Title

Snipe-IT: CSV formula injection in Activity Report export

Summary

Snipe-IT is an IT asset/license management system. Prior to 8.5.0, Actionlog::logaction() stores the request User-Agent header and ReportsController::postActivityReport() writes that value to the Activity Report CSV without formula escaping, allowing a low-privileged authenticated user to store a formula-like User-Agent that may execute when a report viewer opens the exported CSV in spreadsheet software. This issue is fixed in version 8.5.0.

Severity

4.8 (Medium)

Vulnerability from github – Published: 2026-08-28 17:46 – Updated: 2026-08-28 17:46

Summary

Snipe-IT has CSV formula injection in Activity Report export

Details

Impact

In Snipe-IT v8.6.1 and lower, Actionlog::logaction() stores the request User-Agent header in user_agent. That value is later included in the Activity Report CSV export by ReportsController::postActivityReport() and written with plain fputcsv().

A low-privileged authenticated user can set a formula-like User-Agent, perform a logged action, and have that value stored in the activity log. If an admin or report viewer later exports the Activity Report and opens it in spreadsheet software, the formula may execute.

Example payload:

User-Agent: =HYPERLINK("https://example.com/","click")

Severity

4.8 (Medium)
