- Severity: CVSS 2.3 (Low), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N

## Affected

- Openpanel-dev openpanel: through 2.3.0

## 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.
