CVE-2026-2560
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 · uneditedA vulnerability has been found in kalcaddle kodbox up to 1.64.05. The impacted element is the function run of the file plugins/fileThumb/lib/VideoResize.class.php of the component Media File Preview Plugin.

The vendor was contacted early about this disclosure but did not respond in any way.
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 confidenceOS command injection vulnerability in kodbox Media File Preview Plugin's VideoResize.class.php. The run function improperly handles the localFile parameter, allowing remote attackers to inject arbitrary OS commands through unsanitized input passed to system calls.

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.
-
Identify kodbox installationLocate kodbox in the web server document root or check for kodbox directories. Common paths include /var/www/html/kodbox, /www/wwwroot/kodbox, or C:\inetpub\wwwroot\kodbox depending on the operating system.Affected if kodbox software is present on the server
-
Locate the Media File Preview PluginCheck for the Media File Preview Plugin directory within the kodbox installation, typically found under plugins/ or external/plugins/. Verify the plugin folder exists and contains VideoResize.class.php.Affected if Media File Preview Plugin is installed in the kodbox environment
-
Verify the vulnerable file is presentSearch for VideoResize.class.php in the Media File Preview Plugin directory. If found, note its path and last modification timestamp for baseline comparison.Affected if VideoResize.class.php exists in the plugin directory, indicating the vulnerable component is present
-
Review for signs of compromiseExamine web server access logs and error logs for requests to the VideoResize function with suspicious characters such as ;, |, &&, or backticks in localFile parameters. Check for unexpected new files or processes on the server.Affected if Suspicious command injection patterns appear in logs or unexpected modifications exist in the kodbox directory
You are affected if kodbox with the Media File Preview Plugin is installed and VideoResize.class.php handles the localFile parameter without sanitization.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataDisable the Media File Preview Plugin until a vendor patch is released; if plugin is required, implement WAF rules to block command injection patterns in request parameters and apply network segmentation to limit exposure.
