CVE-2026-26015: CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') in arc53 DocsGPT
DocsGPT is a GPT-powered chat for documentation. From version 0.15.0 to before version 0.16.0, an attacker accessing both the official DocsGPT website or any local and public deployment, can craft a malicious payload bypassing the "MCP test" behavior to achieve arbitrary remote code execution (RCE). This issue has been patched in version 0.16.0.
AI Analysis
Technical Summary
DocsGPT, a GPT-powered documentation chat tool by arc53, contained a command injection vulnerability (CWE-77) in versions from 0.15.0 to before 0.16.0. This flaw allowed attackers to bypass the "MCP test" and execute arbitrary code remotely without authentication or user interaction. The vulnerability is rated with a CVSS 4.0 score of 10.0, indicating critical severity with network attack vector, no required privileges or user interaction, and high impact on confidentiality, integrity, and availability. The vulnerability was publicly disclosed on April 29, 2026, and patched in version 0.16.0.
Potential Impact
Successful exploitation results in unauthenticated remote code execution on affected DocsGPT instances, potentially compromising system confidentiality, integrity, and availability. This can lead to full system compromise where DocsGPT is deployed. No exploits in the wild have been reported so far.
Mitigation Recommendations
Upgrade affected DocsGPT installations to version 0.16.0 or later, where this vulnerability has been patched. Since this is not a cloud service, users must apply the update themselves. Patch status is confirmed by the vendor's versioning information. No additional mitigations are specified.
