Description

Missing token audience validation in the OAuth authentication mode of AWS API MCP Server before version 1.6.0 might allow local users to run AWS operations with the server's configured AWS credentials via an access token issued to another application by the same identity provider. To remediate this issue, users should upgrade to version 1.6.0 and configure the expected token audience or client ID for the server.

CVE-2026-116690
MLflow is an open source AI engineering platform for agents, large language models, and machine learning models. From 3.10.0 until 3.17.0, the prompt branch in _create_model_version() accepts schemeless relative sources because path validation runs only when a source has a URL scheme, and mlflow.prompt.is_prompt is interpreted by tag presence rather than a true value. A remote caller can store a server-local path as the model version artifact location and use /api/2.0/mlflow/model-versions/get-artifact to read files accessible to the MLflow server process. Default unauthenticated servers require no privileges, while basic-auth deployments are exposed to authenticated users who can create registered models. This issue is fixed in version 3.17.0.

CVE-2026-116688
CKEditor 5 is a modern JavaScript rich-text editor with an MVC architecture. From 45.0.0 until 47.7.4 and 48.5.1, the engine uses a vulnerable es-toolkit version whose prototype-pollution behavior can be reached while CKEditor processes incoming style attribute values. Crafted editor content can thereby cause unauthorized JavaScript execution in the browser. This issue is fixed in versions 47.7.4 and 48.5.1.

CVE-2026-112355
The MembershipWorks plugin for WordPress before 6.17 contains an information disclosure vulnerability that allows unauthenticated attackers to access member-only content through the WordPress REST API. Because the filter that strips protected content for non-members is only attached during normal front-end request handling and not during REST API requests, an unauthenticated attacker can retrieve the raw member-only content in a post or page’s rendered content, bypassing the plugin’s content protection.

CVE-2026-112351
Sunhillo SureLine before 9.1.5 contains an OS command injection vulnerability in the networkDiag.cgi endpoint that allows an authenticated remote attacker with any web account to execute arbitrary commands as root by injecting shell metacharacters into the ipAddr or dnsAddr parameters. Attackers can bypass the incomplete character denylist from the prior CVE-2021-36380 fix using URL-encoded newline (%0a) or ampersand (%26) sequences that act as command separators after decoding in the ping, nslookup, or traceroute diagnostic modes, leading to full system compromise.

CVE-2026-112350
Sunhillo SureLine before 9.1.5 contains a path traversal vulnerability in the radarUpdater.cgi endpoint that allows unauthenticated remote attackers to read arbitrary files with root privileges due to missing authentication checks and insufficient sanitization of the filename parameter. Attackers can use directory traversal sequences to access sensitive files such as /etc/shadow, the web user database, the root SSH private key, and the device's TLS private key, leading to full system compromise.
