      <title>CVE-2026-59992 — Tina: Broken Access Control: arbitrary bucket-key write/delete in `next-tinacms-s3` (and sibling production media adapt…</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-59992</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; tinacms, tinacms next-tinacms-s3, tinacms next-tinacms-dos, tinacms next-tinacms-azure, tinacms next-tinacms-cloudinary&lt;/p&gt;
&lt;p&gt;Tina is a headless content management system. Prior to next-tinacms-s3 23.0.4, next-tinacms-dos 23.0.4, next-tinacms-azure 14.0.4, and next-tinacms-cloudinary 26.0.4, the first-party production media adapters pass attacker-controlled object keys to storage SDK upload and delete operations without enforcing the operator&amp;#39;s configured mediaRoot. In packages/next-tinacms-s3/src/handlers.ts, createMediaHandler accepts req.query.key for a signed PutObject URL and the DELETE path uses req.query.media as the DeleteObjectCommand key. The same missing key-boundary check exists in packages/next-tinacms-dos/src/handlers.ts, packages/next-tinacms-azure/src/handlers.ts, and packages/next-tinacms-cloudinary/src/handlers.ts. An authenticated CMS editor can therefore create or delete objects anywhere the deployment&amp;#39;s storage credential can reach, including other tenants&amp;#39; or non-media objects. These issues are fixed in next-tinacms-s3 23.0.4, next-tinacms-dos 23.0.4, next-tinacms-azure 14.0.4, and next-tinacms-cloudinary 26.0.4.&lt;/p&gt;</description>
