CVE-2022-1539Public exploitNetwork attack vector

Contributor-level spreadsheet formula execution via unsanitized export

Published Jul 25, 2022 · Updated Aug 3, 2024

CSV injection in Exports and Reports before 0.9.2 allows remote authenticated users to trigger spreadsheet formulas through exported data. The CSV generator writes contributor-controlled post titles without neutralizing leading formula characters, so Excel or OpenOffice interprets payloads as formulas or hyperlinks. Contributor access is sufficient to plant a payload, but an administrator must export the affected data and open the CSV in a spreadsheet; execution or data disclosure then occurs in that user's context.
