Maya Chen, lead backend engineer at Artify, stared at the integration dashboard. The green line pulsed steadily: 2.3 million account links between Artify and CordChat in the last 48 hours. Their new SDK—dubbed "Canvas"—was a success. Users could now create a meme in Artify, hit a slash command /publish , and watch it render instantly inside a CordChat server, complete with layers, animation metadata, and revision history.
The bug was buried in the account linking handshake—specifically, the scope parameter. When a user clicked “Connect Artify to CordChat,” the SDK requested read:public and write:canvases .

No unauthorized access occurred beyond cached thumbnails. We have rotated your credentials.” Users could now create a meme in Artify,
Maya pulled up the account linking audit trail. Each row showed a pair of IDs: artify_user_id <> cordchat_user_id . For 1,240 accounts, the SDK had silently elevated privileges.
Maya nodded. “Next version. We call it ‘Per-Canvas Permissions.’ And we deprecate the old handshake entirely.”
The press, however, got a different version. Artify’s CTO published a post-mortem titled “On Scope and Trust: Lessons from the Canvas SDK Handshake.” It became required reading for every developer using their API.
