Published: 14 March 2025
Summary
CVE-2024-13824 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Potenzaglobalsolutions Ciyashop. 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 24.9% 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-2024-13824 is a PHP Object Injection vulnerability (CWE-502) affecting the CiyaShop - Multipurpose WooCommerce Theme for WordPress in all versions up to and including 4.19.0. The issue arises from deserialization of untrusted input in the 'add_ciyashop_wishlist' and 'ciyashop_get_compare' functions, enabling unauthenticated attackers to inject a PHP Object. The vulnerability 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), indicating critical severity due to its network accessibility and lack of prerequisites.
Unauthenticated attackers can exploit this vulnerability remotely by supplying malicious input to the affected functions. While no known Property-Oriented Programming (POP) chain exists within the vulnerable theme itself, making it non-exploitable in isolation, the presence of a POP chain from another installed plugin or theme could enable severe impacts. Depending on the chain, attackers might delete arbitrary files, retrieve sensitive data, or execute arbitrary code on the target system.
Advisories from Wordfence and the theme's changelog on ThemeForest provide further details on mitigation. Security practitioners should review these sources—specifically https://www.wordfence.com/threat-intel/vulnerabilities/id/b69c86f4-d81d-4e14-baff-3402008bb9c6?source=cve and https://themeforest.net/item/ciyashop-responsive-multipurpose-woocommerce-wordpress-theme/22055376#item-description__changelog—for patch information, recommending updates to versions beyond 4.19.0 where the deserialization flaw is addressed.

Vulnerability details
The CiyaShop - Multipurpose WooCommerce Theme theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.19.0 via deserialization of untrusted input in the 'add_ciyashop_wishlist' and 'ciyashop_get_compare' functions. This makes it possible for unauthenticated…

attackers 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.

Mitigating Controls (NIST 800-53 r5) AI
Directly remediates the PHP object injection vulnerability by requiring timely patching of the affected CiyaShop theme versions up to 4.19.0.
Prevents unauthenticated attackers from injecting malicious PHP objects by validating untrusted inputs to the deserialization functions 'add_ciyashop_wishlist' and 'ciyashop_get_compare'.
Reduces exploitation risk by enforcing restrictions on user-installed plugins and themes that could supply the POP chain needed to escalate the object injection to arbitrary code execution or file operations.
