CVE-2025-52724 is a critical security vulnerability classified under CWE-502, which pertains to the deserialization of untrusted data. This vulnerability affects the BoldThemes Amwerk product, specifically versions up to and including 1.2.0. Deserialization vulnerabilities occur when an application deserializes data from untrusted sources without sufficient validation or sanitization, allowing attackers to manipulate serialized objects to inject malicious payloads. In this case, the vulnerability enables object injection, which can lead to remote code execution, privilege escalation, or other severe impacts on the affected system. The CVSS v3.1 base score is 9.8, indicating a critical severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The scope is unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). There are no known exploits in the wild at the time of publication, and no patches have been linked yet, which suggests that organizations using Amwerk should urgently monitor for updates and apply mitigations. The vulnerability allows attackers to send crafted serialized data over the network to the vulnerable Amwerk application, potentially leading to full system compromise without authentication or user interaction. This makes it a highly critical threat, especially for web-facing instances of Amwerk.

For European organizations using BoldThemes Amwerk, this vulnerability poses a significant risk. Given the critical nature of the flaw, attackers could remotely execute arbitrary code, leading to data breaches, service disruptions, or complete system takeovers. Confidentiality breaches could expose sensitive customer or business data, while integrity violations might allow attackers to alter website content or backend configurations. Availability impacts could result in denial of service or ransomware deployment. Since Amwerk is a theme/product used in web environments, organizations in sectors such as e-commerce, media, and professional services are particularly vulnerable. The lack of required privileges or user interaction means that attackers can exploit this vulnerability remotely and autonomously, increasing the likelihood of automated attacks and widespread exploitation once exploit code becomes available. The absence of patches at the time of disclosure further elevates the risk, as organizations must rely on temporary mitigations. This vulnerability could also be leveraged as an entry point for lateral movement within corporate networks, amplifying its impact.

European organizations should immediately audit their use of BoldThemes Amwerk to identify affected versions (up to 1.2.0). Until an official patch is released, organizations should implement network-level protections such as Web Application Firewalls (WAFs) with custom rules to detect and block suspicious serialized payloads or unusual POST requests targeting Amwerk endpoints. Disabling or restricting deserialization functionality where possible, or applying input validation and sanitization on all serialized data inputs, can reduce risk. Organizations should also monitor network traffic and application logs for anomalous activity indicative of exploitation attempts. Segmentation of web servers and limiting their access to critical backend systems can contain potential breaches. Regular backups and incident response plans should be updated to prepare for possible exploitation. Once a patch is available, it must be applied promptly. Additionally, engaging with BoldThemes support for guidance and subscribing to vulnerability advisories will help maintain situational awareness.
