7.1CVE-2026-70485: Server-Side Request Forgery in Open WebUI via NAT64 IP Wrapping Bypass
Open WebUI is susceptible to Server-Side Request Forgery (SSRF) when deployed in networks with NAT64 translation gateways. Authenticated users can bypass host validation checks by encapsulating internal or cloud-metadata IPv4 addresses within globally-routable IPv6 transition prefixes.

7.6CVE-2026-70474: Incorrect Authorization and Missing Authentication in Flowise OAuth2 Credential Endpoints
A critical authorization flaw exists in Flowise, a popular drag-and-drop orchestrator for building customized Large Language Model flows. Prior to version 3.1.3, multiple OAuth2 credential endpoints do not filter database lookups by the requesting entity's workspace context. This omission, combined with the exclusion of several endpoints from the global authentication pipeline, permits unauthenticated remote actors to access, manipulate, or steal access tokens linked to external service integrations.

7.1CVE-2026-69262: Incorrect Authorization Flaw in Flowise Chatflow Deletion Endpoint
CVE-2026-69262 is a high-severity incorrect authorization vulnerability (CWE-863) within the Flowise drag-and-drop LLM flow platform. Prior to version 3.1.3, Flowise did not enforce resource-type validation on its deletion endpoint. Although routing middleware ensured users held deletion privileges for either chatflows or agentflows, the service level lacked validation checks to verify whether the target resource matched the user's specific permissions. Consequently, an authenticated user with only agentflow deletion permissions could delete arbitrary chatflow configurations, leading to unauthorized state modification and service disruption.

8.8CVE-2026-69258: Unauthenticated Property Injection and Authorization Bypass in Flowise
CVE-2026-69258 is a high-severity property injection and unauthenticated authorization bypass vulnerability in Flowise, a drag-and-drop orchestration interface for building customized LLM workflows. In affected versions prior to 3.1.3, the unauthenticated prediction API endpoint (`POST /api/v1/prediction/:id`) processed client-controlled parameters inside an `overrideConfig` payload without authorization checks. The backend unconditionally spread this object into internal context structures, enabling unauthenticated remote attackers to overwrite critical session values, pollute execution contexts, and bypass flow restrictions.

7.2CVE-2026-69252: Broken Workspace Isolation and Missing Authorization in Flowise File Management API
CVE-2026-69252 represents a missing authorization check (CWE-862) in the files API route (`/api/v1/files`) of Flowise, a drag-and-drop user interface for building LLM flows. Prior to version 3.1.3, an authenticated API key or user could list, access, and delete files across arbitrary workspaces inside an organization, completely bypassing workspace logical boundaries.

4.8CVE-2026-16728: Downstream HTTP Response Desynchronization in Undici Retry Interceptor
A medium-severity vulnerability in Undici's retry interceptor causes body-length mismatches with the Content-Length header during HTTP 206 response resumption. Forwarding these inconsistent headers downstream leads to HTTP response desynchronization, connection hangs, or potential protocol smuggling.

4.8CVE-2026-16729: Cookie Attribute Injection in Undici via Unsanitized Domain and Unparsed Fields
CVE-2026-16729 (GHSA-v3r7-h72x-cjcm) is a medium-severity cookie attribute injection vulnerability in Undici's web-compliant cookie utility module. Due to insufficient validation of domain parameters and raw attributes in the unparsed options array, arbitrary attributes like SameSite, HttpOnly, and Secure can be injected. This allows attackers to bypass CSRF protections, strip security flags, or override intended cookie behaviors when applications pass user-controlled values to these properties.

An interpretation conflict (CWE-436) in the cache interceptor of the undici HTTP client for Node.js causes whitespace-padded Cache-Control directives to be parsed incorrectly, leading to shared cache pollution and the unauthorized disclosure of sensitive, private, or authenticated user information (CWE-524).

4.2CVE-2026-15157: CRLF Injection in undici HTTP/1.1 Dispatcher
CVE-2026-15157 details an improper neutralization of CRLF sequences ('CRLF Injection') within undici, a widely used Node.js HTTP/1.1 client. The vulnerability is triggered when processing request bodies that exhibit a duck-typed blob-like interface. When an application accepts untrusted data and assigns it to the .type property of such an object without setting an explicit Content-Type on the request, undici appends the value directly to the outgoing headers array without validating it against control characters. This allows remote attackers to inject carriage return and line feed sequences, culminating in arbitrary header injection, HTTP response splitting, or HTTP request smuggling.

6.9CVE-2026-54272: SSRF and Trust-Boundary Bypass via Input Misclassification in ip-address Library
A trust-boundary bypass and Server-Side Request Forgery (SSRF) vulnerability exists in the ip-address library versions 10.1.1 through 10.2.0 due to structural input misclassification. The library fails to resolve and normalize transition IP notations, such as IPv4-mapped IPv6 (::ffff:0:0/96) and NAT64 (64:ff9b::/96) addresses, to their embedded IPv4 representations prior to evaluation. Consequently, standard security validation checks (e.g., isLoopback, isLinkLocal, isULA) return false for these addresses. This allows remote attackers to bypass application-level IP address filters, gaining unauthorized access to internal resources, cloud metadata interfaces, and local services on dual-stack hosts or environments utilizing NAT64 gateways.
