CVE-2026-27081
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 · uneditedImproper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in Mikado-Themes Rosebud rosebud allows PHP Local File Inclusion.This issue affects Rosebud: from n/a through <= 1.4.
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 · high confidenceThis is a PHP Local File Inclusion (LFI) vulnerability in the Mikado Themes Rosebud theme. The application fails to properly validate filenames used in include/require statements, allowing attackers to manipulate the filename parameter to include arbitrary local PHP files from the server, potentially exposing sensitive data or achieving code execution.

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 if Mikado Themes Rosebud theme is installedLook for theme directory files such as header.php, footer.php, or style.css in wp-content/themes/rosebud/ or similar paths. Check for theme name declaration in style.css metadata.Affected if The Mikado Themes Rosebud theme is present on the server.
-
Determine the installed theme versionOpen style.css in the theme directory and locate the 'Version:' field in the theme header comment. Compare this version against any known affected version range.Affected if The theme version matches or falls within an affected version range if such ranges become available.
-
Search for vulnerable include/require patternsGrep the theme PHP files for patterns like 'include($_GET', 'require($_GET', 'include($_POST', 'require($_POST', or similar where user-supplied superglobals are used directly in include/require statements without sanitization.Affected if Code exists that uses $_GET, $_POST, or other user input directly in include or require statements without validation.
-
Identify the vulnerable parameterExamine any identified include/require patterns to determine which URL parameter controls the file inclusion. Common parameter names include 'file', 'page', 'template', 'path', or 'name'.Affected if A URL parameter is used to control which file gets included without validation.
-
Test for LFI if parameter is identifiedIf a vulnerable parameter is found, attempt a safe test by including a known local file such as /etc/passwd (Linux) or C:\windows\win.ini (Windows) via the identified parameter in a test environment.Affected if The application returns contents of files outside the intended directory, confirming LFI exists.
A user is affected if the Mikado Themes Rosebud theme is installed AND contains code that directly uses user-supplied input in include/require statements without validation, allowing arbitrary file inclusion.

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 input validation using a whitelist approach for allowed files, and ensure all user-supplied parameters used in include/require statements are sanitized and validated before use.
