CVE-2026-108579 Details
Description
OpenPanel through 2.3.0 contains a CSV formula injection vulnerability that allows unauthenticated attackers to embed spreadsheet formulas by supplying crafted profile IDs to the /track endpoint. Attackers can send tracking events with profile IDs like =HYPERLINK(...) matching a cohort, so exported cohort CSVs execute formulas that exfiltrate adjacent cell data.
A CSV formula injection vulnerability has been identified in OpenPanel versions through 2.3.0. This vulnerability allows unauthenticated attackers to inject spreadsheet formulas by sending crafted profile IDs to the /track endpoint. The injected formulas can be executed when cohort data is exported to CSV, potentially leading to unauthorized data exfiltration.
The vulnerability can be addressed by modifying the CSV export function to neutralize leading characters that indicate a formula, such as '=', '+', '-', and '@'. This can be done by prefixing a single quote to any profile ID that starts with these characters before the CSV is exported.
