v1.2.0

VulnGate — a Codex-native source-audit pipeline for ANY codebase: libraries (parsing/serialization), web frameworks (Spring/Struts), middleware/servers (Tomcat/Jetty), logging libraries (Log4j/Logback), expression engines, message/RPC stacks, and applications. Runs the S1→S8 audit loop (attack-surface map → candidates → source audit → PoC matrix → novelty gate → CVSS → disclosure-ready report) with hard evidence gates (G0–G5) driven by the host agent. Aliases: @vulngate, @vg, 漏洞审计, 源码审计, 审计管线, vuln audit. Coverage-driven auditing: full source inventory, heuristic call graphs and flows, security control gaps, sibling differentials, candidate scheduling, and macOS/Electron/native application reconstruction.

Install vulngate for Codex

Installs for the current user
codex plugin marketplace add IchenDEV/agent-plugin-mkt
codex plugin marketplace upgrade agent-plugin-marketplace
codex plugin add vulngate@agent-plugin-marketplace

Paste and run these commands in a terminal with Codex. They add and refresh the PluginsMP catalog, then install this plugin.

The installer fetches third-party code from the source repository shown on this page. This directory validates manifest structure and source location, but does not perform a security audit; review the manifest, components, and source before installing.

Get the source manually
git clone https://github.com/xingchen20lj/vulngate

Clone the source repository, then follow its setup instructions to add the plugin to a compatible client. The repository root is the plugin root.

Drive the VulnGate S1→S8 source-audit pipeline natively in Codex. Use when the user asks to audit any kind of source code — libraries (parsing/serialization/JSON/XML/YAML), web frameworks (Spring/Struts), middleware/servers (Tomcat/Jetty), logging libraries (Log4j/Logback), expression engines, message/RPC stacks (Dubbo/Netty/Hessian), or applications — for RCE/DoS/info-disclosure/logic flaws; verify a PoC across a version×feature×precondition matrix; run the novelty gate against upstream issues/PRs and public disclosures; compute CVSS with precondition consistency; or produce a disclosure-ready finding report; or audit a macOS desktop client (.app/.dmg/.pkg — Swift, Objective-C, C/C++, Electron or bundled Java) through the adapter bundled in macos/. Aliases: 漏洞审计, 源码审计, 0day 挖掘, PoC 验证, Novelty 核验, macOS 审计, 桌面客户端审计, 审 dmg/app/pkg.

The host agent owns reasoning; the bundled CLI owns deterministic work (PoC matrix, novelty scan, CVSS consistency, ledger). Every \"confirmed\" finding requires runtime PoC evidence; upstream public disclosure degrades novelty; never claim 0day without it.\n\n新增完整源码覆盖率、启发式调用图、安全控制缺口与同族差分、候选调度,以及 macOS .app/.dmg/.pkg、Mach-O、Electron ASAR 和 source map 适配。静态线索不替代运行时证据。",
