      <title>CVE-2026-82291 — HeyForm Reflects Any Origin in CORS Responses While Allowing Credentials</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-82291</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; heyform&lt;/p&gt;
&lt;p&gt;HeyForm before 3.0.0-rc.8 reflects the request Origin header in CORS responses while allowing credentials, enabling cross-origin requests with authentication. Attackers can execute authenticated GraphQL queries from malicious pages visited by logged-in users to access workspaces, projects, forms, submissions, and respondent data, or modify account settings.&lt;/p&gt;</description>
