Summit security scanner v0.5.0 and earlier versions contain a critical broken access control vulnerability in its authorization testing module. The flaw occurs due to improper role validation where high-privilege administrative endpoints and sensitive data (such as user salaries) are inadvertently served to low-privilege authenticated users without adequate authorization enforcement. Attackers can exploit this misconfiguration to bypass role-based access restrictions, harvest unauthorized records, and execute administrative functions directly within the application context.

What Undercode Say
Bash commands and codes related to the blog
git clone https://github.com/pennacle-security/summit.git cd summit pip install -e . summit authorize --target http://localhost:5000/admin --priv privileged_session --low low_session
Exploit: (Educational Purposes!)
The exploit leverages improper permission checks by replaying authenticated HTTP requests captured from a low-privilege user session against sensitive endpoints designated for administrators. Because the server fails to validate the underlying role claims against the requested URI resource, the application returns confidential payloads, confirming broken access control.
Protection: from this CVE
Ensure robust server-side role-based access control (RBAC) checks on every incoming request. Implement centralized authorization middleware that explicitly verifies user privileges against the requested resource route before dispatching any business logic or data serialization.
Impact:
Successful exploitation allows unprivileged users or malicious actors to access restricted administrative panels, view confidential financial or personal records, and compromise the overall confidentiality and integrity of the affected platform.
