A publicly disclosed server-side request forgery vulnerability in the axios-based HTTP request handler of the web-scraper server in the open-source mcp-data-vis MCP project allows remote attackers to make the server issue arbitrary requests. The maintainer was notified via a GitHub issue but has not responded, and the rolling-release project has no fixed version.

AnythingLLM versions prior to 1.12.1 rendered chart captions from LLM output through a markdown renderer without DOMPurify sanitisation, allowing stored DOM-level XSS. An attacker who could influence the model's output, typically via indirect prompt injection in a shared workspace document, could execute script in other users' browsers when they opened the conversation.

24 Apr 2026 · LangChain
Two vulnerabilities in LangChain packages allowed SSRF protections to be bypassed: HTMLHeaderTextSplitter.split_text_from_url() followed unvalidated redirects (CVE-2026-41481), and langchain-openai's _url_to_size() helper was subject to a TOCTOU/DNS rebinding window (CVE-2026-41488), potentially allowing requests to internal, localhost or cloud metadata endpoints and leaking internal data to callers.

23 Apr 2026 · Paperclip
Two vulnerabilities in @paperclipai/server, a Node.js/React platform that orchestrates a team of AI agents to run a business, allow remote code execution on the server host: one lets an attacker with an Agent API key inject shell commands via a self-updatable adapterConfig provisionCommand field, and another lets an unauthenticated attacker chain six API calls for full RCE on default 'authenticated' mode deployments. Both are fixed in version 2026.416.0.

23 Apr 2026 · OpenClaw
OpenClaw versions before 2026.3.28 contain a vulnerability that lets LLM agents silently disable execution approval through the config.patch parameter. Remote attackers can abuse this to bypass security controls and run unauthorized operations without user consent.

CVE-2026-40576: excel-mcp-server versions up to and including 0.1.7 fail to confine file operations to the EXCEL_FILES_PATH directory, letting an unauthenticated network attacker read, write and overwrite arbitrary files via crafted filepath arguments to any of its 25 MCP tool handlers when run in SSE or Streamable-HTTP mode.

Next AI Draw.io versions prior to 0.4.15 accumulated entire HTTP request bodies into memory in three POST handlers (/api/state, /api/restore, /api/history-svg) of its embedded sidecar, so a large payload (e.g. 500 MiB) could exhaust the Node.js heap and crash the MCP server. The issue is fixed in version 0.4.15.

21 Apr 2026 · FlowiseAI
Three vulnerabilities in FlowiseAI's Flowise LLM flow builder prior to version 3.1.0 allow remote code execution on the server: unauthenticated attackers can use prompt injection against chatflows using the CSV Agent or Airtable Agent nodes to have the LLM emit unsandboxed Python that runs attacker commands, while an authenticated user can abuse unsafe serialization of stdio commands in the MCP adapter to execute arbitrary commands. All three are fixed in Flowise 3.1.0.

Public disclosures describe two vulnerabilities in the open-source copilot-api project (versions up to 0.7.0): a permissive cross-domain policy in the cors function of src/server.ts at the token endpoint, and reliance on reverse DNS resolution via a manipulated Host header on the /token endpoint. Both are remotely exploitable and exploit details have been made public.

A log injection flaw in the AAP MCP server lets an unauthenticated remote attacker send crafted input to the `toolsetroute` parameter, which is written to logs unsanitised. Injected newlines and ANSI escape sequences can hide real log entries and forge new ones, enabling social engineering of operators into running dangerous commands or visiting malicious URLs.

Two vulnerabilities were disclosed in Anthropic's agentic coding tool Claude Code: CVE-2026-35603, where Windows versions before 2.1.75 loaded a system-wide settings file from a world-writable ProgramData path letting a low-privileged local user plant malicious configuration, and CVE-2026-39861, where versions before 2.1.64 allowed a sandbox escape via symlinks that the unsandboxed process followed to write outside the workspace, triggerable through prompt injection. Both issues were fixed in the noted releases.

FastGPT, an AI agent building platform, contained two NoSQL injection vulnerabilities (CVE-2026-40351 and CVE-2026-40352) in versions before 4.14.9.5. The login endpoint accepted MongoDB query operators as a password, letting unauthenticated attackers log in as any user including the root administrator, while the password change endpoint allowed bypassing old-password verification for full account takeover and persistence. Both were fixed in version 4.14.9.5.

In mcp-framework 0.2.21 and below, the HTTP transport's readRequestBody() concatenates request body chunks without enforcing the maxMessageSize setting, letting a remote unauthenticated attacker crash any mcp-framework HTTP server with a single large POST to /mcp via memory exhaustion.

15 Apr 2026 · Flux159
Versions 3.4.0 and earlier of mcp-server-kubernetes, a Model Context Protocol server for Kubernetes cluster management, built a kubectl command by string concatenation and naive space-splitting in the port_forward tool, allowing attackers to inject arbitrary kubectl flags. This could expose internal Kubernetes services to the network (via --address=0.0.0.0) or target other namespaces, and could be triggered indirectly through prompt injection against connected AI agents; fixed in version 3.5.0.

In Splunk MCP Server app versions below 1.0.3, session and authorization tokens were recorded in clear text where a user with access to the Splunk `_internal` index or the `mcp_tool_admin` capability could view them. Exploitation requires local access to log files or administrative access to internal indexes, and the issue is addressed in version 1.0.3.

15 Apr 2026 · Windsurf
A prompt injection vulnerability in Windsurf 1.9544.26 lets remote attackers embed malicious instructions in HTML content that the AI coding tool processes, causing it to modify the local MCP configuration and register a malicious MCP STDIO server. This results in arbitrary command execution on the victim system without further user interaction.

Jaaz version 1.0.30 contains a remote code execution flaw in its MCP STDIO command execution handling, allowing a remote attacker to send crafted network requests to the network-accessible application and run arbitrary commands in the context of the Jaaz service. Successful exploitation could lead to full compromise of the affected system.

Two vulnerabilities were disclosed in the FastGPT AI agent building platform: an unauthenticated SSRF via the /api/core/app/mcpTools/runTool endpoint (CVE-2026-40100, fixed in 4.14.10.3) and a broken access control (IDOR/BOLA) issue allowing any authenticated team to access and execute other teams' applications (CVE-2026-40252, fixed in 4.14.10.4). Both enable access to resources beyond the attacker's authorisation, including cross-tenant data exposure and execution of private AI workflows.
