## What it is
A security research writeup documenting zero-click, wormable remote code execution vulnerabilities in Microsoft Teams, reported to MSRC in 2020. It details the bug chain, Microsoft's 'Important, Spoofing' rating controversy, and the disclosure timeline.

## Use cases
- learn how zero-click RCE bug chains work in desktop apps
- study real-world vulnerability disclosure against Microsoft MSRC
- understand how chat message rendering can lead to code execution
- research Electron app security weaknesses
- teach examples of severity rating disputes in bug bounties

## When to choose
- you want a detailed real-world RCE writeup for learning security research
- you're studying responsible disclosure and vendor rating practices
- you research messaging app attack surfaces

## When to avoid
- you need a working exploit tool or scanner
- you need current vulnerabilities - these bugs were fixed in late 2020
- you need actionable defensive tooling rather than a narrative writeup

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: security, penetration-testing, vulnerability-scanning
- domain: security, developer-tools
- platform: cross-platform
- tags: security-research, vulnerability-writeup, microsoft-teams, rce, bug-bounty, zero-click
