{"id":"CVE-2026-25497","aliases":["GHSA-fxp3-g6gw-4r4v"],"url":"https://o3.security/vulnerability/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.","published":"2026-02-09T19:50:08.543Z","modified":"2026-08-12T03:51:21.338665335Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"craftcms/cms","fixedVersion":"5.9.0-beta.1"},{"ecosystem":"Packagist","name":"craftcms/cms","fixedVersion":"4.17.0-beta.1"}],"fix":{"url":"https://github.com/craftcms/cms/commit/ac7edf868c1a81fd9c4dc49d3b3edf1cce113409","label":"craftcms/cms@ac7edf8"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:21.338665335Z"}}
