_for_output(finding["code"])
No escaping is applied for control characters such as \x1b. A malicious package can therefore ship a filename like:
evil\x1b[2J.py
or matched source lines containing terminal escapes, which survive into the final CLI output.
Reproduction summary
- Create a file whose name contains
\x1b[2J. - Feed a semgrep-style result referencing that file into
Analyzer._format_semgrep_response(). - Render the result with
HumanReadableReporter.print_scan_results(). - The output string contains the raw escape bytes, which a terminal may interpret.
Key code paths
guarddog/analyzer/analyzer.py:377-392guarddog/reporters/human_readable.py:36-42guarddog/reporters/human_readable.py:84-91
Practical impact
This can be used to: - clear or rewrite analyst terminal output - inject misleading or spoofed log content in CI - emit clickable OSC 8 hyperlinks or title changes in compatible terminals
Prior public disclosure check
As of 2026-03-18, no matching public GitHub advisory, CVE, or public repo issue was found for this specific bug.
Suggested fix
Escape or strip terminal control characters before rendering any attacker-controlled value in human-readable output. This should cover package names, file paths, messages, and code snippets.

GHSA-M7CR-M3PV-HGRP
Vulnerability from github – Published: 2026-05-19 15:21 – Updated: 2026-06-08 23:42Impact
go-git's SSH transport constructs the remote exec command by wrapping the repository path in single quotes without escaping single quotes embedded inside the path. This diverges from canonical Git, which shell-quotes the path through sq_quote_buf so that an embedded ' becomes the '\'' close-escape-reopen sequence and the whole path round-trips as a single quoted argument.
A repository path containing a single quote can therefore break out of the quoted region in the exec command and be appended as additional shell tokens. On SSH servers that evaluate the exec command through a shell (for example a user account whose login shell is /bin/sh or /bin/bash, or a ForceCommand wrapper that re-evaluates $SSH_ORIGINAL_COMMAND), those additional tokens execute in that account's command-execution context. SSH servers that tokenize the exec command without shell evaluation, including the canonical git-shell setup, are not affected.
The vulnerable behaviour is on the SSH server side, not in go-git: the same bytes can be produced by any SSH client. The change in go-git is defense-in-depth that restores parity with canonical Git's wire format and prevents go-git from being a vehicle for reaching shell-evaluating servers through attacker-influenced repository paths.
Patches
Users should upgrade to a patched version in order to mitigate this issue. The fix ports sq_quote_buf from canonical Git into go-git's SSH transport so that the wire output is byte-identical to what git itself would send for the same input.
Versions prior to v5 are likely to be affected, users are recommended to upgrade to a supported go-git version.

Mitigation MIT-4.3
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, consider using the ESAPI Encoding control [REF-45] or a similar tool, library, or framework. These will help the programmer encode outputs in a manner less prone to error.
- Alternately, use built-in functions, but consider using wrappers in case those functions are discovered to have a vulnerability.
Mitigation MIT-27
Strategy: Parameterization
- If available, use structured mechanisms that automatically enforce the separation between data and code. These mechanisms may be able to provide the relevant quoting, encoding, and validation automatically, instead of relying on the developer to provide this capability at every point where output is generated.
- For example, stored procedures can enforce database query structure and reduce the likelihood of SQL injection.
Mitigation
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages. Study all expected communication protocols and data representations to determine the required encoding strategies.
Mitigation
In some cases, input validation may be an important strategy when output encoding is not a complete solution. For example, you may be providing the same output that will be processed by multiple consumers that use different encodings or representations. In other cases, you may be required to allow user-supplied input to contain control information, such as limited HTML tags that support formatting in a wiki or bulletin board. When this type of requirement must be met, use an extremely strict allowlist to limit which control sequences can be used. Verify that the resulting syntactic structure is what you expect. Use your normal encoding methods for the remainder of the input.
Mitigation
Use input validation as a defense-in-depth measure to reduce the likelihood of output encoding errors (see CWE-20).
Mitigation
Fully specify which encodings are required by components that will be communicating with each other.
Mitigation
When exchanging data between components, ensure that both components are using the same character encoding. Ensure that the proper encoding is applied at each interface. Explicitly set the encoding you are using whenever the protocol allows you to do so.
CAPEC-104: Cross Zone Scripting
An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security.
CAPEC-73: User-Controlled Filename
An attack of this type involves an adversary inserting malicious characters (such as a XSS redirection) into a filename, directly or indirectly that is then used by the target software to generate HTML text or other potentially executable content. Many websites rely on user-generated content and dynamically build resources like files, filenames, and URL links directly from user supplied data. In this attack pattern, the attacker uploads code that can execute in the client browser and/or redirect the client browser to a site that the attacker owns. All XSS attack payload variants can be used to pass and exploit these vulnerabilities.
CAPEC-81: Web Server Logs Tampering
Web Logs Tampering attacks involve an attacker injecting, deleting or otherwise tampering with the contents of web logs typically for the purposes of masking other malicious behavior. Additionally, writing malicious data to log files may target jobs, filters, reports, and other agents that process the logs in an asynchronous attack pattern. This pattern of attack is similar to "Log Injection-Tampering-Forging" except that in this case, the attack is targeting the logs of the web server and not the application.
CAPEC-85: AJAX Footprinting
This attack utilizes the frequent client-server roundtrips in Ajax conversation to scan a system. While Ajax does not open up new vulnerabilities per se, it does optimize them from an attacker point of view. A common first step for an attacker is to footprint the target environment to understand what attacks will work. Since footprinting relies on enumeration, the conversational pattern of rapid, multiple requests and responses that are typical in Ajax applications enable an attacker to look for many vulnerabilities, well-known ports, network locations and so on. The knowledge gained through Ajax fingerprinting can be used to support other attacks, such as XSS.
