CVE-2026-24981
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 · uneditedDeserialization of Untrusted Data vulnerability in NooTheme Visionary Core noo-visionary-core allows Object Injection.This issue affects Visionary Core: from n/a through <= 1.4.9.
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 confidenceThis is a PHP Object Injection vulnerability in the NooTheme Visionary Core WordPress theme. The vulnerability occurs when the application deserializes untrusted data (likely through PHP's unserialize() function) without proper validation, potentially allowing attackers to execute arbitrary code by crafting malicious serialized objects.

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 the Visionary Core theme installationCheck your WordPress themes directory (wp-content/themes/) for a folder named 'visionary-core', 'visionary', or similar NooTheme theme names. If using a child theme, also check for parent theme references.Affected if The Visionary Core theme folder exists in your WordPress installation
-
Identify the installed theme versionOpen the theme's style.css file (typically at wp-content/themes/[visionary-folder]/style.css) and look for the 'Version:' header in the file comments. Alternatively, check for a version.php or version.json file in the theme folder.Affected if The version header shows a version number; compare this to any patched version if known, or assume all versions may be affected if no patch information is available
-
Search for deserialization code pathsUse grep or a file search to scan the theme folder for PHP files containing 'unserialize(', 'base64_decode' combined with unserialize, or similar data parsing functions that may handle external input.Affected if Files containing unserialize() calls are found that process request parameters, POST data, or cookie values without validation
-
Identify input sources feeding unserializeExamine any identified unserialize() calls in detail. Look for $_GET, $_POST, $_COOKIE, or file_get_contents('php://input') being passed directly to unserialize() or after minimal encoding like base64.Affected if Untrusted input sources (request parameters, user data) are passed to unserialize() without validation or sanitization
-
Check for exposed AJAX or admin endpointsReview the theme's functions.php and any AJAX handlers for endpoints that may accept and deserialize payload data, especially those accessible to unauthenticated users.Affected if AJAX or other public-facing endpoints exist that process serialized data from users
Your environment is affected if the Visionary Core theme is installed and contains code that deserializes untrusted input from users without proper validation.
Generated from the published advisory. Verify against your own 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 dataUpgrade to a patched version of Visionary Core if available. If no patch exists, identify and disable the vulnerable deserialization code path, or implement input validation/waf rules to block malicious serialized payloads.
