CVE-2024-1770
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 · uneditedThe Meta Tag Manager plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.0.2 via deserialization of untrusted input in the get_post_data function. This makes it possible for authenticated attackers, with contributor access or higher, to inject a PHP Object. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
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 confidenceThe Meta Tag Manager WordPress plugin is vulnerable to PHP Object Injection via unsafe deserialization of untrusted input in the get_post_data function. Authenticated attackers with contributor-level access or higher can inject arbitrary PHP objects. While no POP chain exists within the plugin itself, a POP chain from another installed plugin or theme could enable arbitrary file deletion, data exfiltration, or 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.
-
Verify Meta Tag Manager plugin is installedIn WordPress Admin, go to Plugins and locate Meta Tag Manager in the list, or check for the directory /wp-content/plugins/meta-tag-manager/ on the serverAffected if Plugin is present in the installation
-
Determine installed versionView the Meta Tag Manager entry in the WordPress Plugins page to read the version number, or inspect the plugin main file header in /wp-content/plugins/meta-tag-manager/meta-tag-manager.php for the 'Version' fieldAffected if Version is below 3.0.3 (versions prior to 3.0.3 contain the vulnerability)
-
Confirm authenticated access existsIn WordPress Admin, go to Users and review which accounts have Contributor-level access or higher, as this role is required to exploit the get_post_data functionAffected if At least one user account has Contributor, Author, Editor, or Administrator role
A user is affected if the Meta Tag Manager plugin is installed with a version lower than 3.0.3 and there exists at least one user with Contributor-level access or higher who could trigger the unsafe deserialization in get_post_data.

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 Meta Tag Manager plugin to version 3.0.3 or later. Until patched, limit contributor-level access and audit other installed plugins/themes for POP chain vulnerabilities.
