CVE-2026-22378
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 AncoraThemes Blabber blabber allows PHP Local File Inclusion.This issue affects Blabber: from n/a through <= 1.7.0.
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 confidenceA PHP Local File Inclusion vulnerability exists in the AncoraThemes Blabber theme (versions up to 1.7.0) where the application uses user-controlled input in include/require statements without proper validation, allowing attackers to include arbitrary PHP files from the local filesystem.

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.
-
Locate Blabber theme and determine versionNavigate to the WordPress themes directory (wp-content/themes/blabber) and open style.css or theme.json to read the Version field in the theme headerAffected if The theme version is 1.7.0 or lower, or if the version field cannot be found and the theme is confirmed as Blabber from AncoraThemes
-
Identify PHP files containing file inclusion functionsSearch the theme directory for PHP files using commands like 'grep -rn "include\|require" --include="*.php"' or manually inspect core template files (index.php, functions.php, single.php, page.php) for include/require/require_once/include_once statementsAffected if The theme contains PHP files with inclusion functions (include, require, include_once, require_once)
-
Check if user input controls the inclusion pathSearch for patterns where $_GET, $_POST, $_REQUEST, or similar superglobals are used as the path argument in inclusion functions, for example: include($_GET['file']); or require($_REQUEST['template']);Affected if User-supplied input from query parameters, form data, or cookies is used directly in include/require statements without sanitization or validation
-
Verify the vulnerable code is publicly accessibleDetermine if the file containing the vulnerable include/require is loaded during normal page requests. Test by attempting to trigger the file inclusion via URL parameters (e.g., ?file=../../../wp-config.php) to confirm the vulnerability is exploitableAffected if The vulnerable code can be reached via HTTP requests without authentication, allowing an attacker to supply arbitrary file paths
You are affected if the Blabber theme version is 1.7.0 or lower AND your theme files contain PHP include/require statements that use unsanitized user input to determine which files to load, and this code is accessible via web requests.

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 dataUpgrade to a patched version of Blabber if available, or implement strict input validation and allowlist-based file inclusion to prevent path traversal.
