This makes it possible for unauthenticated attackers to modify JetEngine Options Page values when an administrator has configured a form with the \"Update Options\" post-submission action. The vulnerability requires that both JetFormBuilder and JetEngine are installed and active, and that an administrator has specifically configured a form with the Update Options action.\n\n## Affected\n\n- `jetformbuilder_dynamic_blocks_form_builder <= 3.6.2`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
