CVE-2026-108579 · Severity: medium · CVSS 4.2 · Published 2026-10-10

OpenPanel is an open-source analytics platform that tracks user events and generates reports. An unauthenticated attacker can inject spreadsheet formulas into exported CSV reports by supplying specially crafted profile IDs, allowing formulas like =HYPERLINK() to execute when opened in a spreadsheet application and potentially exfiltrate adjacent data.

## 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.
