CVE-2026-6611 Details
Description
A vulnerability was found in liangliangyy DjangoBlog up to 2.1.0.0. This affects an unknown function of the file djangoblog/settings.py of the component File Upload Endpoint. Performing a manipulation of the argument SECRET_KEY results in use of hard-coded cryptographic key . Remote exploitation of the attack is possible. The attack's complexity is rated as high. The exploitability is reported as difficult. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
A vulnerability exists in liangliangyy DjangoBlog versions through 2.1.0.0, specifically within the file upload endpoint. The issue arises because the endpoint, located in blog/views.py, is exempt from CSRF protection and relies on a static HMAC signature derived from the SECRET_KEY for authentication. Since the SECRET_KEY contains a hard-coded fallback, the upload signature can be easily computed by anyone, allowing for unauthenticated arbitrary file uploads. Additionally, the ALLOWED_HOSTS setting is configured with a wildcard, disabling proper host header validation and potentially leading to injection attacks.
It is recommended to replace the static HMAC authentication with proper session-based authentication and to re-enable CSRF protection.
