Poster Discovers Vulnerability and Gains Admin Access to E-commerce Site

The poster discovered a vulnerability in an e-commerce website while testing it without malicious intent, which granted them full administrative access. They now have control over the site, including access to its code, customer data, supplier information, sales, orders, and product listings. The website reportedly generates $500,000 in revenue. The poster is unsure whether to contact the site owners or request payment for disclosing the vulnerability.
