DescriptionCVE.org

Deserialization of Untrusted Data vulnerability in themeton The Fashion - Model Agency One Page Beauty Theme allows Object Injection. This issue affects The Fashion - Model Agency One Page Beauty Theme: from n/a through 1.4.4.

AnalysisAI

Critical deserialization of untrusted data vulnerability in themeton's 'The Fashion - Model Agency One Page Beauty Theme' WordPress theme (versions up to 1.4.4) that enables object injection attacks. An unauthenticated, remote attacker can exploit this with no user interaction required to achieve complete system compromise including confidentiality, integrity, and availability breaches. The CVSS 9.8 score reflects the critical nature (network-accessible, low complexity, no privileges needed, high impact across all security properties), though real-world exploitation likelihood depends on whether public POCs exist and if the vulnerability is actively being weaponized in the wild.

Technical ContextAI

The vulnerability exists in a WordPress theme's deserialization handling (CWE-502: Deserialization of Untrusted Data). This class of vulnerability occurs when PHP's unserialize() function or similar mechanisms process untrusted input without proper validation. In WordPress theme context, this often manifests in theme settings, AJAX handlers, or REST API endpoints that accept serialized PHP objects. When an attacker crafts malicious serialized data containing gadget chains (sequences of existing PHP classes whose __wakeup() or __destruct() magic methods can be chained together), the deserialization process can trigger arbitrary code execution. The affected product is themeton's 'The Fashion - Model Agency One Page Beauty Theme' (CPE pattern would be: cpe:2.3:a:themeton:the_fashion_model_agency_one_page_beauty_theme:*:*:*:*:*:wordpress:*:*), with vulnerable versions from an unspecified baseline through 1.4.4.

RemediationAI

Patching: Update 'The Fashion - Model Agency One Page Beauty Theme' to version 1.4.5 or later (assuming patch released post-1.4.4; verify with themeton releases); priority: Immediate Workaround: If immediate patching is unavailable: (1) Disable or remove the theme if not in active use; (2) Restrict access to theme configuration/AJAX endpoints via .htaccess or WAF rules; (3) Monitor WordPress theme files for unauthorized modifications; (4) Review server logs for suspicious serialized object patterns in POST/GET requests; priority: High Detection: Monitor for POST requests containing 'O:' or 'C:' markers (PHP serialized object notation) to theme-related endpoints; audit WordPress user activity logs for unauthorized theme modifications; priority: High Architecture: Replace serialized PHP with JSON-based data exchange; implement input validation and sanitization for all deserialization points; use allowlists for deserializable classes; priority: Medium (long-term)
