Technical details
The vulnerability exists in Frappe's file-upload handling code, which fails to validate and sanitize the destination path before writing files to disk (CWE-22). An authenticated attacker with network access can exploit this by uploading a crafted file with path traversal sequences (e.g., ../) to write executable code to arbitrary locations, achieving remote code execution. The attack requires only low-level authentication and no user interaction.
