CVE-2026-28118
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 axiomthemes Welldone welldone allows PHP Local File Inclusion.This issue affects Welldone: from n/a through <= 2.4.
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 · moderate confidenceThe Welldone theme by axiomthemes contains a PHP Local File Inclusion (LFI) vulnerability where user-supplied input is not properly validated before being used in include/require statements. This allows attackers to read sensitive local files and potentially execute arbitrary code if they can control included files.

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 Welldone theme installationSearch the web server for files belonging to the Welldone theme (look for theme directory named 'welldone' or similar, check theme configuration files like style.css which typically contains theme metadata)Affected if Welldone theme is present on the server
-
Identify Welldone theme versionOpen the theme's style.css or theme.json file and locate the version field in the theme header commentAffected if Version is at or below the vulnerable version range (compare against any known patched version)
-
Find include/require statements using user inputSearch PHP files in the theme directory for patterns like 'include($_GET', 'require($_POST', 'include($' followed by any variable that could contain user input, or direct use of $_GET, $_REQUEST, $_POST in include/require statementsAffected if Any include or require statement uses unsanitized user-supplied input (e.g., $_GET, $_POST, $_REQUEST variables) directly in the path
-
Verify user input reaches file inclusionExamine the identified vulnerable include/require code paths to confirm that user parameters can be passed without validation (check for absence of basename(), realpath(), or allowlist validation before the include/require)Affected if User-controllable parameters are directly used in file inclusion without validation or sanitization
You are affected if the Welldone theme is installed with a vulnerable version AND contains PHP include/require statements that use unsanitized user input from request parameters.

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 whitelist approaches or basename() functions to ensure only allowed files can be included; avoid passing user input directly to include/require statements.
