CVE-2020-13458
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue was discovered in the Image Resizer plugin before 2.0.9 for Craft CMS. There are CSRF issues with the log-clear controller action.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceCross-Site Request Forgery (CSRF) vulnerability in the Image Resizer plugin for Craft CMS allows attackers to trigger the log-clear controller action without proper CSRF token validation, potentially allowing unauthorized log clearing via malicious requests.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Image Resizer plugin is installedAccess your Craft CMS admin panel and navigate to Settings > Plugins, or inspect your craft/plugins or vendor/verbb/image-resizer directory to verify the Image Resizer plugin is present in the installation.Affected if The plugin is not listed or the directory does not exist, then you are not affected.
-
Identify installed Image Resizer versionIn Craft CMS admin panel, go to Settings > Plugins and click on the Image Resizer entry to view its version number. Alternatively, check the composer.json file in vendor/verbb/image-resizer for the installed version.Affected if The installed version is lower than 2.0.9, indicating you are running a vulnerable version.
-
Verify Craft CMS versionNavigate to Settings > General in your Craft CMS admin panel to confirm the CMS version. The Image Resizer plugin runs on top of Craft CMS.Affected if This step confirms the environment context; the vulnerability exists regardless of Craft CMS version, but ensure your Craft installation is also up to date.
-
Check if log-clear action is accessibleAttempt to access the log-clear endpoint directly or inspect your routes configuration. The vulnerable endpoint is typically at /actions/image-resizer/logs/clear or similar paths under the image-resizer controller.Affected if The endpoint responds without requiring CSRF token validation, confirming the vulnerability is exploitable in your environment.
-
Review CSRF token configurationIn your Craft CMS general settings, verify whether CSRF protection is enabled. The vulnerability exists because the plugin does not validate CSRF tokens, so even if CSRF is enabled in Craft, the plugin may not be using it properly.Affected if CSRF protection is enabled in Craft but the Image Resizer plugin does not implement token validation for the log-clear action.
You are affected if the Verbb Image Resizer plugin is installed with a version lower than 2.0.9 and the log-clear functionality is accessible without CSRF token validation.
