CVE-2024-0668: Advanced Database Cleaner <= 3.1.3 - Authenticated(Administrator+) PHP Object Injection via process_bulk_action

The Advanced Database Cleaner plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.1.3 via deserialization of untrusted input in the 'process_bulk_action' function. This makes it possible for authenticated attacker, with administrator access and above, 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.

Security readout for executives and security teams

Plain-English summary

This issue affects the WordPress Advanced Database Cleaner plugin through version 3.1.3. An attacker already holding Administrator-level access could send unsafe serialized data that PHP may deserialize. The plugin itself lacks a known usable gadget chain, but another installed plugin or theme could make impact much worse.

Executive priority

Treat this as a moderate-priority WordPress maintenance item. It is unlikely to be the first entry point because Administrator access is required, but it can amplify damage if an admin account is compromised or abused.

Technical view

CVE-2024-0668 is CWE-502 PHP object injection in process_bulk_action, with CVSS 6.6. Exploitation requires network access and high privileges, with high attack complexity. Sources state no POP chain exists in the vulnerable plugin, but a chain from another plugin or theme could enable file deletion, sensitive data access, or code execution.

Likely exposure

Exposure is limited to WordPress sites running Advanced Database Cleaner version 3.1.3 or earlier where an attacker has Administrator or higher access. Risk increases on sites with many third-party plugins or themes that may introduce a compatible POP chain.

Exploitation context

The source bundle does not show active exploitation, and the CVE is not listed as KEV. Practical exploitation requires privileged access and a suitable object chain outside the vulnerable plugin, so this is mainly a post-compromise or malicious-admin risk.

Researcher notes

Key uncertainty is the presence of a usable POP chain in the target environment. The vulnerable plugin reportedly has none itself, so validation should focus on version exposure, admin trust boundaries, and whether other installed code changes exploitability.

Mitigation direction

  • Update Advanced Database Cleaner to a vendor-supported release newer than 3.1.3.
  • If no fixed release is available, disable or remove the plugin pending vendor guidance.
  • Restrict Administrator-level WordPress accounts to trusted users only.
  • Review installed plugins and themes for unnecessary code that could add deserialization risk.
  • Monitor Wordfence and WordPress plugin guidance for confirmed remediation details.

Validation and detection

  • Inventory WordPress sites for Advanced Database Cleaner versions 3.1.3 or earlier.
  • Confirm whether any untrusted or stale accounts have Administrator-level access.
  • Review plugin update history and the referenced WordPress changeset for remediation evidence.
  • Check admin activity logs for unexpected database-cleaning bulk actions.
  • Document any co-installed plugins or themes that increase PHP object injection impact.
