# dimasma0305/CVE-2026-111497-POC

> PoC for CVE-2026-111497: a malformed Brotli stream triggers an out-of-bounds write in Node.js decoders, reaching RCE in three lab profiles. Ships with local Docker labs, a scanner, and defender detection rules.

- Magnitude: 1.5 out of 10 — Steady
- Stars: 60 total · +0 stars measured 2026-10-27, 10:04–11:02 UTC, ≈ 4 by evening
- Star trust: star growth looks organic
- Category: Security · Language: Python · Created: 2026-10-22 · Last push: 2026-10-25

## Useful for

- Reproduce RCE in an isolated Express 5.3.0 Docker lab via poc.py
- Scan an asset list for affected Node.js versions with scan.py
- Set up Suricata detection for the exploit via reflected id output

## Why it’s here

- Star-counter measurements on 2026-10-27 (UTC), 10:04–11:02: 60 → 60 stars (+0). This is the change over that interval.
- Estimated end-of-day forecast: about +4 stars, using observed gains and the previous day.
- The repository is 5 days old and already has 60 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 16
- Issues and pull requests: 11
- Watchers: 0
- Average over the last week: 10 per day
- Usual pace: too little history (under two weeks)
- Stars in the last hour (measured): 0

## Stars per day, last 6 days (oldest → newest, today is partial)

2026-10-22 … 2026-10-27: 8, 21, 11, 6, 13, 0

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
