Contributor Privilege Escalation in Fusion Builder <= 3.15.4 versions.
AnalysisAI
Privilege escalation in the Fusion Builder WordPress plugin (versions 3.15.4 and earlier) lets a low-privileged authenticated user, such as a Contributor, gain capabilities far beyond their role and effectively act as an administrator. The flaw was reported by Patchstack and carries a CVSS 8.8; no public exploit identified at time of analysis and it is not listed in CISA KEV. Because Fusion Builder is the page builder bundled with the widely sold Avada theme, the exposure spans a large number of WordPress sites that allow self-registration or untrusted contributor accounts.
