Details

A vulnerability in the REST API of Cisco Slido could have allowed an authenticated, remote attacker to access the social profile data of other users or affect quiz and poll results. Cisco has addressed this vulnerability in Cisco Slido and no customer action is needed.

This vulnerability existed because of the presence of an insecure direct object reference. Prior to this vulnerability being addressed, an attacker could have exploited this vulnerability by sending a crafted request to the vulnerable API endpoint. A successful exploit could have allowed the attacker to view the social profiles of other users or affect quiz and poll results.

Vulnerability from github – Published: 2026-07-21 21:32 – Updated: 2026-07-21 21:32
VLAI
Details

Authorization Bypass Through User-Controlled Key (CWE-639) in Kibana can lead to unauthorized information disclosure and case attachment integrity compromise via Privilege Abuse (CAPEC-122). An inconsistency in Kibana's file access authorization logic allows a low-privileged authenticated user to retrieve, modify, and delete case attachments that belong to feature areas they are not authorized to access. Because the access control check and the resource retrieval use different resolution mechanisms, an authenticated attacker with limited file management permissions can obtain the contents of, modify, or delete protected case attachments — such as those associated with Security Solution cases — without holding the privileges required to access those features.

Mitigation
Architecture and Design

For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.

Mitigation
Architecture and Design Implementation

Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.

Mitigation
Architecture and Design

Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
