Arbitrary Code Injection

Overview getgrav/grav is a Modern, Crazy Fast, Ridiculously Easy and Amazingly Powerful Flat-File CMS. Affected versions of this package are vulnerable to Arbitrary Code Injection via the dynamicData function. An attacker can execute arbitrary code by planting a malicious callable directive in a...

CVE-2026-65008

Grav 2.0.4 contains a remote code execution vulnerability in Blueprint::dynamicData(), where a Class::method callable string and arguments are passed to call_user_func_array() without an allowlist. The form plugin routes page frontmatter through this path, allowing an authenticated user with admi...

Code Injection

@prompty/core is vulnerable to Code Injection. The vulnerability is due to the use of gray-matter with executable JavaScript frontmatter enabled, which allows an attacker to execute arbitrary JavaScript by supplying a malicious .prompty file...
