CVE-2026-48787: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in flipped-aurora gin-vue-admin
gin-vue-admin is an AI-assisted basic development platform. In version 2.9.1, an authenticated attacker with access to the code-generation feature and MCP management interface can exploit this vulnerability by injecting attacker-controlled Go source code through POST /autoCode/addFunc, and then invoking POST /autoCode/mcpStart to trigger a rebuild and restart of the standalone MCP service. This allows arbitrary operating system commands to be executed on the server with the privileges of the application process. Successful exploitation may lead to remote code execution (RCE), modification of backend source code or runtime logic, deployment of persistent backdoors, access to or manipulation of application data and configuration, and further impact on local resources running under the same service account or privilege context. The risk is highest in deployments that retain the source tree, allow writes to source files, and support local build or startup of standalone MCP components. In environments using binary-only releases, read-only filesystems, or with local build capabilities removed, the exploitability of the full attack chain is significantly reduced. However, once the online code-generation capability and MCP-hosted startup workflow are enabled, the overall security impact may reach high to critical severity. As of time of publication, it is unknown if a patched version is available. As a workaround, enforce strict allowlist validation on path- and identifier-related fields such as `humpPackageName`, `packageName`, `FuncName`, and `Router`, and only permit safe identifier formats.
AI Analysis
Technical Summary
The vulnerability in gin-vue-admin (CVE-2026-48787) allows an authenticated attacker with privileges to the code-generation and MCP management interfaces to perform OS command injection. By submitting attacker-controlled Go source code via the POST /autoCode/addFunc endpoint and then invoking POST /autoCode/mcpStart, the attacker can cause the MCP service to rebuild and restart with injected code. This leads to arbitrary OS command execution under the application's privilege context. The vulnerability is particularly severe in deployments that permit source code writes and local builds of MCP components. Deployments using binary-only releases or read-only filesystems have significantly reduced exploitability. No official patch or remediation is currently available. The vendor or community has not confirmed a fix. A mitigation involves enforcing strict allowlist validation on input fields such as humpPackageName, packageName, FuncName, and Router to ensure only safe identifier formats are accepted.
Potential Impact
Successful exploitation enables remote code execution on the server with the application's privileges. This can lead to modification of backend source code and runtime logic, deployment of persistent backdoors, unauthorized access to or manipulation of application data and configuration, and further compromise of local resources running under the same service account. The severity is high due to the potential for critical system compromise, especially in environments that allow source code modification and local builds.
Mitigation Recommendations
As of the publication date, no official patch or fix is available for this vulnerability. Users should enforce strict allowlist validation on path- and identifier-related input fields such as humpPackageName, packageName, FuncName, and Router to permit only safe identifier formats. Additionally, reducing the attack surface by disabling or restricting the code-generation feature and MCP-hosted startup workflow where possible can help mitigate risk. Deployments using binary-only releases or read-only filesystems significantly reduce exploitability. Monitor vendor advisories for updates on official patches or fixes.
