In detail

Each finding: the path, the line, the fix.

  • Reachable flaws

    Traced from an entry point, such as GET /users/:id, down to the sink.

  • The exploit path

    The route, the file and the line, so anyone on the team can reproduce it.

  • Framework-aware data flows

    Express, Spring, Django, Rails, Laravel, ASP.NET, Gin, Fastify and the major ORMs.

  • A fix with each finding

    A patch in your editor, or a signed pull request with a regression test.

  • Your policy

    Severity and scope set per team. Block at the pull request, or only warn.

Everything it checks

What our SAST sees that yours misses.

One real finding per language, with the flagged line and its fix.

  • JavaScript (Express)

    Cross-site scripting. The name from the query string lands in the HTML unescaped.

    HighCWE-79
    res.send(`<h1>Hi ${req.query.name}</h1>`);res.send(`<h1>Hi ${escapeHtml(req.query.name)}</h1>`);

  • TypeScript (Fastify)

    Authorization bypass (IDOR). Any signed-in user can read any invoice by changing the id.

    HighCWE-639
    return db.invoice.findUnique({ where: { id } });return db.invoice.findFirst({ where: { id, ownerId: req.user.id } });

  • Python (Django)

    SQL injection. The search term is spliced into the SQL, so a quote rewrites the query.

    CriticalCWE-89
    cursor.execute(f"SELECT * FROM books WHERE title = '{q}'")cursor.execute("SELECT * FROM books WHERE title = %s", [q])

  • Go (Gin)

    Path traversal. A name like ../../etc/passwd walks out of the uploads folder.

    HighCWE-22
    c.File(filepath.Join("uploads", name))c.File(filepath.Join("uploads", filepath.Base(name)))
12 more languages, one finding each

  • Java (Spring)

    XML external entities. The parser resolves external entities, so an upload can read local files.

    HighCWE-611
    var doc = dbf.newDocumentBuilder().parse(f.getInputStream());dbf.setAttribute(XMLConstants.ACCESS_EXTERNAL_DTD, "");

  • Kotlin (Spring)

    Weak password hash. MD5 is fast and unsalted: leaked hashes are cheap to crack.

    HighCWE-916
    val md = MessageDigest.getInstance("MD5")users.save(form.email, encoder.encode(form.password))

  • C# / .NET (ASP.NET)

    Open redirect. returnUrl can be any site, so the login ends on an attacker's page.

    MediumCWE-601
    return Redirect(returnUrl);return LocalRedirect(returnUrl);

  • Ruby (Rails)

    Mass assignment. permit! accepts every attribute, admin included.

    HighCWE-915
    @user.update(params.require(:user).permit!)@user.update(params.require(:user).permit(:name, :email))

  • PHP (Laravel)

    Unsafe deserialization. A crafted cookie is unserialized into live objects.

    CriticalCWE-502
    $cart = unserialize($request->cookie('cart'));$cart = json_decode($request->cookie('cart'), true);

  • Rust

    OS command injection. The file name reaches a shell: a name with ; runs a command.

    CriticalCWE-78
    Command::new("sh").arg("-c").arg(cmd).status()Command::new("convert").args([name, "thumb.png"]).status()

  • Swift

    Token stored in cleartext. The session token sits in UserDefaults, readable from a device backup.

    MediumCWE-312
    UserDefaults.standard.set(reply.token, forKey: "token")try keychain.save(reply.token, account: "token")

  • Scala

    Weak random for a reset token. scala.util.Random is predictable, so reset tokens can be guessed.

    HighCWE-338
    val token = Random.alphanumeric.take(32).mkStringval token = UUID.randomUUID().toString

  • Elixir (Phoenix)

    Cross-site request forgery. Browser routes take POSTs from any site, no CSRF token checked.

    HighCWE-352
    plug :fetch_sessionplug :protect_from_forgery

  • Solidity

    Reentrancy. Ether leaves before the balance drops, so withdraw can be re-entered.

