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'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's storage credential can reach, including other tenants' 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.","state":0,"publishedAt":"2026-08-19T22:16:40.6+00:00","modifiedAt":"2026-10-26T10:10:00.14+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","score":5.4,"severity":"MEDIUM"}],"references":["https://github.com/tinacms/tinacms/commit/d44558e9b4502d4f4fc2c970d22985339fe2b6ce","https://github.com/tinacms/tinacms/pull/7088","https://github.com/tinacms/tinacms/releases/tag/next-tinacms-s3@23.0.4","https://github.com/tinacms/tinacms/security/advisories/GHSA-8mq9-5fw2-5rm4"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-59992","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-639","CWE-862"],"productCriteria":[],"sourceDates":{"published":"2026-08-19T22:16:40.600","lastModified":"2026-10-26T10:10:00.140"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
