A flaw was found in the `cluster-proxy-addon` component of Multicluster Engine for Kubernetes. This vulnerability allows an unauthenticated attacker, who can access the user-facing route, to bypass authentication and authorization checks. By manipulating URL path segments, the attacker can proxy requests to arbitrary services across any managed cluster. This enables unauthorized access to internal services that would otherwise be protected, potentially leading to information disclosure or further compromise of the cluster environment.

CVE-2026-714289.3 CRI—
———The unstructured library provides open-source components for ingesting and pre-processing images and text documents, such as PDFs, HTML, Word docs, and many more. From 0.4.7 until 0.24.0, the url argument of partition, partition_html, and partition_md is fetched without host validation in unstructured/partition/auto.py, unstructured/partition/html/partition.py, and unstructured/partition/md.py. An attacker who controls that URL can make a server-side ingestion service request loopback addresses, internal HTTP services, or cloud metadata endpoints through direct targets, redirects, or DNS rebinding. The response body is returned as Element text, allowing internal response disclosure, and side-effecting GET endpoints may also be triggered. This issue is fixed in version 0.24.0.6hCVE-2026-658428.2 HIG—
———Plate is a rich-text editor with AI and shadcn/ui. Prior to 53.3.2, @platejs/docx-io fetches remote image URLs while converting attacker-controlled HTML through htmlToDocxBlob in a server-side or privileged environment. The converter can make requests to internal network resources and include the fetched image bytes in the generated DOCX, allowing server-side request forgery with response disclosure. Applications can also incur resource consumption from attacker-selected remote responses. This issue is fixed in version 53.3.2.6hCVE-2026-617047.5 HIG—
———Link Preview JS extracts web links information. Prior to 4.0.4, the resolveDNSHost mitigation in index.ts validates one resolved IP address but fetches the original hostname, allowing an attacker-controlled DNS server to return a public address during validation and a loopback or internal address during the final connection. This DNS rebinding condition bypasses the SSRF protection and can cause the server-side preview fetch to reach internal HTTP resources. Redirect handling is affected by the same validation-to-fetch mismatch. This issue is fixed in version 4.0.4.6hCVE-2026-63044——
———Server-Side Request Forgery (SSRF) vulnerability in Apache InLong. Any authenticated user (no admin role required) can cause the InLong Manager server to make outbound HTTP requests or TCP connections to
arbitrary internal hosts and ports.
This issue affects Apache InLong: from 2.0.0 before 2.4.0.
Users are advised to upgrade to Apache InLong's 2.4.0 or cherry-pick [1] to solve it.

———ATutor is vulnerable to Server-Side request forgery in import functionalities. An authenticated administrator can make the server request arbitrary internal HTTP endpoints, cloud metadata services, or local files via file:// if the PHP
environment permits URL wrappers.
Product is no longer actively supported and the vulnerabilities have not been fixed. Only version 2.2.4 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.7hCVE-2026-77085——
———n8n before 2.34.1 and 2.33.x before 2.33.4 contains an SSRF protection bypass in the SearXNG Agent tool. The tool sent requests to the user-supplied API URL using a raw HTTP client that did not route through n8n's centralized SSRF protection. On instances with N8N_SSRF_PROTECTION_ENABLED=true, an authenticated user with permission to create SearXNG credentials and configure a personal agent could set the API URL to an internal host, causing the n8n server to connect to that host and return the response content through the Agent chat output.11h
