{"id":"CVE-2026-25497","summary":"Craft has a GraphQL Asset Mutation Privilege Escalation","details":"Craft is a platform for creating digital experiences. In Craft versions from 4.0.0-RC1 to before 4.17.0-beta.1 and 5.9.0-beta.1, there is a Privilege Escalation vulnerability in Craft CMS’s GraphQL API that allows an authenticated user with write access to one asset volume to escalate their privileges and modify/transfer assets belonging to any other volume, including restricted or private volumes to which they should not have access. The saveAsset GraphQL mutation validates authorization against the schema-resolved volume but fetches the target asset by ID without verifying that the asset belongs to the authorized volume. This allows unauthorized cross-volume asset modification and transfer. This vulnerability is fixed in 4.17.0-beta.1 and 5.9.0-beta.1.","aliases":["GHSA-fxp3-g6gw-4r4v"],"modified":"2026-08-12T03:51:21.338665335Z","published":"2026-02-09T19:50:08.543Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25497.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-639"]},"references":[{"type":"WEB","url":"https://github.com/craftcms/cms/releases/tag/5.8.22"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25497.json"},{"type":"ADVISORY","url":"https://github.com/craftcms/cms/security/advisories/GHSA-fxp3-g6gw-4r4v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25497"},{"type":"FIX","url":"https://github.com/craftcms/cms/commit/ac7edf868c1a81fd9c4dc49d3b3edf1cce113409"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/craftcms/cms","events":[{"introduced":"04755d93f86d07cc183db47db8a0eee106892e30"},{"fixed":"8e23a7a14d50f169c10a487348c993384d479e06"},{"introduced":"daac7c1da2f701f2e9ddee1da1457ce61660b581"},{"fixed":"42cef196d68dd8d48ceaab89b2c9e2edd2cecbe8"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"5.0.0-RC1"},{"fixed":"5.8.22"},{"introduced":"4.0.0-RC1"},{"fixed":"4.17.0-beta.1"}]}},{"type":"GIT","repo":"https://github.com/nystudio107/craft-seomatic","events":[{"introduced":"a31f7d211b52d55d274c66a291310ceec64c733f"},{"last_affected":"a31f7d211b52d55d274c66a291310ceec64c733f"}],"database_specific":{"cpe":"cpe:2.3:a:craftcms:craft_cms:4.0.0:-:*:*:*:*:*:*","extracted_events":[{"introduced":"4.0.0-NA"},{"last_affected":"4.0.0-NA"}],"source":"CPE_STRING"}}],"versions":["4.0.0-NA","4.0.0-rc1","4.0.0-rc2","4.0.0-rc3","5.0.0-NA","5.0.0-rc1","4.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-25497.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
