Scope changes to the victim's spreadsheet application where HYPERLINK/WEBSERVICE achieves high confidentiality impact; low privilege required, user interaction mandatory, no availability impact on Snipe-IT itself.

Lifecycle Timeline
3DescriptionCVE.org
Snipe-IT through 8.6.3 does not neutralize formula elements in the "unaccepted assets" acceptance report CSV export. ReportsController::postAssetAcceptanceReport builds the CSV by hand (stripping commas and joining rows manually) and, unlike the six sibling exports in the same controller, never applies League\Csv\EscapeFormula or honors the config('app.escape_formulas') setting. An authenticated low-privilege user with ordinary create/edit rights on any record whose free-text fields appear in the report (asset name/tag, company name, category, model, or assignee display name) can set such a field to a value beginning with =, +, -, @, tab, or CR. When a user with reports.view privileges requests the export (POST /reports/unaccepted_assets) for a pending checkout acceptance referencing the poisoned record and opens the resulting CSV in Excel, LibreOffice Calc, or Google Sheets, the injected content is evaluated as a formula in the downloader's spreadsheet context, enabling data exfiltration (e.g., HYPERLINK/WEBSERVICE) or, on legacy Windows Excel configurations, DDE command execution. Fixed in 8.7.0.
AnalysisAI
CSV formula injection in Snipe-IT through 8.6.3 allows authenticated low-privilege users to plant spreadsheet formulas in the unaccepted assets acceptance report export, which execute in the spreadsheet client of any privileged user who downloads and opens the file. The ReportsController::postAssetAcceptanceReport method builds its CSV output by hand without applying the League\Csv\EscapeFormula sanitizer already wired into the six sibling exports in the same controller, permitting injection of =, +, -, @, tab, or CR-prefixed values into free-text fields such as asset name, company name, category, model, or assignee. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must hold a valid Snipe-IT account with create or edit rights over at least one record whose free-text fields appear in the unaccepted assets report: asset name, asset tag, company name, category, model name, or assignee display name. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 5.1 Medium accurately reflects the two-party delivery requirement - the low-privilege attacker cannot self-trigger the formula; a second user holding reports.view access must download and open the CSV. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade Snipe-IT to version 8.7.0 or later, which applies League\Csv\EscapeFormula with a backtick prefix to all user-controlled data rows in the affected report export, consistent with the existing pattern used by six other exports in the controller. … Detailed patch versions, workarounds, and compensating controls in full report. |
