CVE-2026-19268: Command Injection in abdullah1854 MCPGateway
A command injection vulnerability exists in the getUsageByDateRange function of the src/services/claude-usage.ts file in abdullah1854 MCPGateway up to commit 549f494a9e363f40530149de324b8097de424230. The vulnerability allows remote attackers to manipulate the 'since' argument to execute arbitrary commands. The project uses continuous delivery with rolling releases, so no specific affected versions or patches are currently identified. The vulnerability has a CVSS score of 6.3, indicating a medium severity impact, but the database rates it as low severity. No official fix or patch information is available, and the project has not responded to the issue report. Exploit code is publicly available, but no known exploitation in the wild has been reported.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-19268) affects the MCPGateway project by abdullah1854, specifically in the Claude Usage Range Endpoint component's getUsageByDateRange function. The issue arises from improper handling of the 'since' argument, leading to command injection (CWE-74). The vulnerability can be exploited remotely without user interaction and requires low privileges. The project uses continuous delivery with rolling releases, so no fixed or affected version numbers are provided. The vulnerability has a CVSS 3.1 score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L). The project was notified early but has not yet responded or issued a patch. Public exploit code exists, but no active exploitation is known.
Potential Impact
Successful exploitation allows an attacker with low privileges to remotely execute arbitrary commands via the 'since' argument in the getUsageByDateRange function. This can lead to partial confidentiality, integrity, and availability impacts. However, the overall severity is rated low by the database, and no active exploitation has been observed.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory or project repository for current remediation guidance. Since the project has not responded and no patch is available, users should monitor the project for updates and consider applying any future fixes promptly. Until a fix is released, avoid exposing the vulnerable endpoint to untrusted networks or restrict access to trusted users only.
