CVE-2025-69099
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 fuelthemes North north-wp allows Object Injection.This issue affects North: from n/a through <= 5.7.5.
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 North WordPress theme stemming from insecure use of PHP's unserialize() function on untrusted data. Attackers can craft malicious serialized PHP objects to trigger arbitrary code execution, file operations, or SQL injection via magic method gadget chains present in the theme or associated libraries.

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.
-
Verify North theme is installedNavigate to Appearance > Themes in WordPress admin, or inspect /wp-content/themes/ directory, to confirm the North theme is present.Affected if North theme is installed and activated on the WordPress site
-
Identify installed theme versionOpen the style.css file within the theme directory (/wp-content/themes/north/) and locate the Version: header in the file comments.Affected if The version number listed is 5.7.5 or lower, or if no version is declared and the theme has not been patched
-
Confirm vulnerability precondition existsInspect theme files (particularly functions.php and any files handling request parameters) for usage of unserialize() on untrusted input such as $_GET, $_POST, or $_COOKIE values.Affected if Code contains unserialize() calls processing user-supplied data without prior validation
-
Check for exposed deserialization entry pointsReview theme AJAX handlers and action hooks for functions that accept and deserialize serialized data from request parameters.Affected if AJAX or action handlers accept and unserialize data from $_REQUEST, $_POST, or $_GET parameters
A site is affected if it runs the North theme version 5.7.5 or lower and the theme code contains unserialize() calls processing untrusted user input.
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 dataUpdate the North theme to the latest patched version once released. If no patch is available, identify and replace all instances of unserialize() with secure alternatives like json_decode(), and audit for available PHP object injection gadget chains in the theme and dependencies.
