Kyverno is a policy engine designed for Kubernetes. A kyverno ClusterPolicy, ie. "disallow-privileged-containers," can be overridden by the creation of a PolicyException in a random namespace. By design, PolicyExceptions are consumed from any namespace. Administrators may not recognize that this allows users with privileges to non-kyverno namespaces to create exceptions. This vulnerability is fixed in 1.13.0.

Waitress is a Web Server Gateway Interface server for Python 2 and 3. A remote client may send a request that is exactly recv_bytes (defaults to 8192) long, followed by a secondary request using HTTP pipelining. When request lookahead is disabled (default) we won't read any more requests, and when the first request fails due to a parsing error, we simply close the connection. However when request lookahead is enabled, it is possible to process and receive the first request, start sending the error message back to the client while we read the next request and queue it. This will allow the secondary request to be serviced by the worker thread while the connection should be closed. Waitress 3.0.1 fixes the race condition. As a workaround, disable channel_request_lookahead, this is set to 0 by default disabling this feature.

Scoold is a Q&A and a knowledge sharing platform for teams. A semicolon path injection vulnerability was found on the /api;/config endpoint. By appending a semicolon in the URL, attackers can bypass authentication and gain unauthorised access to sensitive configuration data. Furthermore, PUT requests on the /api;/config endpoint while setting the Content-Type: application/hocon header allow unauthenticated attackers to file reading via HOCON file inclusion. This allows attackers to retrieve sensitive information such as configuration files from the server, which can be leveraged for further exploitation. The vulnerability has been fixed in Scoold 1.64.0. A workaround would be to disable the Scoold API with scoold.api_enabled = false.

Waitress is a Web Server Gateway Interface server for Python 2 and 3. When a remote client closes the connection before waitress has had the opportunity to call getpeername() waitress won't correctly clean up the connection leading to the main thread attempting to write to a socket that no longer exists, but not removing it from the list of sockets to attempt to process. This leads to a busy-loop calling the write function. A remote attacker could run waitress out of available sockets with very little resources required. Waitress 3.0.1 contains fixes that remove the race condition.

An Open-Redirect vulnerability exists in PingAM where well-crafted requests may cause improper validation of redirect URLs. This could allow an attacker to redirect end-users to malicious sites under their control, simplifying phishing attacks

Organization admins can delete pending invites created in an organization they are not part of.

ServiceNow has addressed an input validation vulnerability that was identified in the Now Platform. This vulnerability could enable an unauthenticated user to remotely execute code within the context of the Now Platform. ServiceNow deployed an update to hosted instances and ServiceNow provided the update to our partners and self-hosted customers. Further, the vulnerability is addressed in the listed patches and hot fixes.

The FileOrganizer – Manage WordPress and Website Files plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the "fileorganizer_ajax_handler" function in all versions up to, and including, 1.0.9. This makes it possible for authenticated attackers, with Subscriber-level access and above, and permissions granted by an administrator, to upload arbitrary files on the affected site's server which may make remote code execution possible. NOTE: The FileOrganizer Pro plugin must be installed and active to allow Subscriber+ users to upload files.

A vulnerability in gaizhenbiao/chuanhuchatgpt version 20240628 allows for a Denial of Service (DOS) attack. When uploading a file, if an attacker appends a large number of characters to the end of a multipart boundary, the system will continuously process each character, rendering ChuanhuChatGPT inaccessible. This uncontrolled resource consumption can lead to prolonged unavailability of the service, disrupting operations and causing potential data inaccessibility and loss of productivity.

A vulnerability in the GraphCypherQAChain class of langchain-ai/langchain version 0.2.5 allows for SQL injection through prompt injection. This vulnerability can lead to unauthorized data manipulation, data exfiltration, denial of service (DoS) by deleting all data, breaches in multi-tenant security environments, and data integrity issues. Attackers can create, update, or delete nodes and relationships without proper authorization, extract sensitive data, disrupt services, access data across different tenants, and compromise the integrity of the database.
