{"id":"CVE-2026-61842","summary":"Grav: Twig sandbox config exfiltration via grav.offsetGet + dump filter (CVE-2026-44738 bypass)","details":"Grav is a file-based Web platform. Prior to 2.0.2, the Grav Twig content sandbox permits grav.offsetGet('config') to return the raw configuration object and permits json_encode, print_r, yaml_encode, and string filters to serialize that object without passing through GravSecurityPolicy::checkMethodAllowed. A user with page-author permissions can render sandboxed content that exposes plugins.* configuration secrets, including SMTP credentials, API keys, and plugin database credentials. This issue is fixed in version 2.0.2.","aliases":["CVE-2026-61450","GHSA-mc5q-6hpj-rp7j"],"modified":"2026-09-11T03:30:21.879484870Z","published":"2026-08-19T15:23:27.038Z","database_specific":{"cwe_ids":["CWE-200"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61842.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/getgrav/grav/releases/tag/2.0.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61842.json"},{"type":"ADVISORY","url":"https://github.com/getgrav/grav/security/advisories/GHSA-mc5q-6hpj-rp7j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61842"},{"type":"FIX","url":"https://github.com/getgrav/grav/commit/7efe70574e4cf01a251318478c13673029e93eb6"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/getgrav/grav","events":[{"introduced":"0"},{"fixed":"7efe70574e4cf01a251318478c13673029e93eb6"},{"fixed":"cc9971b6efa43bc797d3c593f69020a6b7335817"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"2.0.2"}]}}],"versions":["2.0.1","2.0.0","1.7.53","1.7.52","1.7.51","1.7.39.1","1.7.39","1.7.38","1.7.37.1","1.7.37","1.7.36","1.7.35","1.7.34","1.7.33","1.7.32","1.7.31","1.7.30","1.7.29.1","1.7.29","1.7.28","1.7.27.1","1.7.27","1.7.26.1","1.7.26","1.7.25","1.7.24","1.7.23","1.7.22","1.7.21","1.7.20","1.7.19","1.7.18","1.7.17","1.7.16","1.7.15","1.7.14","1.7.13","1.7.12","1.7.10","1.7.9","1.7.8","1.7.7","1.7.6","1.7.5","1.7.4","1.7.3","1.7.1","1.7.0","1.7.0-rc.20","1.7.0-rc.19","1.7.0-rc.18","1.7.0-rc.17","1.7.0-rc.15","1.7.0-rc.14","1.7.0-rc.13","1.7.0-rc.12","1.7.0-rc.10","1.7.0-rc.9","1.7.0-rc.8","1.7.0-rc.7","1.7.0-rc.6","1.7.0-rc.5","1.7.0-rc.4","1.7.0-rc.3","1.7.0-rc.2","1.7.0-rc.1","1.7.0-beta.10","1.7.0-beta.9","1.7.0-beta.8","1.7.0-beta.7","1.7.0-beta.6","1.7.0-beta.5","1.7.0-beta.4","1.7.0-beta.3","1.7.0-beta.2","1.7.0-beta.1","1.6.0-rc.4","1.6.0-rc.3","1.6.0-rc.2","1.6.0-rc.1","1.6.0-beta.8","1.6.0-beta.7","1.6.0-beta.6","1.6.0-beta.5","1.6.0-beta.2","1.6.0-beta.1","1.5.0-rc.1","1.5.0-beta.2","1.5.0-beta.1","1.3.0-rc.5","1.3.0-rc.4","1.3.0-rc.3","1.3.0-rc.1","1.2.0-rc.3","1.2.0-rc.2","1.2.0-rc.1","1.1.9-rc.3","1.1.9-rc.2","1.1.9-rc.1","1.1.0-rc.3","1.1.0-rc.2","1.1.0-rc.1","1.1.0-beta.5","1.1.0-beta.4","1.1.0-beta.3","1.1.0-beta.2","1.1.0-beta.1","0.9.19","0.9.18","0.9.17","0.9.16","0.9.15","0.9.14","0.9.13","0.9.12","0.9.11","0.9.10","0.9.9","0.9.8","0.9.7","0.9.6","0.9.5","0.9.4","0.9.3","0.9.2","0.9.0","0.8.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-61842.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:N/A:N"}]}
