Technical details
The SVG exporter vulnerability involves improper handling of user-controlled fill-color values for text objects, which are passed to a ppmcolormask command via child_process.exec without proper sanitization. An authenticated user or anyone with access to a public share link can embed shell metacharacters in the fill color field; on SVG export, these are executed as shell commands with exporter service privileges. The fix replaces child_process.exec with execFile and adds strict hex color validation.
