FlexDirectory::dynamicDataField() resolves blueprint data-*@: directives by calling call_user_func_array() on attacker-influenced input, validating only that the target is callable (is_callable()) without restricting dangerous functions such as exec, system, passthru, or shell_exec. Because FlexDirectory registers this handler for every Flex directory, it bypasses the validation added to Blueprint::dynamicData() in 2.0.7 (GHSA-fj2p-qj2f-74v5). Any authenticated user with create or update permission on any Flex-based directory (Flex Users, Flex Pages, Flex Objects, or custom Flex types) can execute arbitrary shell commands on the server."}],"problemTypes":[{"descriptions":[{"lang":"en","description":"Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection')","cweId":"CWE-470","type":"CWE"}]}],"affected":[{"vendor":"getgrav","product":"grav","defaultStatus":"unaffected","versions":[{"version":"1.7.0","status":"affected","versionType":"semver","lessThan":"2.0.9"},{"version":"2.0.9","status":"unaffected","versionType":"semver"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:getgrav:grav:*:*:*:*:*:*:*:*","versionStartIncluding":"1.7.0","versionEndExcluding":"2.0.9"}]}]}],"metrics":[{"cvssV4_0":{"Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","Safety":"NOT_DEFINED","attackComplexity":"LOW","attackRequirements":"NONE","attackVector":"NETWORK","baseScore":8.7,"baseSeverity":"HIGH","exploitMaturity":"NOT_DEFINED","privilegesRequired":"LOW","providerUrgency":"NOT_DEFINED","subAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","userInteraction":"NONE","valueDensity":"NOT_DEFINED","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0","vulnAvailabilityImpact":"HIGH","vulnConfidentialityImpact":"HIGH","vulnIntegrityImpact":"HIGH","vulnerabilityResponseEffort":"NOT_DEFINED"},"format":"CVSS"},{"cvssV3_1":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"HIGH","baseScore":8.8,"baseSeverity":"HIGH","confidentialityImpact":"HIGH","integrityImpact":"HIGH","privilegesRequired":"LOW","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"format":"CVSS"}],"references":[{"url":"https://github.com/getgrav/grav/security/advisories/GHSA-c4wf-2xxc-68qm","name":"GitHub Security Advisory (GHSA-c4wf-2xxc-68qm)","tags":["vendor-advisory"]},{"url":"https://github.com/getgrav/grav/commit/fae9e1bf2c40ce0b50d0dfce647aaa1d22f98969","name":"Patch Commit","tags":["patch"]},{"name":"VulnCheck Advisory: Grav before 2.0.9 Remote Code Execution via FlexDirectory","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/grav-before-remote-code-execution-via-flexdirectory"}],"credits":[{"lang":"en","value":"haftoe","type":"reporter"}],"x_generator":{"engine":"vulncheck-endgame"}},"adp":[{"references":[{"url":"https://github.com/getgrav/grav/security/advisories/GHSA-c4wf-2xxc-68qm","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-23T18:00:17.857895Z","id":"CVE-2026-65608","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-23T18:00:27.972Z"}}]}}
