Description

CodeIgniter4's ImageMagick Handler has Command Injection Vulnerability

Impact

This vulnerability affects applications that:

  • Use the ImageMagick handler for image processing (imagick as the image library)
  • AND either:
  • Allow file uploads with user-controlled filenames and process uploaded images using the resize() method
  • OR use the text() method with user-controlled text content or options

An attacker can:

  • Upload a file with a malicious filename containing shell metacharacters that get executed when the image is processed
  • OR provide malicious text content or options that get executed when adding text to images

Patches

Upgrade to v4.6.2 or later.

Workarounds

  • Switch to the GD image handler (gd, the default handler), which is not affected by either vulnerability
  • For file upload scenarios: Instead of using user-provided filenames, generate random names to eliminate the attack vector with getRandomName() when using the move() method, or use the store() method, which automatically generates safe filenames
  • For text operations: If you must use ImageMagick with user-controlled text, sanitize the input to only allow safe characters: preg_replace('/[^a-zA-Z0-9\s.,!?-]/', '', $text) and validate/restrict text options

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: High — total loss, or loss the attacker controls.

Weakness class

CVE-2025-54418 is classified as CWE-78: OS Command Injection. Untrusted input reaches a shell command without neutralisation, so an attacker can run arbitrary operating system commands.
