CVE-2026-81178: SysReptor: Anonymous note-share link discloses project member identities and non-shared note activity
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.

Frequently Asked Questions
Who can exploit this issue?
Any unauthenticated person who possesses a public note-share link can receive the exposed collaboration metadata. No project account is required, but user interaction is needed to open or use the shared link.
What information can be disclosed?
The exposed metadata can reveal project member usernames and names, identifiers of notes that were not shared, and live editing activity associated with those notes. It does not disclose the content of non-shared notes.
Does this allow an attacker to modify notes or other project data?
No. The issue does not grant write access; the impact is limited to disclosure of collaboration metadata.
What versions are affected and how should this be remediated?
SysReptor versions before 2026.55 are affected. Upgrade to version 2026.55 to apply the fix.