    CriticalCWE-841
    payable(msg.sender).call{value: amount}("");balances[msg.sender] -= amount;payable(msg.sender).transfer(amount);

  • C / C++

    Buffer overflow. A name longer than 31 bytes overflows the stack buffer.

    CriticalCWE-120
    strcpy(name, argv[1]);snprintf(name, sizeof name, "%s", argv[1]);

  • HTML

    Missing integrity check. No integrity hash: a tampered CDN file runs with full page access.

    MediumCWE-353
    <script src="https://cdn.example/chart.js"></script><script src="/static/vendor/chart.js"></script>
Real-time code security, where your code lives.

Errors and warnings pile up while the agent writes. Caught before the pull request.

  • Real-Time Feedback

    Scan and secure your code in real time during the development process, agent-time, not nightly CI.

  • Hybrid AI Technology

    Our solution combines large language models with traditional taint and reachability analysis.

  • Collaboration Tools

    Findings flow into Jira, GitHub Issues, GitLab Issues and Slack.

  • Comprehensive Language Support

    Eighteen languages, every web framework worth shipping.

  • Automated Fixes & Remediation

    AI-generated patches arrive directly in the IDE or as a signed PR with a regression test attached.

  • Customizable Policies

    Tune severity, scope and per-team scoping. Block at PR or warn-only.

  • Developer-Centric Reporting

    Every finding ships with a 3-line plain-English explanation, the reproducible exploit path, the file and line, and the suggested patch.

From flag to fix

  • The line is flagged.

    Exploitable and reachable, not a pattern match.

  • Judged in the loop.

    Your rules loaded, a verdict before the save.

  • Fixed at the line.

    The agent rewrites it in the same session.

Frequently asked about CybeDefend SAST.

How is CybeDefend SAST different from legacy scanners like Semgrep, Snyk Code or Checkmarx?
Legacy SAST runs on commits and buries the real issues in noise. When Ghost Security ran pattern-based scanners over nearly 3,000 open-source repositories in 2025, more than 91% of the flagged vulnerabilities turned out to be false positives. CybeDefend runs at agent-time on the diff your AI agent is about to write, before the file is even saved. We combine reachability tracing (does this taint path actually reach a sink?), framework-aware data-flow models covering Express, Spring, Django, Rails, ASP.NET, and the major ORMs, plus exploit-path scoring to rank findings by real exploitability rather than pattern match count. On production repos, our verified queue stays tight enough to triage in minutes rather than days. We also ship verified AI-generated fixes alongside every finding, most legacy scanners stop at the alert. The result: drastically fewer false positives, security enforced before the PR exists, and automated remediation your agent can apply in the same session.
Which languages and frameworks do you support?
Eighteen languages: JavaScript, TypeScript, Python, Go, Java, Kotlin, Rust, C# / .NET, Ruby, PHP, Swift, Scala, Elixir, Solidity, plus C / C++, HTML and more. Framework-aware data-flow models cover Express, Spring, Django, Rails, Phoenix, Laravel, ASP.NET, Gin, Fastify and the major ORMs. New frameworks ship monthly.
Does CybeDefend SAST integrate with my existing IDE and CI?
Yes. We ship a native MCP server, so any MCP-compatible agent (Claude Code, Cursor, Windsurf, GitHub Copilot, Gemini) consumes verdicts directly. Dedicated plugins ship for VS Code and the JetBrains family (IntelliJ, PhpStorm, WebStorm, PyCharm, DataGrip, Rider, CLion, RustRover, GoLand, RubyMine, AppCode). First-class CI integration on GitHub Actions and GitLab CI; a REST API and CLI cover any other system you run.
What about false positives?
Hybrid AI plus reachability tracing pushes false positives toward zero on the verified queue. Findings the engine cannot confirm are tagged as 'reachable but cold' or 'unreachable' and demoted, never paged. Net result on real customer repos: drastically fewer false positives across SAST, SCA, IaC and secrets, with the verified queue staying tight enough to triage in minutes, not days.
