      <title>CVE-2026-56277 — Flowise - Hardcoded CORS Wildcard in TTS Endpoint</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-56277</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Flowise&lt;/p&gt;
&lt;p&gt;Flowise before 3.1.2 sets Access-Control-Allow-Origin to a hardcoded wildcard (*) on its text-to-speech (TTS) generation endpoint (packages/server/src/controllers/text-to-speech/index.ts), independent of the server&amp;#39;s configured CORS policy. This bypasses the server&amp;#39;s otherwise restrictive default CORS configuration (getCorsOptions()) and allows any webpage to make cross-origin requests that trigger TTS generation using stored credentials, enabling drive-by cross-origin credential abuse.&lt;/p&gt;</description>
