# PureBlog: admin image upload endpoint allows unrestricted file uploads

Link for people: https://infrastack.ai/live/CVE-2026-124635 (this .md is for agents)

PureBlog, a PHP blogging tool, has a flaw in its admin image upload script (admin/upload-image.php) that accepts files without proper restriction. A remote attacker may be able to upload files to the server, and the sources do not say whether that leads to code execution.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Look for admin/upload-image.php in the PureBlog install directory
- Check the installed version against `3.7.2` (versions up to and including it are affected)
- Run `unknown` for any other check: the sources do not give one

## Fix

- PureBlog: upgrade to `3.7.3`
