vulnerability
A CSRF vulnerability in Facebook's Instagram Business Tools allowed attackers to execute arbitrary GraphQL mutations by crafting malicious URLs that leveraged the victim's authenticated access token, enabling unauthorized actions like creating posts with malicious content. The vulnerability exploited improper parameter handling in the /business/:id endpoint where user-controlled IDs were sent to the Graph API without proper CSRF protections.
