# Bahleel: CSV export lets remote input inject spreadsheet formulas

Link for people: https://infrastack.ai/live/CVE-2026-124591 (this .md is for agents)

Bahleel 0.1.0 and 0.1.1 write user-supplied values into CSV exports without neutralizing them, in the fputcsv call in app/Exporters/CsvExporter.php. An attacker can plant spreadsheet formulas that run when a victim opens the exported file.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Look for `app/Exporters/CsvExporter.php` in the Bahleel install and check whether it calls `fputcsv` on unsanitized data.
- Check the installed Bahleel version against `0.1.0` and `0.1.1`.
