## Summary

Grav, an open-source flat-file content management system, is affected in versions from 2.0.15 up to (but not including) the patched release. An attacker with page-editing permission can abuse Flex form override fields to run unauthorized server-side methods, which could delete directories, overwrite files, or read files outside the page content area.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- getgrav grav: from 2.0.15, fixed in 2.2.13

## Description

Grav 2.0.15 before 2.2.13 contains an allowlist bypass vulnerability that allows page editors to invoke arbitrary public static methods by relocating data-*@ directives with unset-name@ or integer keys. Attackers with page-edit permission can embed crafted fields in Flex form overrides in page frontmatter to call methods like Folder::delete or Utils::download, deleting directories, overwriting files, or reading files outside the page tree.
