Prior to 2.1.8 , the TinaCMS CLI dev server combines a permissive CORS configuration (Access-Control-Allow-Origin: *) with the path traversal vulnerability (previously reported) to enable a browser-based drive-by attack. A remote attacker can enumerate the filesystem, write arbitrary files, and delete arbitrary files on developer's machines by simply tricking them into visiting a malicious website while tinacms dev is running. This vulnerability is fixed in 2.1.8.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","score":9.6},"cwes":["CWE-22","CWE-942"],"references":["https://github.com/tinacms/tinacms/security/advisories/GHSA-8pw3-9m7f-q734","https://github.com/tinacms/tinacms/security/advisories/GHSA-8pw3-9m7f-q734"],"products":["ssw:tinacms\\/cli"],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-28792","score":0.00568,"percentile":0.4709,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-8pw3-9m7f-q734","url":"https://osv.dev/vulnerability/GHSA-8pw3-9m7f-q734","summary":"TinaCMS CLI Dev Server Vulnerable to Cross-Origin File Exfiltration via CORS Misconfiguration + Path Traversal in TinaCMS","modified":"2026-03-14T07:11:21.300936Z","packages":[{"ecosystem":"npm","name":"@tinacms/cli","purl":"pkg:npm/%40tinacms/cli","ranges":["<2.1.8"],"fixed":["2.1.8"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
