Security readout for executives and security teams
Plain-English summary
CVE-2025-31592 is a stored cross-site scripting issue in the WordPress Send E-mail plugin through version 1.3. An attacker with low privileges could store malicious script content that runs when another user views the affected page. Business risk is moderate because exploitation requires privileges and user interaction, but successful abuse can affect trusted admin sessions.
Executive priority
Treat this as a scheduled but real remediation item for affected WordPress sites, especially where many users can access plugin functionality or administrators frequently review submitted content.
Technical view
The issue is CWE-79 improper input neutralization during web page generation in Paolo Melchiorre Send E-mail. The CVSS 3.1 score is 6.5 with network access, low attack complexity, low privileges, required user interaction, changed scope, and low confidentiality, integrity, and availability impact. Sources do not identify a fixed version or detailed remediation.
Likely exposure
Exposure is likely limited to WordPress sites with the Send E-mail plugin installed at version 1.3 or earlier. Sites without this plugin are not indicated as affected by the provided sources.
Exploitation context
The CVE is not listed as KEV in the provided bundle, and no cited source confirms active exploitation. The CVSS vector indicates an attacker needs low privileges and a victim interaction for impact.
Researcher notes
The source bundle identifies stored XSS but does not provide sink details, exploit prerequisites beyond CVSS, proof-of-concept status, or a fixed release. Avoid assuming affected routes or payload behavior without vendor or plugin-code confirmation.
Mitigation direction
- Inventory WordPress installations for the Send E-mail plugin and record installed versions.
- If version is 1.3 or older, check vendor or Patchstack guidance for a fixed version.
- Disable or remove the plugin where it is not business-critical.
- Restrict plugin access to trusted users until confirmed remediation is available.
- Monitor WordPress admin activity and stored content for suspicious script-like entries.
Validation and detection
- Confirm whether the Send E-mail plugin is installed on each WordPress site.
- Verify the installed plugin version against the affected range, through 1.3.
- Review user roles that can submit or manage plugin-controlled content.
- Check logs for unusual authenticated activity involving plugin pages or email-related content.
- Document whether a vendor-approved fixed version or compensating control is in place.
