{"id":"CVE-2025-27407","summary":"Remote code execution when loading a crafted GraphQL schema","details":"graphql-ruby is a Ruby implementation of GraphQL. Starting in version 1.11.5 and prior to versions 1.11.8, 1.12.25, 1.13.24, 2.0.32, 2.1.14, 2.2.17, and 2.3.21, loading a malicious schema definition in `GraphQL::Schema.from_introspection` (or `GraphQL::Schema::Loader.load`) can result in remote code execution. Any system which loads a schema by JSON from an untrusted source is vulnerable, including those that use GraphQL::Client to load external schemas via GraphQL introspection. Versions 1.11.8, 1.12.25, 1.13.24, 2.0.32, 2.1.14, 2.2.17, and 2.3.21 contain a patch for the issue.","aliases":["GHSA-q92j-grw3-h492"],"modified":"2026-05-15T04:13:19.302992244Z","published":"2025-03-12T18:15:57.957Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/27xxx/CVE-2025-27407.json","cwe_ids":["CWE-94"],"cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://about.gitlab.com/releases/2025/03/12/patch-release-gitlab-17-9-2-released"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/08/msg00002.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/27xxx/CVE-2025-27407.json"},{"type":"ADVISORY","url":"https://github.com/rmosolgo/graphql-ruby/security/advisories/GHSA-q92j-grw3-h492"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-27407"},{"type":"FIX","url":"https://github.com/rmosolgo/graphql-ruby/commit/28233b16c0eb9d0fb7808f4980e061dc7507c4cd"},{"type":"FIX","url":"https://github.com/rmosolgo/graphql-ruby/commit/2d2f4ed1f79472f8eed29c864b039649e1de238f"},{"type":"FIX","url":"https://github.com/rmosolgo/graphql-ruby/commit/5c5a7b9a9bdce143be048074aea50edb7bb747be"},{"type":"FIX","url":"https://github.com/rmosolgo/graphql-ruby/commit/6eca16b9fa553aa957099a30dbde64ddcdac52ca"},{"type":"FIX","url":"https://github.com/rmosolgo/graphql-ruby/commit/d0963289e0dab4ea893bbecf12bb7d89294957bb"},{"type":"FIX","url":"https://github.com/rmosolgo/graphql-ruby/commit/d1117ae0361d9ed67e0795b07f5c3e98e62f3c7c"},{"type":"FIX","url":"https://github.com/rmosolgo/graphql-ruby/commit/e3b33ace05391da2871c75ab4d3b66e29133b367"},{"type":"PACKAGE","url":"https://github.com/github-community-projects/graphql-client"}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H"}]}
