CVE-2026-112780 — Grav 2.0.15 before 2.2.2 Arbitrary Static Method Call via Flex Form replace-name@

Grav from 2.0.15 before 2.2.2 contains an allowlist bypass vulnerability that allows page editors to call arbitrary public static methods by renaming Flex form fields with replace-name@. Attackers with page-edit permission can smuggle data-*@ directives past the callable check to invoke Folder::delete, Folder::move, or Utils::download, deleting directories, overwriting files, or reading files.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Getgrav Grav).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes, errors and authentication anomalies.
