Subscriber Server Side Request Forgery (SSRF) in FluentCRM Pro <= 3.1.12 versions.

Analysis

AI-generated

Technical impact

A server‑side request forgery flaw exists in WP ManageNinja LLC’s FluentCRM Pro plugin up to version 3.1.12. An attacker who can influence a subscriber entry can cause the plugin to issue HTTP requests to arbitrary URLs from the web server. This can lead to internal network enumeration or data exfiltration, but does not provide direct remote code execution. The weakness is identified as CWE‑918.

Affected Systems

WordPress sites running the FluentCRM Pro plugin version 3.1.12 or earlier, provided by WP ManageNinja LLC. All installations of the plugin with a version less than or equal to 3.1.12 are affected.

Risk and Exploitability

The CVSS score of 4.9 indicates moderate impact. EPSS data is not available, so there is no published estimate of exploitation probability, and the vulnerability is not listed in CISA’s KEV catalog. The likely attack vector is through crafted subscriber data that leads the plugin to fetch an attacker‑controlled address. Exploitation requires the ability to create or modify subscriber records, which may be restricted to users with sufficient permissions. The risk, while moderate, warrants timely remediation because SSRF can expose internal services if not mitigated.

Remediation

Vendor Solution

Update the WordPress FluentCRM Pro Plugin to the latest available version (at least 3.1.13).


OpenCVE Recommended Actions

  • Update the FluentCRM Pro plugin to version 3.1.13 or later.
  • If immediate update is not possible, disable subscriber creation functionality or restrict access to users until the patch is applied.
  • Configure the web application firewall or network firewall to block outbound requests from the WordPress instance to internal IP ranges and localhost addresses.
