Summary

CVE-2022-1386 is a critical-severity SSRF (CWE-918) vulnerability in Fusion Builder Project Fusion Builder. Its CVSS base score is 9.8 (Critical).

Operationally, ranked in the top 0.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-4 (Information Flow Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The Fusion Builder WordPress plugin before version 3.6.2, a component of the Avada theme, contains a server-side request forgery vulnerability (CWE-918). The plugin fails to validate a parameter within its forms, allowing arbitrary HTTP requests to be initiated from the server; responses from those requests are then reflected in the application output.

Unauthenticated remote attackers can exploit the flaw over the network without user interaction to reach internal hosts that would otherwise be protected by firewalls or network segmentation. Successful exploitation can result in disclosure of sensitive information, modification of data, or disruption of services, consistent with the CVSS 9.8 rating.

Public advisories from ThemeFusion and WPScan indicate that the issue is resolved in Avada 7.6.2 (which bundles Fusion Builder 3.6.2); site owners are advised to apply the update promptly. The associated EPSS score has remained at a sustained high of 0.9361 with no material post-disclosure increase reported.

Vulnerability Data

The Fusion Builder WordPress plugin before 3.6.2, used in the Avada theme, does not validate a parameter in its forms which could be used to initiate arbitrary HTTP requests. The data returned is then reflected back in the application's response.…

This could be used to interact with hosts on the server's local network bypassing firewalls and access control measures.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation of all inputs to the Fusion Builder forms, blocking the unvalidated parameter that enables arbitrary SSRF requests.

prevent

Enforces information-flow policies that would deny the plugin's server-initiated HTTP requests to internal hosts otherwise protected by network segmentation.

prevent

Boundary-protection mechanisms (e.g., deny-by-default egress rules or proxy enforcement) limit the plugin's ability to reach internal hosts even if input validation fails.
