{"id":"CVE-2026-25492","aliases":["GHSA-96pq-hxpw-rgh8"],"url":"https://o3.security/vulnerability/CVE-2026-25492","summary":"Craft has a save_images_Asset graphql mutation can be abused to exfiltrate AWS credentials of underlying host","details":"Craft CMS is a content management system. In Craft versions 3.5.0 through 4.16.17 and 5.0.0-RC1 through 5.8.21, the save_images_Asset GraphQL mutation can be abused to fetch internal URLs by providing a domain name that resolves to an internal IP address, bypassing hostname validation. When a non-image file extension such as .txt is allowed, downstream image validation is bypassed, which can allow an authenticated attacker with permission to use save_images_Asset to retrieve sensitive data such as AWS instance metadata credentials from the underlying host. This issue is patched in versions 4.16.18 and 5.8.22.","published":"2026-02-09T19:33:24.366Z","modified":"2026-08-07T11:50:42.087973449Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"craftcms/craft","fixedVersion":"5.8.22"},{"ecosystem":"Packagist","name":"craftcms/craft","fixedVersion":"4.16.18"}],"fix":{"url":"https://github.com/craftcms/cms/commit/e838a221df2ab15cd54248f22fc8355d47df29ff","label":"craftcms/cms@e838a22"},"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-2026-25492.json"},{"type":"ADVISORY","url":"https://github.com/craftcms/cms/security/advisories/GHSA-96pq-hxpw-rgh8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25492"},{"type":"FIX","url":"https://github.com/craftcms/cms/commit/e838a221df2ab15cd54248f22fc8355d47df29ff"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:42.087973449Z"}}
