CVE-2026-76801: FireBox permits author-level code execution through PHP condition rules

FireBox through 3.1.10 stores unsanitized PHP condition-rule values through the firebox_meta REST endpoint. When the value function evaluates them, the regex blacklist in Executer::allowedToRun() fails to prevent dangerous function calls, allowing server-side code execution. On sites upgraded from a version before 3.1.10, Migrator::preserveCampaignRoleAccess() grants Authors edit_fireboxes and publish_fireboxes, making those Author accounts able to reach the vulnerable functionality.
