Security readout for executives and security teams
Plain-English summary
CVE-2022-46803 affects the WordPress Noptin newsletter plugin through version 1.9.5. An outside user may be able to place spreadsheet formulas into data that later appears in CSV exports. The business risk is mainly to staff who open exported subscriber data in spreadsheet software.
Executive priority
Handle as a moderate-priority WordPress plugin issue. It is not shown as actively exploited, but it can affect staff workflows and data integrity when CSV exports are opened.
Technical view
The issue is CWE-1236, improper neutralization of formula elements in CSV output. The CVSS 3.1 score is 6.1 medium with network access, no privileges, required user interaction, changed scope, and high integrity impact. Provided sources identify the affected package as newsletter-optin-box through 1.9.5.
Likely exposure
Exposure is likely limited to WordPress sites using Simple Newsletter Plugin - Noptin at version 1.9.5 or earlier, especially where administrators export CSV subscriber or form data.
Exploitation context
The provided bundle does not show CISA KEV listing or evidence of active exploitation. Risk depends on attacker-controlled data entering exports and a staff member opening the CSV in spreadsheet software.
Researcher notes
Evidence is narrow but consistent: CVE and Patchstack identify CSV injection in Noptin through 1.9.5. Avoid assuming a specific fixed version from the bundle alone; validate against current vendor or Patchstack records.
Mitigation direction
- Identify WordPress sites running Noptin newsletter plugin.
- Confirm whether installed versions are 1.9.5 or earlier.
- Check Noptin or Patchstack guidance for a fixed release.
- Update, disable, or remove the plugin if no safe version is available.
- Treat exported CSV files as untrusted until remediation is confirmed.
Validation and detection
- Inventory WordPress plugins for package newsletter-optin-box.
- Review plugin version evidence from WordPress admin or asset records.
- Check whether CSV export workflows are used by staff.
- Confirm remediation against vendor or Patchstack guidance.
- Verify staff handling procedures for exported CSV files.

Improper Neutralization of Formula Elements in a CSV File
Improper Neutralization of Formula Elements in a CSV File represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
