CVE-2026-40933

Flowise: Authenticated RCE via MCP adapters. Prior to 3.1.0, unsafe serialization of stdio commands in the MCP adapter allows an authenticated attacker to add an MCP stdio server and run arbitrary OS commands, due to a bug in input sanitization in the Custom MCP configuration (http://localhost:30...

Anthropic MCP Design Vulnerability Enables RCE, Threatening AI Supply Chain

Cybersecurity researchers have discovered a critical "by design" weakness in the Model Context Protocol's MCP architecture that could pave the way for remote code execution and have a cascading effect on the artificial intelligence AI supply chain. "This flaw enables Arbitrary Command Execution R...

CVE-2026-30625

Upsonic 0.71.6 contains a remote code execution vulnerability in its MCP server/task creation functionality. The application allows users to define MCP tasks with arbitrary command and args values. Although an allowlist exists, certain allowed commands npm, npx accept argument flags that enable...

CVE-2026-30617

LangChain-ChatChat 0.3.1 contains a remote code execution vulnerability in its MCP STDIO server configuration and execution handling. A remote attacker can access the publicly exposed MCP management interface and configure an MCP STDIO server with attacker-controlled commands and arguments. When...

Jaaz 安全漏洞

Jaaz is an AI-driven multi-modal creative design platform developed by 11cafe. Version 1.0.30 of Jaaz contains a security vulnerability, which stems from improper handling of MCP STDIO command execution. This vulnerability could allow remote attackers to execute arbitrary commands...

CVE-2026-30615

A prompt injection vulnerability in Windsurf 1.9544.26 allows remote attackers to execute arbitrary commands on a victim system. When Windsurf processes attacker-controlled HTML content, malicious instructions can cause unauthorized modification of the local MCP configuration and automatic...

CVE-2026-39417

Affected software : MaxKB, specifically versions 2.7.1 and earlier. Vulnerability details : An incomplete fix for CVE-2025-53928 leaves a Remote Code Execution in the MCP node of the workflow engine. The fix only patched the path loading MCP config from the database; the else branch that loads mc...

CVE-2026-33948 jq: Embedded-NUL Truncation in CLI JSON Input Path Causes Prefix-Only Validation of Malformed Input

jq is a command-line JSON processor. Commits before 6374ae0bcdfe33a18eb0ae6db28493b1f34a0a5b contain a vulnerability where CLI input parsing allows validation bypass via embedded NUL bytes. When reading JSON from files or stdin, jq uses strlen to determine buffer length instead of the actual byte...

Medium: polkit

Issue Overview: A flaw was found in polkit. A local user can exploit this by providing a specially crafted, excessively long input to the polkit-agent-helper-1 setuid binary via standard input stdin. This unbounded input can lead to an out-of-memory OOM condition, resulting in a Denial of Service...

CVE-2026-4897

CVE-2026-4897 describes a vulnerability in polkit where a local user can feed an excessively long input to the setuid binary polkit-agent-helper-1 via stdin. The unbounded input can trigger an out-of-memory condition, leading to a Denial of Service on the system. Affected component: polkit’s help...

EUVD-2026-14591

OpenClaw before 2026.2.19 contains a command injection vulnerability in tools.exec.safeBins that allows attackers to bypass stdin-only restrictions using sort output flags or recursive grep flags. Attackers can exploit this to perform arbitrary file writes via sort -o or recursive file reads via...

CVE-2026-32909

OpenClaw before 2026.2.19 contains a command-injection vulnerability in tools.exec.safeBins that lets an attacker bypass stdin-only restrictions by using sort output flags or recursive grep flags. This can enable arbitrary file writes via sort -o and recursive file reads via grep -R, bypassing th...

CVE-2026-31996

OpenClaw versions prior to 2026.2.19 tools.exec.safeBins contains an input validation bypass vulnerability that allows attackers to execute unintended filesystem operations through sort output flags or recursive grep flags. Attackers with command execution access can leverage sort -o flag for...

CVE-2026-25966

A flaw was found in ImageMagick. The "secure" security policy, intended to prevent reading and writing from standard streams, can be bypassed. An attacker can exploit this by using fd: pseudo-filenames, which are not properly blocked by the policy. This allows the attacker to circumvent the...
