CVE-2024-13889: CWE-502 Deserialization of Untrusted Data in wordpressdotorg WordPress Importer
The WordPress Importer plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 0.8.3 via deserialization of untrusted input in the 'maybe_unserialize' function. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
AI Analysis
Technical Summary
CVE-2024-13889 is a PHP Object Injection vulnerability in the WordPress Importer plugin for WordPress, affecting all versions up to 0.8.3. It arises from unsafe deserialization in the 'maybe_unserialize' function, allowing authenticated users with Administrator privileges to inject PHP objects. The vulnerability itself does not directly lead to exploitation unless a gadget POP chain is present in other installed plugins or themes, which could enable actions such as arbitrary file deletion, sensitive data retrieval, or code execution. The CVSS 3.1 base score is 7.2, indicating high severity. No patch or remediation details are currently available, and no exploits have been observed in the wild.
Potential Impact
An attacker with Administrator-level access can exploit this vulnerability only if a gadget POP chain exists in other installed plugins or themes. Potential impacts include arbitrary file deletion, sensitive data exposure, and remote code execution depending on the POP chain. Without such a POP chain, the vulnerability does not lead to impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, administrators should monitor for updates from the WordPress Importer plugin maintainers. Restrict Administrator access to trusted users and review installed plugins and themes for known gadget POP chains to reduce risk.
