Improper Authorization in danny-avila/librechat

In version 0.7.8 of danny-avila/librechat, improper authorization controls in the conversation sharing feature allow unauthorized access to other users' conversations if the conversation ID is known. Although UUIDv4 conversation IDs are generated server-side and are difficult to brute force, they can be obtained from less-protected sources such as server-side access logs, browser history, or screenshots. The vulnerability permits a logged-in user to gain read-only access to another user's conversations by exploiting the `/api/share/conversationID` endpoint, which lacks authorization checks. This issue is resolved in version v0.7.9-rc1.

LibreChat exposes arbitrary chats through Meilisearch engine

LibreChat is a ChatGPT clone with additional features. In versions 0.0.6 through 0.7.7-rc1, an exposed testing endpoint allows reading arbitrary chats directly from the Meilisearch engine. The endpoint /api/search/test allows for direct access to stored chats in the Meilisearch engine without proper access control. This results in the ability to read chats from arbitrary users. This issue is fixed in version 0.7.7.

A vulnerability in the Authentication, Authorization, and Accounting (AAA) feature of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to bypass command authorization and copy files to or from the file system of an affected device using the Secure Copy Protocol (SCP). This vulnerability is due to incorrect processing of SCP commands in AAA command authorization checks. An attacker with valid credentials and level 15 privileges could exploit this vulnerability by using SCP to connect to an affected device from an external machine. A successful exploit could allow the attacker to obtain or change the configuration of the affected device and put files on or retrieve files from the affected device.

Cisco SD-WAN vManage Software Authorization Bypass Vulnerability

A vulnerability in the web-based management interface of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to bypass authorization, enabling them to access sensitive information, modify the system configuration, or impact the availability of the affected system. The vulnerability is due to insufficient authorization checking on the affected system. An attacker could exploit this vulnerability by sending crafted HTTP requests to the web-based management interface of an affected system. A successful exploit could allow the attacker to gain privileges beyond what would normally be authorized for their configured user authorization level. The attacker may be able to access sensitive information, modify the system configuration, or impact the availability of the affected system.

OpenObserve Privilege Escalation Vulnerability in Users API

OpenObserve is a observability platform built specifically for logs, metrics, traces, analytics, designed to work at petabyte scale. A vulnerability has been identified in the "/api/{org_id}/users" endpoint. This vulnerability allows any authenticated regular user ('member') to add new users with elevated privileges, including the 'root' role, to an organization. This issue circumvents the intended security controls for role assignments. The vulnerability resides in the user creation process, where the payload does not validate the user roles. A regular user can manipulate the payload to assign root-level privileges. This vulnerability leads to Unauthorized Privilege Escalation and significantly compromises the application's role-based access control system. It allows unauthorized control over application resources and poses a risk to data security. All users, particularly those in administrative roles, are impacted. This issue has been addressed in release version 0.8.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.
