Prior to 0.4.0, the DELETE /studiocms_api/dashboard/api-tokens endpoint allows any authenticated user with editor privileges or above to revoke API tokens belonging to any other user, including admin and owner accounts. The handler accepts tokenID and userID directly from the request payload without verifying token ownership, caller identity, or role hierarchy. This enables targeted denial of service against critical integrations and automations. This vulnerability is fixed in 0.4.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H","score":7.1},"cwes":["CWE-639","CWE-863"],"references":["https://github.com/withstudiocms/studiocms/commit/9eec9c3b45523b635cfe16d55aa55afabacbebe3","https://github.com/withstudiocms/studiocms/releases/tag/studiocms@0.4.0","https://github.com/withstudiocms/studiocms/security/advisories/GHSA-8rgj-vrfr-6hqr"],"products":["studiocms:studiocms"],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-30945","score":0.0048,"percentile":0.4145,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-8rgj-vrfr-6hqr","url":"https://osv.dev/vulnerability/GHSA-8rgj-vrfr-6hqr","summary":"StudioCMS: IDOR — Arbitrary API Token Revocation Leading to Denial of Service","modified":"2026-03-13T04:42:12.560444Z","packages":[{"ecosystem":"npm","name":"studiocms","purl":"pkg:npm/studiocms","ranges":["<0.4.0"],"fixed":["0.4.0"]}]}],"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).
