CVE-2022-2352: Post SMTP < 2.1.7 - Admin+ Blind SSRF

The Post SMTP Mailer/Email Log WordPress plugin before 2.1.7 does not have proper authorisation in some AJAX actions, which could allow high privilege users such as admin to perform blind SSRF on multisite installations for example.

Security readout for executives and security teams

Plain-English summary

This WordPress plugin flaw lets an already high-privileged user abuse insufficient AJAX authorization to make the server send blind requests. The practical risk is highest on multisite WordPress environments where site administrators are not fully trusted. The bundle does not show active exploitation.

Executive priority

Treat this as a high-priority hygiene fix for WordPress multisite or shared-admin environments. It is not shown as actively exploited, but SSRF can expose sensitive internal services if the server has broad network reach.

Technical view

CVE-2022-2352 is a CWE-918 blind SSRF issue in Post SMTP Mailer/Email Log before 2.1.7. Some AJAX actions lack proper authorization, enabling high-privilege users such as admins to trigger server-side requests. CVSS 3.1 is 7.2 with PR:H and no user interaction.

Likely exposure

Exposure is likely limited to WordPress sites running Post SMTP Mailer/Email Log before 2.1.7. Multisite deployments with delegated or semi-trusted administrators are the main concern. Single-site environments with tightly trusted admins have lower practical exposure, but should still update.

Exploitation context

The source bundle and KEV status do not confirm active exploitation. The vulnerability requires high privileges, but SSRF can matter because the WordPress server may reach internal services, metadata endpoints, or restricted network locations unavailable to the user directly.

Researcher notes

Evidence is limited to the CVE description and WPScan reference. The bundle does not name specific AJAX action identifiers, proof-of-concept details, or observed exploitation. Validate exposure by version and deployment model rather than assuming internet-wide exploitability.

Mitigation direction

  • Update Post SMTP Mailer/Email Log to 2.1.7 or later.
  • Review vendor guidance for any additional recommended remediation.
  • Limit WordPress administrator access to trusted users only.
  • Restrict server egress to internal or sensitive network destinations where feasible.
  • Prioritize multisite environments with delegated admin roles.

Validation and detection

  • Inventory WordPress sites using Post SMTP Mailer/Email Log.
  • Confirm installed plugin versions are not older than 2.1.7.
  • Identify whether affected sites run WordPress multisite.
  • Review administrator accounts for unnecessary or shared access.
  • Check logs for unusual admin AJAX activity or unexpected server-side requests.
