URL Path Injection in Apache Gravitino

Executive Summary

This vulnerability is a URL path injection issue in Apache Gravitino. It occurs because user-supplied identifiers are not properly encoded before being used in URL paths, which can allow an attacker to manipulate the URL path in unintended ways.

Detection Guidance

Detecting this vulnerability involves checking for unencoded user-supplied identifiers in URL paths constructed by the MCP REST client in Apache Gravitino versions 1.0.0 through 1.2.0. Since the issue allows path traversal attacks, you can look for signs of unusual API endpoint access or unexpected path manipulation.

To detect potential exploitation attempts, you can monitor network traffic or logs for requests containing path traversal sequences (e.g., '../' or encoded variations like '%2e%2e%2f') targeting Apache Gravitino endpoints. Below are some suggested commands or approaches:

• Check Apache Gravitino logs for unusual URL patterns or path traversal attempts. Example command to search logs: grep -r '\.\./\|%2e%2e%2f' /var/log/gravitino/
• Use network monitoring tools like tcpdump or Wireshark to capture and analyze HTTP requests to Gravitino. Example tcpdump command: tcpdump -i eth0 -A 'port 80 or port 443' | grep -E '\.\./|%2e%2e%2f'
• Verify the installed version of Apache Gravitino. If it is between 1.0.0 and 1.2.0, the system is vulnerable. Upgrade to version 1.2.1 or later to mitigate the issue.

If you are using a web application firewall (WAF), ensure it is configured to block path traversal attempts targeting Gravitino endpoints.

Compliance Impact

The vulnerability CVE-2026-41041, a URL path injection issue in Apache Gravitino, can impact compliance with standards and regulations like GDPR and HIPAA due to its potential to expose sensitive data or allow unauthorized access to API endpoints.

Under GDPR, this vulnerability could lead to a breach of personal data if attackers exploit the path traversal to access unintended endpoints containing user information. GDPR requires organizations to implement appropriate technical measures to protect personal data, and a failure to mitigate such vulnerabilities could result in non-compliance, fines, or legal consequences.

For HIPAA, if the affected system processes or stores protected health information (PHI), the vulnerability could enable unauthorized access to PHI, violating the HIPAA Security Rule. This rule mandates safeguards to ensure the confidentiality, integrity, and availability of electronic PHI. Exploitation of this vulnerability could lead to a reportable breach under HIPAA, triggering notification requirements and potential penalties.

• Non-compliance risk: Organizations failing to patch or mitigate this vulnerability may be deemed non-compliant with data protection regulations.
• Data exposure: The vulnerability could lead to unauthorized access to sensitive data, directly conflicting with GDPR and HIPAA requirements.
• Remediation obligations: Both GDPR and HIPAA require timely remediation of vulnerabilities that could compromise data security. Upgrading to version 1.2.1 or later is necessary to maintain compliance.
