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":"2026-08-19T21:30:51.975+00:00","modifiedAt":"2026-08-21T16:48:12.641+00:00","affected":[{"ecosystem":"Vendor product","name":"tinacms","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"tinacms\",\n                    \"product\": \"tinacms\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 23.0.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"next-tinacms-s3","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"tinacms\",\n                    \"product\": \"next-tinacms-s3\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 23.0.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"next-tinacms-dos","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"tinacms\",\n                    \"product\": \"next-tinacms-dos\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 23.0.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"next-tinacms-azure","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"tinacms\",\n                    \"product\": \"next-tinacms-azure\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 14.0.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"next-tinacms-cloudinary","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"tinacms\",\n                    \"product\": \"next-tinacms-cloudinary\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 26.0.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","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/security/advisories/GHSA-8mq9-5fw2-5rm4","https://github.com/tinacms/tinacms/pull/7088","https://github.com/tinacms/tinacms/commit/d44558e9b4502d4f4fc2c970d22985339fe2b6ce","https://github.com/tinacms/tinacms/releases/tag/next-tinacms-s3@23.0.4"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-59992","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-59992","identifiers":["CVE-2026-59992"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
