Technical details
The vulnerability is a CSV formula injection (CWE-1236) in the /track endpoint's cohort export functionality. The escapeCsvValue() function fails to sanitize profile IDs that begin with formula indicators (=, +, -, @), allowing unauthenticated attackers to inject formulas that execute when the CSV is opened in a spreadsheet application. An attacker can send tracking events with crafted profile IDs matching a cohort, and when cohort members are exported to CSV, the formulas execute.
