q-koa@13.8.54
AI Security Review
scanned 27d ago · by lpm-firewall-aiq-koa is a Koa admin framework with no install lifecycle, but its find handler executes request-body include and relate strings through vm.runInNewContext while the default JWT check allows any URL containing find. That is a concrete unauthenticated code-execution and SQL-injection flaw in the running server, not a hidden supply-chain payload.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
An HTTP request to a model find route, including one whose path contains find, with include or relate in the body, or a system count request with a model name.
Impact
An unauthenticated client can run attacker-controlled JavaScript inside the server process and can alter the SQL statement used to read table metadata. This is a framework vulnerability, not an install-time malware chain.
Mechanism
formatPostFunction wraps the body string in eval and vm.runInNewContext runs it, then the returned function is invoked with the application object. The JWT middleware calls next when url.includes matches the default whitelist entry find. The system query concatenates the model value into SQL.
AI rationale
q-koa is a Koa admin framework with no install lifecycle, but its find handler executes request-body include and relate strings through vm.runInNewContext while the default JWT check allows any URL containing find. That is a concrete unauthenticated code-execution and SQL-injection flaw in the running server, not a hidden supply-chain payload.
Evidence
core/app.jscore/file/plugins/system/controller.js
Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Critical Vulnerability with medium false-positive risk.
Evidence for warning
- Model find handlers take include and relate from the HTTP body, wrap them as eval(...), and run them with vm.runInNewContext, then call the result with the live app object.
- The default JWT whitelist contains the substring find, and a failed token still continues when the URL includes any whitelist entry, the method is GET, the URL contains a dot, or the client is treated as local.
- The system plugin interpolates the request model name into a raw INFORMATION_SCHEMA SQL string.
- package.json has no preinstall, install, or postinstall hook; its scripts are ordinary debug, pm2 serve, and shell PATH commands.
Evidence against
- No child_process, install-time execution, credential harvest, or hidden outbound recipient was found.
- The eval path is the framework's Sequelize include builder, not a separate payload dropper.
- Outbound HTTP usage is in payment, map, WeChat, and Douyin service modules.
