Description

Impact

Event invitees created in topics in private categories or PMs (private messages) can be retrieved by anyone, even if they're not logged in.

Patches

This problem is resolved in the latest version of the discourse-calendar plugin

Workarounds

No real workaround.

Putting the site behind login_required will disallow this endpoint to be used by anonymous users, but logged in users can still get the list of invitees in the private topics.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
