Summary

SysReptor is a fully customizable pentest reporting platform. Prior to 2026.68, an unauthenticated attacker who holds a public read-write note share link can disclose an uploaded file or image from the same project by updating the shared note to reference the target asset filename. The user-controlled reference causes the shared-note authorization logic to treat the asset as permitted, after which the attacker can download it. The attacker must know the asset filename, and the issue does not permit cross-project access. This issue is fixed in version 2026.68.
