Projectsend version r1295 is affected by a directory traversal vulnerability.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.37%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Projectsend version r1295 is affected by a directory traversal vulnerability. Because of lacking sanitization input for files[] parameter, an attacker can add ../ to move all PHP files or any file on the system that has permissions to /upload/files/ folder.
