CVE-2026-55452: CWE-1236: Improper Neutralization of Formula Elements in a CSV File in grokability snipe-it
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.
AI Analysis
Technical Summary
The vulnerability in Snipe-IT (CVE-2026-55452) involves improper neutralization of formula elements (CWE-1236) in CSV exports. Specifically, the Actionlog::logaction() function stores the User-Agent header from HTTP requests, and the ReportsController::postActivityReport() writes this value directly into the Activity Report CSV without escaping formulas. This can lead to formula injection attacks when a report viewer opens the CSV in spreadsheet software. The vulnerability affects all versions prior to 8.5.0 and has a CVSS 4.8 (medium) severity score. No known exploits are reported in the wild. The issue is resolved in version 8.5.0.
Potential Impact
A low-privileged authenticated user can inject malicious formula content into CSV reports via the User-Agent header. When a user opens the exported CSV in spreadsheet software, the formula may execute, potentially leading to unintended actions or data exposure. The impact is limited by the need for authentication and user interaction to open the CSV file.
Mitigation Recommendations
Upgrade Snipe-IT to version 8.5.0 or later, where this vulnerability is fixed by proper formula escaping in CSV exports. No other official remediation or temporary fixes are documented. Users should avoid opening CSV reports from untrusted sources or with untrusted content until upgraded.
