      <title>CVE-2026-69263 — Flowise: CVE-2025-8943 Patch Bypass: npm_config_yes bypasses MCP environment variable blocklist (Unauthenticated RCE)</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-69263</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; FlowiseAI Flowise&lt;/p&gt;
&lt;p&gt;Flowise is a drag &amp;amp; drop user interface to build a customized large language model flow. Prior to 3.1.3, the mitigation for CVE-2025-8943 blocked -y and --yes flags on npx, but packages/components/nodes/tools/MCP/core.ts denied only PATH, LD_LIBRARY_PATH, DYLD_LIBRARY_PATH, and NODE_OPTIONS by exact environment-variable name. Because npm reads configuration from npm_config_* variables, setting npm_config_yes=true reproduced --yes behavior without using a blocked flag, causing npx to auto-install and execute the named package when a Custom MCP server launched. This issue is fixed in version 3.1.3.&lt;/p&gt;</description>
