Grafana is an open-source platform for monitoring and observability. The option to send a test alert is not available from the user panel UI for users having the Viewer role. It is still possible for a user with the Viewer role to send a test alert using the API as the API does not check access to this function. This might enable malicious users to abuse the functionality by sending multiple alert messages to e-mail and Slack, spamming users, prepare Phishing attack or block SMTP server. Users may upgrade to version 9.5.3, 9.4.12, 9.3.15, 9.2.19 and 8.5.26 to receive a fix.

This vulnerability exists in the DELETE /api/org/users/ endpoint. The vulnerability can be exploited when: 1. An Organization administrator exists 2. The Server administrator is either: - Not part of any organization, or - Part of the same organization as the Organization administrator Impact: - Organization administrators can permanently delete Server administrator accounts - If the only Server administrator is deleted, the Grafana instance becomes unmanageable - No super-user permissions remain in the system - Affects all users, organizations, and teams managed in the instance The vulnerability is particularly serious as it can lead to a complete loss of administrative control over the Grafana instance.

SiYuan Note publish service authorization bypass allows low-privilege users to modify notebook content

SiYuan is a personal knowledge management system. Prior to 3.5.10, a privilege escalation vulnerability exists in the publish service of SiYuan Note that allows low-privilege publish accounts (RoleReader) to modify notebook content via the /api/block/appendHeadingChildren API endpoint. The endpoint requires only the model.CheckAuth role, which accepts RoleReader sessions, but it does not enforce stricter checks, such as CheckAdminRole or CheckReadonly. This allows remote authenticated publish users with read-only privileges to append new blocks to existing documents, compromising the integrity of stored notes.
