Vulnerability Description
Joomla Extension - joomshaper.com - Missing Directory Confinement in Media Upload in SP Page Builder (Free and Pro) 4.0.0 - 6.9.0 - The folder request parameter replaced the generated date-based destination folder in its entirety and was then passed to Folder::create() and File::upload() without either of the directory boundary checks applied elsewhere in the same file. Files could be written into any directory beneath the web root, including administrator/, templates/, cli/ and the site root. Joomla's PATH input filter prevented traversal above the web root, and existing files were not overwritten.
