Security readout for executives and security teams
Plain-English summary
This affects WordPress sites using Kiboko Labs Arigato Autoresponder and Newsletter up to 2.7.1.1. An unauthenticated attacker may store malicious script that runs when another user interacts with affected content. That can expose user data, alter page behavior, or disrupt trust in the site.
Executive priority
Treat this as a high-priority WordPress plugin exposure review. It is not confirmed as actively exploited in the supplied sources, but unauthenticated stored XSS on public sites can create reputational, account, and data-risk consequences.
Technical view
CVE-2023-25020 is an unauthenticated stored XSS in the WordPress plugin bft-autoresponder, mapped to CWE-79. CVSS 3.1 is 7.1 with network access, low complexity, no privileges, required user interaction, changed scope, and low confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to WordPress installations running Arigato Autoresponder and Newsletter versions 2.7.1.1 or earlier. Public-facing WordPress sites are the primary concern, especially where newsletter or autoresponder functions accept unauthenticated input.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation evidence. The vulnerability is still business-relevant because stored XSS can persist until removed and may affect administrators or visitors who view the affected content.
Researcher notes
Evidence is limited to the CVE record and Patchstack reference. The bundle does not include a fixed version, exploit proof, or detailed vulnerable parameter information, so validation should stay version- and exposure-based unless official vendor details are available.
Mitigation direction
- Inventory WordPress sites for Arigato Autoresponder and Newsletter plugin use.
- Check vendor or Patchstack guidance for a fixed version or official workaround.
- If no fix is available, disable or remove the plugin where feasible.
- Prioritize public-facing sites and administrator-accessible affected content.
- Review stored newsletter or autoresponder content for unexpected script-like content.
Validation and detection
- Confirm plugin slug bft-autoresponder and installed version across WordPress assets.
- Flag installations running version 2.7.1.1 or earlier.
- Check whether unauthenticated users can submit affected newsletter or autoresponder content.
- Review site logs and content records for suspicious submissions around vulnerable workflows.
- Verify remediation by confirming the plugin is updated, disabled, or removed.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
