ImageMagick: Incorrect Behavior Order: Authorization Before Parsing and Canonicalization

Published Updated By the CyberSecBulletin desk

CVE-2026-106579 is a high-severity incorrect behavior order: authorization before parsing and canonicalization vulnerability in ImageMagick, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected ImageMagick versions: < 6.9.13-56; >= 7.0.0, < 7.1.2-31. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.32% chance of exploitation within 30 days, which is low compared with other CVEs.

High severity with no evidence of exploitation so far.

What to do

  1. Check which version of ImageMagick you run against the affected versions below, and install the vendor's latest release.
  2. Read the advisory on github.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-31 and 6.9.13-56, a crafted image can bypass an ImageMagick security policy that uses coder as its domain, potentially allowing data prohibited by the policy to be read. This issue is fixed in versions 7.1.2-31 and 6.9.13-56.

The underlying weakness: Incorrect Behavior Order: Authorization Before Parsing and Canonicalization

If a web server does not fully parse requested URLs before it examines them for authorization, it may be possible for an attacker to bypass authorization protection.

How developers prevent this class of flaw

  • URL Inputs should be decoded and canonicalized to the application's current internal representation before being validated and processed for authorization. Make sure that your application does not decode the same input twice. Such errors could be used to bypass allowlist schemes by introducing dangerous inputs after they have been checked.
