Published: 20 February 2025
Summary
CVE-2024-13789 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Matiskiba Ravpage. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 29.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2024-13789 is a PHP Object Injection vulnerability (CWE-502) in the ravpage plugin for WordPress, affecting all versions up to and including 2.31. The flaw stems from deserialization of untrusted input via the 'paramsv2' parameter, enabling attackers to inject a PHP Object. Published on 2025-02-20, it carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
Unauthenticated attackers can exploit this vulnerability remotely by supplying crafted input to the affected parameter. While injection is possible, the ravpage plugin itself contains no known Property-Oriented Programming (POP) chain, rendering it ineffective in isolation. Impact only materializes if another plugin or theme on the target site provides a POP chain, potentially allowing arbitrary file deletion, sensitive data retrieval, or code execution based on the chain's capabilities.
Advisories reference mitigation via an update in WordPress plugin trac changeset 3258935, alongside the vulnerable code at line 24 in ravpage.php. The Wordfence threat intelligence page provides further details on the issue.

Vulnerability details
The ravpage plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.31 via deserialization of untrusted input from the 'paramsv2' parameter. This makes it possible for unauthenticated attackers to inject a PHP Object.…
more
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.

Requires timely identification, reporting, and correction of flaws such as the PHP Object Injection in the ravpage plugin via software updates as referenced in the advisory.
Directly prevents PHP Object Injection by requiring validation and sanitization of untrusted inputs like the 'paramsv2' parameter prior to deserialization.
Mitigates risk by prohibiting or restricting user-installed software such as vulnerable WordPress plugins unless approved, scanned, and monitored.
