## Overview

WordPress Core is vulnerable to Remote Code Execution in versions 4.7 through 7.1.3. This is due to predictable, web-accessible staging paths used during full-package core upgrades. This makes it possible for unauthenticated attackers to execute code on the server during the upgrade window.

## Affected

- `WordPress >= 4.7.0 <= 4.7.38`
- `WordPress >= 4.8.0 <= 4.8.33`
- `WordPress >= 4.9.0 <= 4.9.34`
- `WordPress >= 5.0.0 <= 5.0.30`
- `WordPress >= 5.1.0 <= 5.1.27`
- `WordPress >= 5.2.0 <= 5.2.29`
- `WordPress >= 5.3.0 <= 5.3.26`
- `WordPress >= 5.4.0 <= 5.4.24`
- `WordPress >= 5.5.0 <= 5.5.23`
- `WordPress >= 5.6.0 <= 5.6.22`
- `WordPress >= 5.7.0 <= 5.7.20`
- `WordPress >= 5.8.0 <= 5.8.18`
- `WordPress >= 5.9.0 <= 5.9.19`
- `WordPress >= 6.0.0 <= 6.0.17`
- `WordPress >= 6.1.0 <= 6.1.15`
- `WordPress >= 6.2.0 <= 6.2.14`
- `WordPress >= 6.3.0 <= 6.3.13`
- `WordPress >= 6.4.0 <= 6.4.13`
- `WordPress >= 6.5.0 <= 6.5.13`
- `WordPress >= 6.6.0 <= 6.6.10`
- `WordPress >= 6.7.0 <= 6.7.10`
- `WordPress >= 6.8.0 <= 6.8.11`
- `WordPress >= 6.9.0 <= 6.9.10`
- `WordPress >= 7.0.0 <= 7.0.7`
- `WordPress >= 7.1.0 <= 7.1.3`
