CVE-2025-26927
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 · uneditedUnrestricted Upload of File with Dangerous Type vulnerability in LiquidThemes AI Hub aihub allows Upload a Web Shell to a Web Server.This issue affects AI Hub: from n/a through <= 1.3.7.
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 confidenceThe AI Hub theme/plugin by LiquidThemes contains an unrestricted file upload vulnerability that allows attackers to upload malicious files (web shells) to the web server without proper validation of file types or contents. This enables remote code execution upon successful exploitation.

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 AI Hub installationCheck for the AI Hub theme or plugin files in the WordPress installation: look in wp-content/themes/ for 'ai-hub' or similar naming, and in wp-content/plugins/ for AI Hub plugin files. Inspect theme/plugin metadata files (style.css for themes, main plugin file) for 'AI Hub' or 'LiquidThemes' identification.Affected if AI Hub theme or plugin is present in the WordPress installation
-
Check installed versionLocate the version number in the theme's style.css header or the plugin's main PHP file header (Plugin Name, Version, Author, etc.). Compare this version against official LiquidThemes release notes or changelog for the affected version range.Affected if The installed version falls within the vulnerable version range published by LiquidThemes
-
Verify file upload functionality existsLocate upload-related code in the theme/plugin PHP files: search for 'upload', 'wp_handle_upload', 'move_uploaded_file', '$_FILES', or form handlers that process file uploads. Check if any theme/plugin pages contain file upload forms.Affected if File upload functionality provided by AI Hub is present and accessible
-
Inspect upload validation logicExamine the upload handling code for file type/content validation: look for functions that check file extensions, MIME types, or magic bytes before saving uploaded files. Review whether the code uses allowlist validation or only relies on client-side checks.Affected if No server-side allowlist validation or magic byte verification is performed on uploaded files
-
Check upload directory configurationExamine the theme/plugin configuration and server settings to determine where uploaded files are stored. Verify if the upload directory is within the web root and whether script execution is allowed in that directory.Affected if Uploaded files are stored inside the web-accessible directory with script execution enabled
The environment is affected if AI Hub by LiquidThemes is installed with a vulnerable version, contains an active file upload feature, and lacks proper server-side file type validation with safe storage configuration.

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 dataImplement strict allowlist-based file type validation, verify file magic bytes, restrict upload directories outside web root, and disable script execution in upload directories.
