SysReptor is a fully customizable pentest reporting platform. Prior to 2026.55, an unauthenticated holder of a public note share link receives project-wide collaborative editing metadata because the public share consumer joins the same collaboration group as authenticated project members and forwards client information, connection, awareness, and deletion events without consistently restricting them to the shared note subtree. The disclosed metadata can identify project members through usernames and names and reveal the identifiers and live editing activity of notes that were not shared. The content of non-shared notes remains protected, and the issue does not grant write access. This issue is fixed in version 2026.55.
