CVE-2022-1386
Published: 16 May 2022
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 0.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
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.
