Headline
GHSA-4269-mcfh-cp7q: Indico may disclose unauthorized user details access via legacy API
Impact
A legacy API to retrieve user details could be misused to retrieve profile details of other users without having admin permissions due to a broken access check.
Patches
You should to update to Indico 3.3.8 as soon as possible. See the docs for instructions on how to update.
Workarounds
It is possible to restrict access to the affected API (e.g. in the webserver config) which is most likely unused anyway and thus will not break anything.

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.
