CVE-2025-10741Public exploitNetwork attack vector

Arbitrary file upload via trusted MIME type

Published Sep 20, 2025 · Updated Sep 22, 2025

Unrestricted file upload in Selleo Mentingo 2025.08.0 through 2025.08.27 allows remote authenticated users to store arbitrary files. The profile and course-image handlers trust the multipart Content-Type header without checking file signatures, contents, or filename extensions. Student-level access is sufficient; spoofing an allowed MIME type stores attacker-controlled content in S3 or MinIO, enabling storage abuse and stored XSS when a victim opens a malicious SVG.
