OWASP SKF CORS Misconfiguration

A Flask application (login admin/admin) whose /confidential page holds private data and answers cross-origin requests with credentials allowed.

Not startedDockercommit 596f3f4x86_64 · aarch64Secret

Objective

Read the logged-in victim's confidential data from a page on another origin by abusing the CORS policy.

The brief for this lab lives in its repository.

Submit evidenceSecret

Launch the lab

Open it in the Cyber CTF launcher, or run it yourself with Docker Compose.

Open in the launcher Source code

›Run it manually

$git clone https://github.com/CyberCTF/skf-cors && cd skf-cors && docker compose up -d

Without the launcher, the lab uses its public development evidence: great for practice, but it won't complete the lab.
