{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/77221?format=json","vulnerability_id":"VCID-3d69-y1fs-h3e4","summary":"StudioCMS is a server-side-rendered, Astro native, headless content management system. Prior to 0.3.1, the S3 storage manager's isAuthorized() function is declared async (returns Promise<boolean>) but is called without await in both the POST and PUT handlers. Since a Promise object is always truthy in JavaScript, !isAuthorized(type) always evaluates to false, completely bypassing the authorization check. Any authenticated user with the lowest visitor role can upload, delete, rename, and list all files in the S3 bucket. This vulnerability is fixed in 0.3.1.","aliases":[{"alias":"CVE-2026-32101"},{"alias":"GHSA-mm78-fgq8-6pgr"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/374648?format=json","purl":"pkg:npm/%40studiocms/s3-storage@0.3.1","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540studiocms/s3-storage@0.3.1"}],"affected_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/965428?format=json","purl":"pkg:npm/%40studiocms/s3-storage@0.0.0-beta.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-3d69-y1fs-h3e4"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540studiocms/s3-storage@0.0.0-beta.0"},{"url":"http://public2.vulnerablecode.io/api/packages/965429?format=json","purl":"pkg:npm/%40studiocms/s3-storage@0.1.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-3d69-y1fs-h3e4"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540studiocms/s3-storage@0.1.0"},{"url":"http://public2.vulnerablecode.io/api/packages/965430?format=json","purl":"pkg:npm/%40studiocms/s3-storage@0.1.1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-3d69-y1fs-h3e4"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540studiocms/s3-storage@0.1.1"},{"url":"http://public2.vulnerablecode.io/api/packages/965431?format=json","purl":"pkg:npm/%40studiocms/s3-storage@0.2.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-3d69-y1fs-h3e4"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540studiocms/s3-storage@0.2.0"},{"url":"http://public2.vulnerablecode.io/api/packages/965432?format=json","purl":"pkg:npm/%40studiocms/s3-storage@0.2.1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-3d69-y1fs-h3e4"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540studiocms/s3-storage@0.2.1"},{"url":"http://public2.vulnerablecode.io/api/packages/965433?format=json","purl":"pkg:npm/%40studiocms/s3-storage@0.3.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-3d69-y1fs-h3e4"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540studiocms/s3-storage@0.3.0"}],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-32101","reference_id":"","reference_type":"","scores":[{"value":"0.00053","scoring_system":"epss","scoring_elements":"0.17227","published_at":"2026-06-14T12:55:00Z"},{"value":"0.00053","scoring_system":"epss","scoring_elements":"0.17078","published_at":"2026-06-11T12:55:00Z"},{"value":"0.00053","scoring_system":"epss","scoring_elements":"0.17253","published_at":"2026-06-13T12:55:00Z"},{"value":"0.00053","scoring_system":"epss","scoring_elements":"0.17239","published_at":"2026-06-12T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-32101"},{"reference_url":"https://github.com/withstudiocms/studiocms","reference_id":"","reference_type":"","scores":[{"value":"7.6","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:L"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/withstudiocms/studiocms"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32101","reference_id":"","reference_type":"","scores":[{"value":"7.6","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:L"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32101"},{"reference_url":"https://github.com/advisories/GHSA-mm78-fgq8-6pgr","reference_id":"GHSA-mm78-fgq8-6pgr","reference_type":"","scores":[{"value":"HIGH","scoring_system":"cvssv3.1_qr","scoring_elements":""}],"url":"https://github.com/advisories/GHSA-mm78-fgq8-6pgr"},{"reference_url":"https://github.com/withstudiocms/studiocms/security/advisories/GHSA-mm78-fgq8-6pgr","reference_id":"GHSA-mm78-fgq8-6pgr","reference_type":"","scores":[{"value":"7.6","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:L"},{"value":"HIGH","scoring_system":"cvssv3.1_qr","scoring_elements":""},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:P/P:M/B:A/M:M/D:T/2026-03-12T19:51:12Z/"}],"url":"https://github.com/withstudiocms/studiocms/security/advisories/GHSA-mm78-fgq8-6pgr"}],"weaknesses":[{"cwe_id":863,"name":"Incorrect Authorization","description":"The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
