1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsReview AI-generated code as you would any other code, but also check the packages it suggests and the permissions of the AI agent that produced it. Before merging, verify dependencies, trace untrusted data into sensitive operations, test authorization failures, run code and dependency analysis, and restrict the agent’s access to commands, files, credentials, and networks. A passing scan—or an AI-generated review—is not proof that code is secure.
How to fix common security flaws in AI-generated code
Use this workflow before merging or releasing AI-suggested changes. It covers both flaws in the source code and risks created by the development agent. Apply the secure coding practices appropriate to your language, framework, and environment; a model’s output does not get a different security standard.
- Make the security requirement explicit. Identify the data, trust boundaries, permissions, and sensitive operations affected by the change. Review the code’s data flow against those requirements.
- Verify every new dependency. Confirm the exact package exists in the intended registry and is the one the project needs. Check its provenance, maintainers, age, and maintenance history before installing or merging it.
- Audit dependency versions. Run the audit tool appropriate to the ecosystem, check current vulnerability information, and update or pin versions through your normal dependency process. Configure CI to block vulnerabilities that violate your project’s severity policy.
- Trace untrusted data to sensitive operations. Inspect flows into SQL, shell commands, HTML, templates, file paths, deserializers, and other interpreters. Validate and parameterize or encode values for the specific sink and framework.
- Test permissions and failure cases. Check authentication, authorization, tenant separation, and least privilege. Add negative tests showing that unauthorized users cannot access or change protected data.
- Review, analyze, and triage. Use code review and static or other code analysis, investigate findings, and record fixes through the normal development workflow. Manually inspect high-impact changes and the threat model before release.
- Constrain the agent. If it can run commands, edit files, install packages, or use the network, limit it to what the task requires. Protect credentials and sensitive directories, and review changes to dependencies, build scripts, CI, deployment settings, and persistent agent instructions.
NIST’s Secure Software Development Framework (SSDF) is lifecycle guidance for developing secure software, not a guarantee that any model-generated change is safe. NIST SP 800-218A is a final July 2024 AI-specific profile intended to be used with SSDF 1.1. NIST lists SP 800-218 Rev. 1 Version 1.2 as an initial public draft published December 17, 2025—not as a final revision. See NIST SP 800-218A and the NIST SSDF publication record.
Check dependencies for fake, malicious, or vulnerable packages
Confirm a suggested package is real and appropriate
AI-generated code may name a package that does not exist, or a plausible name that an attacker has registered. Do not blindly run a suggested installation command. Search the exact name in the intended package registry; check provenance and maintainers, package age, and maintenance history; and ask whether the project needs another dependency at all. Prefer an established, approved package where one meets the need. In managed environments, use approved-package allowlists or installation policies.

Check versions against current vulnerability information
A model may suggest a version based on outdated information. Run the ecosystem’s dependency audit and check a current vulnerability source. OWASP lists npm audit, pip audit, govulncheck, and cargo audit as examples; the right choice depends on the project’s ecosystem. Pin the selected version and update it using the team’s normal process. Make CI block dependencies that breach your severity policy. OWASP’s Secure Coding with AI Cheat Sheet discusses both dependency hallucinations and outdated dependencies.
Prevent injection and unsafe input or output handling
Treat user input and AI-related content as untrusted: prompts, retrieved documents, tool results, and model outputs can all carry hostile or malformed data. Trace these values through the application rather than assuming an AI-generated change handles them safely.
Rank #2
- For SQL: use parameterized queries rather than concatenating untrusted values into query text.
- For shell commands: avoid building executable command strings from untrusted values; use safe APIs and validate arguments for the operation.
- For HTML and templates: encode output for the relevant context and use framework protections appropriately.
- For paths and deserialization: validate values against the intended format and allowed locations or types before use.
A generic “sanitize” step is not enough for every interpreter. The correct defense depends on where a value goes: validation should reject values outside the expected rules, while parameterization or context-appropriate encoding prevents data from being treated as executable syntax. NIST SP 800-218A says to log, analyze, and validate inputs and outputs in the model context, and to sanitize or drop problematic values. Its PW.5.1 recommendation R3 states: “Encode inputs and outputs to prevent the execution of unauthorized code.” Read the NIST SP 800-218A publication.
Catch missing authorization and insecure design
Code can compile and pass happy-path tests while still allowing the wrong person to see or change data. Compare the generated change with the application’s security requirements and trace who can reach each sensitive operation.
- Confirm authentication is required where the operation needs it.
- Check authorization for the specific resource and action, not merely whether a user is signed in.
- Verify tenant boundaries so one customer cannot access another customer’s data.
- Use least privilege for application accounts, services, and tools.
- Add negative tests for unauthenticated, unauthorized, and cross-tenant access, along with expected-behavior tests.
These are practical checks to apply established secure coding practices to the application; they should not be read as a measured claim that AI-generated code omits these controls at a particular rate. NIST SSDF describes secure development practices across the lifecycle, while SP 800-218A adds guidance for generative AI and dual-use foundation models. See SP 800-218A and the SSDF 1.1 publication.
Protect the development environment from unsafe agent actions
Source review alone will not address every risk if an AI agent can execute commands, install packages, read files, or access the network. Malicious or misleading text in a repository or tool response may influence an agent, so treat that context as untrusted input too.
Rank #4
- Run agents in a constrained environment, such as a development container or ephemeral workspace.
- Allow only the commands and filesystem access needed for the task.
- Keep secrets, SSH material, cloud credentials, and sensitive directories out of reach where possible.
- Limit outbound network access when the task does not need it.
- Review repository issues, pull requests, READMEs, dependency files and changelogs, fetched pages, and tool responses as potentially adversarial content.
- Inspect persistent agent instruction files and changes to build, CI, and deployment configuration before accepting them.
These controls limit workflow exposure; they do not replace inspection and testing of the resulting code. OWASP discusses indirect prompt injection, tool risks, sandboxing, context leakage, and agent changes to automation in its Secure Coding with AI Cheat Sheet.

- Every new package exists, is the intended package, and has acceptable provenance and maintenance history.
- The relevant dependency audit has run, and vulnerabilities are handled under the project’s severity policy.
- Untrusted values have been traced into interpreters and sensitive operations, with validation, parameterization, or encoding chosen for each context.
- Authorization, tenant boundaries, and failure cases have been tested against explicit security requirements.
- Code review and analysis findings have been triaged, and required fixes recorded.
- The agent had only the commands, files, credentials, and network access required; its dependency and automation changes have been reviewed.
- High-impact changes and the threat model have received human review before release.
NIST presents review and analysis as ways to identify vulnerabilities so they can be corrected, not as proof that none remain. A clean automated scan or AI-generated review therefore cannot establish that a change is secure. NIST’s guidance is in SP 800-218A and SSDF 1.1.
