2 things to look at
- 21 days oldThe repository was created 21 days ago. New is not bad, but a brand new repository carrying a familiar-sounding name is the shape a typosquat arrives in, and there has been no time for anyone else to find a problem with it.
- 5 stars5 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.
What its author says it does
Copied from the file, not written here
Perform a threat-informed audit of trust boundaries, injection, secrets, browser controls, dependencies, and abuse cases. Activate automatically for every production-bound application when that concern is relevant to a software-engineering request.

forge-security: Application security
Purpose
Perform a threat-informed audit of trust boundaries, injection, secrets, browser controls, dependencies, and abuse cases.
This is an agent playbook, not a claim of standalone analyzer coverage. Apply
fullstack-forge/references/shared/module-contract.md
for common applicability, evidence, command-safety, mutation, verification, and completion rules.
Never hide failed checks or claim that an operation ran when it did not.
Automatic activation signals
Activate when a request or direct repository evidence involves application security, when
the user explicitly names forge-security, or when discovery proves an applicable boundary.
- Every production-bound application
- Security-sensitive changes
When not to activate
- No exemption; scope may be reduced for non-executable documentation
Automated support
Relevant discovery inputs are:
- project and architecture profile
- trust boundaries
- dependency and secret scan outputs
Available deterministic support, where present:
- Use
scan-secret-patternsfor its bounded evidence when present; treat unavailable runtime evidence asNOT_VERIFIED. - Use
inspect-routesfor its bounded evidence when present; treat unavailable runtime evidence asNOT_VERIFIED. - Use
inspect-auth-boundariesfor its bounded evidence when present; treat unavailable runtime evidence asNOT_VERIFIED. - Use
inspect-authorizationfor its bounded evidence when present; treat unavailable runtime evidence asNOT_VERIFIED. - Use
inspect-dependenciesfor its bounded evidence when present; treat unavailable runtime evidence asNOT_VERIFIED.
Agent inspection procedure
- Model the attack surface from discovery: entry points, trust boundaries, secrets, and the assets behind each.
- Trace untrusted input from every entry point to execution sinks (SQL, shell, template, deserialization, HTTP clients, file paths), recording interpolation versus binding at each sink.
- Inspect browser-boundary controls: output encoding, CSRF protection, CORS policy, security headers, and cookie flags on the actual responses.
- Search for secrets in code, configuration, templates, and history; verify error responses and logs do not leak internals or sensitive data.
- Run available dependency, static, and secret scanners, separating confirmed findings from pattern matches, and check rate limiting and abuse controls on expensive or state-changing operations.
Manual inspection requirements:
- Review business-logic abuse and chained attack paths
- Validate production-only controls with operators
Stack-specific guidance:
- Use framework-native escaping and query parameterization at the final sink
Evidence to collect
For formal findings, also follow fullstack-forge/references/PROTOCOL.md. Record the module's
inspected boundary, relevant tests, direct observations, and unavailable evidence.
Primary standards used as criteria, not proof of compliance:
- OWASP ASVS 5.0
- OWASP Cheat Sheet Series
- NIST SSDF
Common production failures
- Model assets, actors, entry points, trust boundaries, abuse cases, and mitigations
- Inspect injection, XSS, CSRF, SSRF, deserialization, path handling, redirects, headers, CORS, secrets, logging, and denial-of-service limits
- Run available dependency, static, and secret checks while distinguishing confirmed evidence from pattern matches
Missing-control checks
For every applicable criterion below, attach direct evidence or record a reasoned
NOT_APPLICABLE, NOT_VERIFIED, or BLOCKED status. The list is a routing checklist, not
evidence by itself.
- SQL injection
- NoSQL injection
- OS command injection
- Template injection
- Expression-language injection
- Header injection
- CRLF injection
- Log injection
- CSV and formula injection
- HTML injection
- JavaScript injection
- Cross-site scripting
- CSRF
- SSRF
- Path traversal
- Unsafe redirects
- Unsafe deserialization
- Request smuggling risks
- CORS
- Security headers
- Secret exposure
- Weak cryptography
- Hard-coded credentials
- Sensitive logging
- Error leakage
- Rate limiting
- Denial-of-service exposure
- Business-logic abuse
- Authentication weaknesses
- Authorization weaknesses
- Admin endpoints
- Debug endpoints
- Internal endpoints
- Dependency risks
- Prompt injection
- Unsafe shell execution
- Race conditions
- Mass assignment
- Prototype pollution
- ReDoS
- Session attacks
- OWASP ASVS, OWASP API Security, and NIST SSDF evidence
Commands and tools
- Run
forge security audit --jsonorfullstack-forge security audit --jsonwhen an explicit audit is requested and the CLI is installed. Normal feature work does not require it. - Use the deterministic support named above only for its documented bounded evidence.
Safe fixes
- Parameterize known trust-boundary inputs, redact secrets, and add straightforward security headers
- Add allowlists and explicit size limits
Approval-required changes
- Disabling controls, rotating secrets, or changing authentication, network, or production infrastructure
Verification
- Re-run scanners and targeted exploit regression tests
- Confirm every PASS has direct evidence
Completion contract
Apply the shared module contract and the module-specific limitations below.
Known limitations
- This audit is not a penetration test and must not be represented as one
