AppSec & Vulnerability Triage

How to triage CVE reports and GitHub Security Advisories in seconds.

Highlight NVD CVE descriptions, GitHub Security Advisories (GHSA), or vendor bulletins and extract affected versions, exploit preconditions, and remediation steps.

Best fit

Best for AppSec engineers, SREs, and developers triaging Dependabot, Snyk, and vendor vulnerability alerts.

On-screen walkthrough

How this looks on a real webpage.

Instead of switching tabs and rebuilding context, highlight the exact passage that slowed you down and press your shortcut (default: Ctrl+Shift+X or Cmd+Shift+X on macOS, fully customizable in settings).

github.com/advisories/GHSA-example-redos
Context: Detailed
1. Highlighted on page (GitHub Security Advisory (GHSA) — Transitive Dependency Alert)
Impact: Regular expression denial of service (ReDoS) in header parser when processing crafted Accept-Encoding values exceeding 4,096 characters. This vulnerability only affects deployments where the server is exposed directly to the internet without an upstream reverse proxy or CDN normalizing HTTP headers. Patched in 4.18.3 and 5.1.1.
Ctrl+Shift+X“Are we exploitable if our Node service sits behind Cloudflare and an AWS ALB? What is the fix?”
2. Vezz me on-screen answer overlay

1. **Exploitability in your setup**: Low / Mitigated. Exploitation requires raw `Accept-Encoding` headers >4,096 characters reaching the origin directly. Both Cloudflare and AWS ALB enforce header size bounds and normalize `Accept-Encoding`.

2. **Permanent Fix**: Upgrade the package to `>=4.18.3` (v4.x) or `>=5.1.1` (v5.x).

3. **Immediate Workaround**: Verify your ALB/CDN HTTP header limit is `<= 4KB`.

3. Suggested follow-up questions in thread
  • “Write a 2-sentence justification for our security ticket marking this CVE as low priority.”
  • “Explain the CVSS v3.1 vector string attached to this advisory.”
Step-by-step workflow

How to run this workflow in place.

1

Highlight the CVE technical description and impact block

On NVD, GitHub Security Advisories, or vendor release notes, select the description, CVSS vector, and affected component section.

2

Ask for exploit preconditions vs your architecture

Press Ctrl+Shift+X and ask what specific function call, configuration flag, or network exposure is required for an attacker to trigger the bug.

3

Extract remediation and mitigation rules

Ask Vezz me for the minimum patched version for your major branch plus any WAF or config-level workaround.

Key details

Why this approach works better than switching tabs.

Cut through Dependabot and Snyk alert fatigue
Modern projects pull in hundreds of transitive dependencies, and most high-CVSS advisories in sub-dependencies are only reachable under specific runtime conditions.
  • Separates theoretical vulnerability existence from actual exploit preconditions (e.g., requires untrusted input passed to a deprecated CLI flag)
  • Translates cryptic CVSS v3.1 and v4.0 vector strings (`AV:N/AC:H/PR:L/UI:N`) into concrete attacker requirements
  • Extracts exact affected version ranges and backported patch numbers across major release lines
Safe for security engineers: activeTab-only architecture
Security teams rightly refuse extensions that demand `<all_urls>` host permissions across internal dashboards.
  • Vezz me requests only `activeTab` and `storage`—zero background content scripts
  • Cannot read internal vulnerability trackers or SIEM dashboards unless you explicitly invoke `Ctrl+Shift+X`
  • Pairs directly with our downloadable Security Threat Modeler prompt preset

ApproachStrengthsTradeoffs
Vezz me on GHSA / NVD PageIsolating exact exploit preconditions and WAF workarounds in 10 secondsEvaluates the advisory text rather than scanning your local lockfile automatically

Frequently asked questions

Common questions about appsec & vulnerability triage.

Can Vezz me decode CVSS v3.1 and v4.0 vector strings?

Yes. Highlight a vector like CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N and ask Vezz me to explain what attacker privileges and preconditions are required.

Is Vezz me safe to install on a security engineer's browser?

Yes. Vezz me requests only activeTab and storage—it has zero background content scripts and cannot read internal vulnerability dashboards unless you explicitly invoke it.

Is there a dedicated prompt preset for threat modeling?

Yes, download our Security Threat Modeler preset from the Prompt Library.
