Deserialization of Untrusted Data vulnerability in Edge-Themes Archicon archicon allows Object Injection.This issue affects Archicon: from n/a through < 1.7.

AnalysisAI

A deserialization of untrusted data vulnerability exists in Edge-Themes Archicon WordPress theme versions prior to 1.7, allowing attackers to perform arbitrary object instantiation through object injection attacks. This vulnerability, tracked as CWE-502, enables attackers to instantiate arbitrary PHP objects during the deserialization process, potentially leading to remote code execution or other malicious outcomes depending on available gadget chains in the WordPress environment. The vulnerability was reported by Patchstack and affects all versions of Archicon below 1.7, with a patch available in version 1.7 and later.

Technical ContextAI

The vulnerability stems from unsafe deserialization of untrusted data in the Archicon WordPress theme (CPE: cpe:2.3:a:edge-themes:archicon:*:*:*:*:*:*:*:*). The root cause is classified under CWE-502 (Deserialization of Untrusted Data), a critical class of vulnerability where user-controlled input is passed to PHP's unserialize() function or similar deserialization mechanisms without proper validation. WordPress themes are particularly susceptible to this issue when they accept serialized data from query parameters, POST bodies, cookies, or stored database values without sanitization. During deserialization, PHP instantiates arbitrary objects specified in the serialized payload, and if gadget chains exist within WordPress core or installed plugins, attackers can chain object constructors and destructors to achieve code execution. The Archicon theme likely processes serialized options or theme settings without validating the data integrity or source.

RemediationAI

Immediately upgrade the Archicon WordPress theme to version 1.7 or later, which includes the patch for this deserialization vulnerability. Theme updates can be applied through the WordPress admin dashboard (Appearance > Themes > Archicon > Update) or via CLI using wp theme update archicon. For organizations unable to update immediately, implement input validation and sanitization on any user-controllable data that may be deserialized, though this is insufficient as a long-term mitigation. Additionally, reduce the attack surface by ensuring WordPress and all plugins are kept current, as gadget chains often depend on specific versions of WordPress core functions. Consider implementing Web Application Firewall (WAF) rules to detect and block serialized PHP object patterns in HTTP requests. Until patching is complete, restrict administrative access and monitor PHP error logs for object instantiation warnings. Verify the update was successful by confirming theme version 1.7 or later is active via the WordPress dashboard or wp theme list CLI command.
