{"id":"CVE-2026-27938","summary":"WPGraphQL Repo Vulnerable to Command Injection via Unsanitized GitHub Actions Expression in Release Workflow","details":"WPGraphQL provides a GraphQL API for WordPress sites. Prior to version 2.9.1, the `wp-graphql/wp-graphql` repository contains a GitHub Actions workflow (`release.yml`) vulnerable to OS command injection through direct use of `${{ github.event.pull_request.body }}` inside a `run:` shell block. When a pull request from `develop` to `master` is merged, the PR body is injected verbatim into a shell command, allowing arbitrary command execution on the Actions runner. Version 2.9.1 contains a fix for the vulnerability.","aliases":["GHSA-4q9f-mjxf-rx7x"],"modified":"2026-08-12T03:51:21.768888495Z","published":"2026-02-26T01:10:26.985Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-78"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27938.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27938.json"},{"type":"ADVISORY","url":"https://github.com/wp-graphql/wp-graphql/security/advisories/GHSA-4q9f-mjxf-rx7x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27938"},{"type":"FIX","url":"https://github.com/wp-graphql/wp-graphql/commit/de0c2d590593f1099546ad517106e454a498bc58"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wp-graphql/wp-graphql","events":[{"introduced":"0"},{"fixed":"de0c2d590593f1099546ad517106e454a498bc58"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"2.9.1"}]}}],"versions":["wp-graphql/v2.9.0","wp-graphql-ide/v4.1.0","wp-graphql-smart-cache/v2.0.1","wp-graphql/v2.8.0","wp-graphql/v2.7.0","v1.0","v1.14.3","v1.13.7","v1.13.6","v1.13.5","v1.13.4","v1.13.3","v1.13.2","v1.13.1","v1.13.0","v1.12.3","v1.12.2","v1.12.1","v1.12.0","v1.11.3","v1.8.7","v1.11.2","v1.11.1","v1.11.0","v1.10.0","v1.9.1","v1.9.0","v1.8.6","v1.8.5","v1.8.4","v1.8.3","v1.8.2","v1.8.1","v1.8.0","v1.7.2","v1.7.1","v1.7.0","v1.6.12","v1.6.11","v1.6.10","v1.6.9","v1.6.8","v1.6.7","v1.6.6","v1.6.5","v1.6.4","v1.6.3","v1.6.2","v1.6.1","v1.6.0","v1.5.8","v1.5.7","v1.4.7","v1.5.6","v1.5.5","v1.5.4","v1.5.3","v1.5.2","v1.5.1","v1.5.0","v1.4.3","v1.4.0","v1.4.2","v1.4.1","v1.3.10","v1.3.9","v1.3.8","v1.3.7","v1.3.6","v1.3.5","v1.3.4","v1.3.3","v1.3.2","v1.3.1","v1.3.0","v1.2.6","v1.2.5","v1.2.4","1.2.2","v1.2.1","v1.1.8","v1.1.5","v1.1.4","v1.1.3","v1.1.2","v1.1.1","v1.1.0","v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v0.15.6","v0.15.4","v0.15.3","v0.15.2","v0.15.1","v0.15.0","v0.14.0","v0.13.3","v0.13.2","v0.13.1","v0.13.0","v0.12.3","v0.12.2","v0.12.1","v0.12.0","v0.11.0","v0.10.3","v0.10.2","v0.10.1","v0.10.0","v0.9.1","v0.9.0","v0.8.4","v0.8.3","v0.8.2","v0.8.1","v0.8.0","v0.7.1","v0.7.0","v0.6.3","v0.6.2","v0.6.1","v0.6.0","v0.5.1","v0.5.0","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.8","v0.3.7","v0.3.6","v0.3.5","v0.3.2","v0.3.01","v0.3.0","v0.2.3","v0.2.2","v0.2.1","v0.2.0","v0.1.4","v0.1.3","v0.1.2","v0.1.1","v0.1.0","v0.0.34","v0.0.33","v0.0.32","v0.0.31","v0.0.30","v0.0.29","v0.0.28","v0.0.27","v0.0.26","v0.0.25","v0.0.24","v0.0.23","v0.0.22","v0.0.21","v0.0.20","v0.0.18","v0.0.16","v0.0.15","v0.0.14","v0.0.13","v0.0.12","v0.0.11","v0.0.10","v0.0.9","v0.0.8","v0.0.7","v0.0.6","0.0.5","0.0.3","0.0.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-27938.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:N"}]}
