CVE-2024-10942
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 All-in-One WP Migration and Backup plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 7.89 via deserialization of untrusted input in the 'replace_serialized_values' function. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software. 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. An administrator must export and restore a backup in order to trigger the exploit.
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 All-in-One WP Migration and Backup plugin for WordPress contains a PHP Object Injection vulnerability in the 'replace_serialized_values' function. This function deserializes untrusted input without proper validation, allowing unauthenticated attackers to inject arbitrary PHP objects. While no POP chain exists in the plugin itself, exploitation becomes critical if other installed plugins or themes provide a usable chain.

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 the All-in-One WP Migration plugin is installedNavigate to WordPress admin Dashboard > Plugins and look for 'All-in-One WP Migration' in the installed plugins listAffected if The plugin is present in the plugins list
-
Check the installed plugin versionClick on the plugin in the WordPress plugins list to view its details, or check the version in the plugin's main PHP file header commentAffected if The installed version is 7.89 or earlier (versions prior to the fix)
-
Identify if backup import functionality is accessibleCheck if the WordPress site allows backup file imports. Look for the import/upload functionality in the plugin settings or try accessing the import endpoint directlyAffected if Unauthenticated or low-privilege users can import backup files
-
Audit other plugins and themes for POP chainsReview all installed plugins and active theme for known PHP Object Injection POP chain gadgets. Check vulnerability databases and changelogs for deserialization flaws in other pluginsAffected if Any installed plugin or theme contains a usable POP chain that can be triggered via the deserialization in this plugin
A user is affected if they have All-in-One WP Migration version 7.89 or earlier installed and the backup import feature is accessible to untrusted users or other plugins with POP chains exist on the site.

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 plugin to a version beyond 7.89 when available. Additionally, audit all installed plugins and themes for potential POP chains, restrict backup import capabilities to trusted administrators only, and remove any unused plugins that could provide a POP chain.
