The theme editor in Bolt before 2.2.5 does not check the file extension when renaming files, which allows remote authenticated users to execute arbitrary code by renaming a crafted file and then directly accessing it.
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
