{"id":"CVE-2026-85604","state":"PUBLISHED","title":"Grav before 2.0.18 Remote Code Execution via sort filter","description":"Grav before 2.0.18 (affected versions <= 2.0.17) contains a remote code execution vulnerability in the Twig sort filter. The sortFunc wrapper in GravExtension.php hardcodes Twig's isSandboxed argument to false, so unlike |map/|filter/|reduce, |sort accepts a plain function name inside the sandbox; the remaining denylist misses spl_autoload, which performs a PHP include. An authenticated user with only page-write rights (admin.pages or api.pages.write) can supply a crafted payload (e.g., via form frontmatter rendered by the Email plugin) that invokes spl_autoload through the sort filter, resulting in arbitrary PHP execution as the web server user.","publishedAt":"2026-09-04T11:30:05.453Z","updatedAt":"2026-09-08T16:28:18.434Z","severity":{"score":8.7,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["getgrav grav"],"affected":[{"vendor":"getgrav","product":"grav","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"2.0.18","versionType":"semver"},{"version":"2.0.18","status":"unaffected","versionType":"semver"}]}],"references":["https://github.com/getgrav/grav/security/advisories/GHSA-p6qj-p5m7-f62h","https://www.vulncheck.com/advisories/grav-before-2.0.19-remote-code-execution-via-sort-filter"],"weaknesses":["CWE-94"],"ingestedAt":"2026-10-29T20:13:15.269Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/85xxx/CVE-2026-85604.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-85604","state":"PUBLISHED","datePublished":"2026-09-04T11:30:05.453Z","dateUpdated":"2026-09-08T16:28:18.434Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-09-04T11:00:28.731Z"},"containers":{"cna":{"title":"Grav before 2.0.18 Remote Code Execution via sort filter","descriptions":[{"lang":"en","value":"Grav before 2.0.18 (affected versions <= 2.0.17) contains a remote code execution vulnerability in the Twig sort filter.
