Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

PinchTab versions before 0.7.7 are vulnerable to server-side request forgery through the /download endpoint, whose url parameter is passed to the headless browser without validation. An attacker with API access can make the server fetch local files, internal services, or cloud metadata endpoints and receive the full response body. Upgrade to PinchTab 0.7.7 or later.
