Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

FacturaScripts versions from 2025 before 2026.3 do not sanitize uploaded file names, so an authenticated user with upload permission can write files outside the MyFiles/ directory. The source describes chaining this to remote code execution as the web server user. Upgrade to FacturaScripts 2026.3, which fixes the issue.
