CVE-2026-112772 — Craft CMS 5.0.0 before 5.11.0 RCE via Asset::getMimeType Transform Injection

Craft CMS from 5.0.0 before 5.11.0 contains a remote code execution vulnerability that allows authenticated Control Panel users to escape the Twig sandbox via Asset::getMimeType transforms. Attackers can supply 'as' or 'on' keys passed unfiltered to Craft::createObject, attaching malicious behaviors or event handlers that execute code as the web user.

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 (Craftcms Cms).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (injection), errors and authentication anomalies.
