{"id":"GHSA-vj8j-973f-r65j","summary":"Duplicate Advisory: Grav: Incomplete callable validation in blueprint dynamic fields allows arbitrary static method invocation and file disclosure","details":"### Duplicate Advisory\nThis advisory has been withdrawn because it is a duplicate of GHSA-7pgq-cr25-xvc8. This link is maintained to preserve external references.\n\n### Original Description\nGrav CMS versions 2.0.7 through 2.0.10 fail to validate fully-qualified static method calls (Class::method) in blueprint dynamic-field directives because Blueprint::isSafeDynamicCall() only applies its dangerous-callable denylist to strings that do not contain '::'. An account with only page-editing rights (admin.pages, not super-admin or admin.pages_twig) can plant a directive in a page's form-field frontmatter that invokes an arbitrary public static PHP method with attacker-controlled arguments. Using built-in gadget methods this allows reading of any server-readable file (disclosed to anonymous visitors of the crafted page) and arbitrary creation/copying of files and directories under the web-server account. Fixed in 2.0.11.","modified":"2026-09-17T17:30:05.677749352Z","published":"2026-08-03T15:32:48Z","withdrawn":"2026-09-17T17:16:30Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-09-17T17:16:30Z","nvd_published_at":"2026-08-03T14:16:29Z","cwe_ids":["CWE-94"],"severity":"HIGH"},"references":[{"type":"WEB","url":"https://github.com/getgrav/grav/security/advisories/GHSA-7pgq-cr25-xvc8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-69088"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/grav-cms-through-arbitrary-method-invocation-via-blueprint"}],"affected":[{"package":{"name":"getgrav/grav","ecosystem":"Packagist","purl":"pkg:composer/getgrav/grav"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.0.7"},{"last_affected":"2.0.10"}]}],"versions":["2.0.10","2.0.7","2.0.8","2.0.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/08/GHSA-vj8j-973f-r65j/GHSA-vj8j-973f-r65j.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},{"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
