Injection requires the elevated admin.pages/api.pages.write permission so PR:H; network-reachable simple callable sink gives AC:L, and full code execution yields C/I/A High with no scope change.

Grav 2.0.4 (fixed in 2.0.7) contains a remote code execution vulnerability in Blueprint::dynamicData() (system/src/Grav/Common/Data/Blueprint.php), which passes a Class::method callable string and its arguments directly to call_user_func_array() without any allowlist. Because the form plugin routes page frontmatter through this path, an authenticated account with the admin.pages (or api.pages.write) permission can plant a malicious callable directive in a page. The command then executes as the web-server user whenever anyone - including an unauthenticated visitor - accesses the page.

Remote code execution in Grav CMS 2.0.4 (fixed in 2.0.7) lets an authenticated user holding the admin.pages or api.pages.write permission plant a malicious Class::method callable directive in page frontmatter, which Blueprint::dynamicData() feeds unfiltered into call_user_func_array(). The injected command then executes as the web-server user for any subsequent visitor to the page, including unauthenticated ones. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated account possessing the Grav admin.pages permission or the api.pages.write permission to inject a malicious 'Class::method' callable directive into a page's frontmatter; this privileged write is the essential prerequisite and the primary limiting factor. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-assigned CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H, base 9.3) rates this as critical and unauthenticated, but that PR:N reflects only the trigger stage - an unauthenticated visitor rendering the poisoned page - not the injection stage, which requires an authenticated account with the admin.pages or api.pages.write permission. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with a low-trust editor account (holding admin.pages or api.pages.write) creates or edits a page and embeds a malicious Class::method callable and arguments in the frontmatter. The next time anyone loads that page - the attacker themselves or an unauthenticated site visitor - Blueprint::dynamicData() invokes the callable via call_user_func_array(), executing the attacker's command as the web-server user. … |
| Remediation | Vendor-released patch: upgrade to Grav 2.0.7 or later, which introduces restrictions on the callable resolution path; this is the primary and recommended fix, per advisory GHSA-fj2p-qj2f-74v5 (https://github.com/getgrav/grav/security/advisories/GHSA-fj2p-qj2f-74v5). … Detailed patch versions, workarounds, and compensating controls in full report. |
