CVE-2026-7062: Intina47 context-sync RCE Vulnerability

CVE-2026-7062 Overview

A security vulnerability has been detected in Intina47 context-sync up to version 2.0.0. This affects an unknown part of the file src/git-integration.ts of the component Git Integration. Such manipulation leads to OS command injection, allowing attackers to execute arbitrary operating system commands through the vulnerable component. The attack can be executed remotely, and the exploit has been disclosed publicly and may be used.

Critical Impact
Remote OS command injection vulnerability in the Git Integration component allows attackers to execute arbitrary system commands on affected systems running context-sync versions up to 2.0.0.

Affected Products

Intina47 context-sync up to version 2.0.0
Systems utilizing the Git Integration component (src/git-integration.ts)

Technical Details for CVE-2026-7062

Vulnerability Analysis

This vulnerability is classified as CWE-77 (Improper Neutralization of Special Elements used in a Command), commonly known as command injection. The flaw exists within the Git Integration component of the context-sync application, specifically in the src/git-integration.ts file. When user-controlled input is passed to system commands without proper sanitization, attackers can inject malicious shell commands that will be executed with the privileges of the application.

The vulnerability is network-accessible, meaning attackers can exploit it remotely without requiring local access to the target system. Given that the exploit has been publicly disclosed, there is an elevated risk of active exploitation attempts in the wild.

Root Cause

The root cause of this vulnerability stems from improper input validation and sanitization in the Git Integration component. When the application processes Git-related operations, user-supplied data appears to be concatenated directly into shell commands without adequate escaping or parameterization. This allows special shell characters and command separators to be interpreted as executable instructions rather than data.

TypeScript/JavaScript applications that spawn shell processes using functions like child_process.exec() or similar without proper input validation are particularly susceptible to this class of vulnerability. The vulnerable code path in src/git-integration.ts fails to neutralize command injection sequences before constructing system commands.

Attack Vector

The attack vector is network-based, allowing remote exploitation without authentication. An attacker can craft malicious input containing shell metacharacters (such as ;, |, &&, ||, backticks, or $() constructs) that break out of the intended command context and execute arbitrary commands.

For example, if the Git Integration component accepts repository URLs or branch names that are passed to shell commands, an attacker could inject payloads that execute additional commands on the underlying operating system. This could lead to data exfiltration, system compromise, lateral movement, or establishing persistent access to the affected system.

Technical details and proof-of-concept information can be found in the GitHub Issue #31 and the public exploit documentation.

Detection Methods for CVE-2026-7062

Indicators of Compromise

Unusual child process spawning from Node.js or TypeScript applications running context-sync
Unexpected outbound network connections from the context-sync application
Shell command execution logs showing suspicious patterns with semicolons, pipes, or command substitution
Unauthorized file access or modification in directories accessible by the context-sync process

Detection Strategies

Monitor for anomalous process trees where node or ts-node processes spawn unexpected shell commands
Implement application-level logging to capture all inputs processed by the Git Integration component
Deploy endpoint detection rules to identify command injection patterns in process command lines
Review web application firewall logs for requests containing shell metacharacters targeting context-sync endpoints

Monitoring Recommendations

Enable verbose logging for the context-sync application to capture all Git-related operations
Configure SIEM alerts for process creation events with suspicious command-line arguments
Monitor file integrity for unexpected changes in the context-sync installation directory
Track network connections from application processes to identify potential data exfiltration

How to Mitigate CVE-2026-7062

Immediate Actions Required

Audit all deployments of Intina47 context-sync and identify instances running version 2.0.0 or earlier
Restrict network access to the context-sync application to trusted sources only
Implement input validation at the network perimeter to filter known command injection patterns
Consider temporarily disabling the Git Integration feature until a patch is available

Patch Information

Organizations should monitor the official context-sync repository for security updates and patch releases. Review GitHub Issue #31 for the latest information on remediation status. Additional vulnerability details are available through VulDB #359637.

Workarounds

Implement strict input validation and sanitization for all user-controlled data before processing
Use parameterized command execution methods instead of shell string concatenation
Deploy a web application firewall (WAF) with rules to block command injection attempts
Run the context-sync application with minimal system privileges to limit the impact of exploitation

bash

# Example: Restrict application permissions and network access
# Create dedicated user with minimal privileges
useradd -r -s /bin/false context-sync-user

# Run application with restricted permissions
sudo -u context-sync-user node /path/to/context-sync

# Implement firewall rules to restrict access
iptables -A INPUT -p tcp --dport 3000 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 3000 -j DROP
