Deserialization of Untrusted Data vulnerability in AncoraThemes Beelove beelove allows Object Injection.This issue affects Beelove: from n/a through <= 1.2.6.

AnalysisAI

A PHP Object Injection vulnerability exists in AncoraThemes Beelove WordPress theme through version 1.2.6, allowing attackers to inject and deserialize untrusted objects. This insecure deserialization flaw (CWE-502) enables object injection attacks that could lead to remote code execution or other malicious actions depending on available gadget chains in the WordPress environment. No CVSS score, EPSS data, or KEV confirmation is currently available; however, the vulnerability has been documented by Patchstack and assigned ENISA EUVD ID EUVD-2026-15515, indicating it is tracked in official vulnerability databases.

Technical ContextAI

The vulnerability stems from unsafe deserialization of untrusted data in PHP code within the Beelove theme (CPE: cpe:2.3:a:ancorathemes:beelove:*:*:*:*:*:*:*:*). CWE-502 (Deserialization of Untrusted Data) describes the root cause: when PHP's unserialize() function or similar deserialization mechanisms process attacker-controlled input without proper validation, they can instantiate arbitrary object types. In WordPress contexts, this often exploits object gadget chains—sequences of existing class methods and properties—to achieve code execution without directly calling eval(). The Beelove theme likely deserializes user-supplied data (possibly from POST parameters, cookies, or database records) without sufficient sanitization, allowing an unauthenticated or low-privileged attacker to craft malicious serialized PHP objects.

RemediationAI

Update the AncoraThemes Beelove theme immediately to a version newer than 1.2.6 once a patch is released by the vendor. Until an official patch is available, consider temporarily deactivating the theme or restricting access to administrative functions and forms that may process serialized data. If continued use is necessary, implement Web Application Firewall (WAF) rules to block requests containing serialized PHP objects (patterns like 'O:[0-9]+:' or 'a:[0-9]+:{'), monitor logs for suspicious deserialization attempts, and restrict theme functionality to trusted users only. Consult Patchstack's advisory and AncoraThemes' official channels for patch availability and apply updates as soon as released.
