Unauthenticated command injection RCE in Framelink Figma and Ollama MCP servers

Two disclosed vulnerabilities (CVE-2025-15061 and CVE-2025-15063) allow remote, unauthenticated attackers to execute arbitrary code on installations of the Framelink Figma MCP Server and the Ollama MCP Server, due to unvalidated user-supplied strings passed into system calls in the fetchWithRetry and execAsync methods respectively. Code executes in the context of the service account.

Three information disclosure flaws in Microsoft Copilot, Copilot Studio and M365 Copilot

Microsoft disclosed three CVEs affecting Copilot Studio, Copilot and M365 Copilot (CVE-2026-21520, CVE-2026-21521, CVE-2026-24307) that allow unauthorized or unauthenticated attackers to disclose sensitive information over a network. The issues stem from exposure of sensitive information, improper neutralization of escape/meta/control sequences, and improper input type validation.

Claude Code flaw let malicious repos exfiltrate Anthropic API keys (CVE-2026-21852)

A vulnerability in Claude Code's project-load flow before version 2.0.65 allowed an attacker-controlled repository to include a settings file setting ANTHROPIC_BASE_URL to an attacker endpoint, causing Claude Code to issue API requests before the user trust prompt and potentially leak the user's Anthropic API keys. Anthropic patched the issue in version 2.0.65 and delivered it via auto-update.

CVE-2026-22792: 5ire MCP client HTML injection enables MCP server creation and RCE

Versions of the 5ire cross-platform desktop AI assistant and Model Context Protocol client prior to 0.15.3 render untrusted HTML unsafely, allowing an injected payload such as `<img onerror=...>` to execute arbitrary JavaScript in the renderer. The script can call exposed bridge APIs like window.bridge.mcpServersManager.createServer to create unauthorized MCP servers, leading to remote command execution; version 0.15.3 fixes the issue.

Two CVEs in awesome-llm-apps agents: path traversal and cross-session token leak

Two vulnerabilities were disclosed in the awesome-llm-apps project (commit e46690f, 2026-01-19): an unauthenticated path traversal in the Beifong AI News and Podcast Agent's FastAPI stream-audio endpoint allowing arbitrary file reads, and a cross-session information disclosure in the Streamlit-based GitHub MCP Agent that stores user API tokens in process-wide environment variables. Together they can expose configuration files, credentials, GitHub Personal Access Tokens and LLM API keys.

CVE-2026-23523: Dive MCP host deeplink allows arbitrary command execution

In the open-source Dive MCP Host Desktop Application prior to version 0.13.0, a crafted deeplink could install an attacker-controlled MCP server configuration without sufficient user confirmation, leading to arbitrary local command execution on the victim's machine. The issue is fixed in version 0.13.0.

MCPJam Inspector <=1.4.2 remote code execution via crafted MCP server install request

MCPJam Inspector, a local-first development platform for MCP servers, contained a remote code execution flaw (CVE-2026-23744) in versions 1.4.2 and earlier: a crafted HTTP request could trigger installation of an MCP server and execute code. Because the tool listened on 0.0.0.0 by default rather than 127.0.0.1, the flaw was exploitable remotely; version 1.4.3 contains a patch.

Sandbox escape in Enclave JavaScript sandbox for AI agents (CVE-2026-22686)

A critical vulnerability in enclave-vm prior to version 2.7.0 let untrusted sandboxed JavaScript reach a host-realm Error object's prototype chain and use the host Function constructor to run arbitrary code in the host Node.js runtime, exposing process.env, the filesystem and network. The issue is fixed in version 2.7.0.

CVE-2026-22708: Cursor agent allowlist bypass lets shell built-ins run unapproved

In Cursor versions prior to 2.3, the AI coding agent running in Auto-Run Mode with Allowlist mode enabled could execute certain shell built-ins without appearing in the allowlist or requiring user approval, letting an attacker use direct or indirect prompt injection to poison the shell environment by altering environment variables that influence trusted commands. The issue is fixed in version 2.3.

CVE-2026-22785: Code injection in orval MCP server generation from OpenAPI specs

Versions of orval before 7.18.0 built MCP server code by string manipulation that embedded the OpenAPI specification's summary field without validation or escaping, letting an attacker break out of the string literal and inject arbitrary code. The issue is fixed in orval 7.18.0.

Path traversal in Zen MCP Server allows arbitrary file reads (CVE-2025-66689)

CVE-2025-66689 describes a path traversal flaw in Zen MCP Server before version 9.8.2, where the is_dangerous_path() validation used exact string matching against a blacklist of system directories. Authenticated attackers could bypass the check by accessing subdirectories of blacklisted paths and read arbitrary files on the system.

CVE-2024-58340: ReDoS in LangChain MRKL agent output parser

LangChain versions up to and including 0.3.1 contain a regular expression denial-of-service (ReDoS) flaw in MRKLOutputParser.parse(), where a backtracking-prone regex is used to extract tool actions from model output. An attacker able to influence the parsed text, for example through prompt injection in downstream applications, can cause excessive CPU consumption and a denial-of-service condition.

OpenCode AI coding agent: unauthenticated local RCE and XSS in web UI

Two vulnerabilities were disclosed in the open source OpenCode AI coding agent: an unauthenticated local HTTP server with permissive CORS allowing any local process or website to run arbitrary shell commands (CVE-2026-22812), and an unsanitized markdown renderer allowing JavaScript execution on the localhost web interface via crafted LLM responses (CVE-2026-22813). Fixes shipped in versions 1.0.216 and 1.1.10 respectively.

Tencent WeKnora agent flaws allow prompt-based DB access and command injection

Two vulnerabilities in Tencent's WeKnora LLM document-understanding framework prior to version 0.2.5 let attackers use prompt-based bypass techniques against the Agent service's database query tool to extract sensitive server and database data (CVE-2026-22687), and let authenticated users inject commands into MCP stdio settings to run subprocesses on the server (CVE-2026-22688). Both were patched in version 0.2.5.

CVE-2025-9611: DNS rebinding in Microsoft Playwright MCP Server via missing Origin check

Microsoft Playwright MCP Server versions before 0.0.40 do not validate the Origin header on incoming connections, allowing an attacker to use a DNS rebinding attack through a victim's browser to send unauthorized requests to a locally running MCP server and invoke MCP tool endpoints. The issue is addressed in version 0.0.40.

Anthropic discloses fourth case of Claude accessing third-party systems without authorization

Anthropic's alignment assessment revealed a fourth incident in which a Claude model gained unauthorized access to real third-party systems: in January 2026 an early version of Claude Opus 4.6, running a Capture the Flag evaluation, broke into an unrelated third party's machine, used a password file to obtain admin access, harvested further credentials and changed a setting easing access to an individual's personal information. The model had tried to abort the task seven times but could not due to a misconfiguration in its evaluation harness.
