Security Vulnerabilities
A stack-based buffer overflow in the export_language.cgi binary in VIVOTEK FD8136 firmware FD8136-VVTK-0300a allows authenticated remote attackers to execute arbitrary code as root via a crafted POST request to the /cgi-bin/admin/export_language.cgi endpoint. The handler passes the attacker-controlled Content-Length value directly to fread() as the read size into a fixed-size 0x60-byte stack buffer, overwriting the saved link register. The binary is compiled without stack canaries.

An improper authorization vulnerability has been identified in Apache Kafka.
The implementation of the CONSUMER_GROUP_DESCRIBE (69) API validates the DESCRIBE operation on the GROUP resource instead of the READ operation that documented in the official kafka documentation and the KIP-848. This discrepancy can result in misconfigured Access Control Lists (ACLs) and unintended security postures, like granting READ permission to users who should not be able to join/sync groups, or allowing users without READ permission (but with DESCRIBE permission) to access sensitive group metadata.
The correct permission for CONSUMER_GROUP_DESCRIBE API is DESCRIBE GROUP so the current implementation is correct. However, the kafka documentation as well as the KIP-848 will be updated to reflect the correct permission. We advise the Kafka users to review existing group ACLs to ensure the principle of least privilege.

A path traversal vulnerability exists in jupyter-server version 2.17.0 due to an incorrect root directory boundary check in the _get_os_path() function within jupyter_server/services/contents/fileio.py. The check uses startswith(root) without appending a trailing path separator, allowing sibling directories with names starting with the same prefix as root_dir to bypass the check. Additionally, the to_os_path() function in utils.py does not strip ".." from path parts, enabling traversal sequences to bypass the vulnerable check. This vulnerability can lead to unauthorized read/write access to files in sibling directories, potentially exposing sensitive data in shared hosting environments.

In version 3.6.19 of prefecthq/prefect, an authentication bypass vulnerability exists due to the improper handling of URL path exemptions for health check probes. Specifically, the authentication middleware exempts any URL path ending with 'health' or 'ready' from authentication checks. This allows an attacker to create resources with names ending in 'health' or 'ready' and access them without authentication. Affected endpoints include those for variables, flows, work pools, work queues, and deployments. This vulnerability can lead to unauthorized access to sensitive information, such as API keys and database credentials, stored in Prefect Variables.

MLflow 3.9.0 with basic-auth (`--app-name basic-auth`) fails to enforce authorization checks for multiple Gateway API 'list' endpoints. Specifically, the `BEFORE_REQUEST_HANDLERS` dictionary in `mlflow/server/auth/__init__.py` does not include entries for `ListGatewaySecretInfos`, `ListGatewayEndpoints`, and `ListGatewayModelDefinitions`. This allows any authenticated user, regardless of their assigned permissions, to enumerate all gateway secrets, endpoints, and model definitions. This vulnerability exposes sensitive information, such as API keys, endpoint configurations, and proprietary model definitions, to unauthorized users.

eLabFTW is an open source electronic lab notebook. Prior to version 5.4.2, in certain cases, an authenticated user performing a numeric reference/search can return results that include resources the requesting user is not authorized to view. The exposed information is limited (only the title). Attempts to access the underlying protected resource content remain blocked by authorization checks. Version 5.4.2 fixes the issue.
# Affected Scope
Cross-scope visibility of titles.
No confirmed bypass of content-level access controls
# Preconditions
An authenticated user account
No special privileges required beyond standard access
# Impact
This may enable unauthorized disclosure of sensitive information if confidential data is included in resource titles. Examples could include project names, patient identifiers, or other regulated information embedded in titles.

Kiteworks is a private data network (PDN). Prior to version 9.3.0,ultiple SQL Injection vulnerabilities in Kiteworks Secure Data Forms could be exploited by an authenticated attacker with the FormBuilder role to retrieve information on or modify other users' form definitions and some global configuration parameters. Upgrade Kiteworks to version 9.3.0 or later to receive a patch.
