Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Grav CMS versions 2.0.7 through 2.0.10 (package getgrav/grav) can be made to call arbitrary public static PHP methods through blueprint dynamic-field directives, because the callable check skips any string containing "::". An attacker needs an account with page-editing rights (admin.pages, not super-admin); the source reports that such an account can use this to read server files, disclosed to anonymous visitors of the crafted page, and to create or copy files and directories under the web-server account. The fix is to upgrade to version 2.0.11.
