CVE-2025-58662 is a high-severity vulnerability classified under CWE-502, which involves the deserialization of untrusted data in the Awesome Support plugin by awesomesupport. This vulnerability allows for object injection attacks, where an attacker can manipulate serialized data inputs to inject malicious objects during the deserialization process. The affected product versions include Awesome Support up to version 6.3.4, although the exact range of affected versions is not fully specified (noted as 'n/a' through 6.3.4). The vulnerability has a CVSS v3.1 base score of 7.2, indicating a high level of risk. The CVSS vector (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) shows that the attack can be performed remotely over the network with low attack complexity, but requires high privileges (PR:H) on the system and no user interaction. The impact covers confidentiality, integrity, and availability, all rated high, meaning successful exploitation could lead to full compromise of the affected system. Deserialization vulnerabilities typically allow attackers to execute arbitrary code, escalate privileges, or cause denial of service by injecting crafted serialized objects that the application processes insecurely. Since Awesome Support is a WordPress-based helpdesk and support ticketing plugin widely used by organizations to manage customer support, exploitation could lead to unauthorized access to sensitive customer data, manipulation or deletion of support tickets, and potential lateral movement within the network. No known exploits are reported in the wild yet, and no patches are currently linked, indicating that organizations should prioritize monitoring and mitigation efforts.

For European organizations, the impact of this vulnerability is significant, especially for those relying on Awesome Support for customer service and support operations. Exploitation could lead to exposure of sensitive personal data protected under GDPR, resulting in legal and regulatory consequences including fines and reputational damage. The compromise of support systems could disrupt business continuity, degrade customer trust, and provide attackers with a foothold to pivot into other internal systems. Given the high confidentiality, integrity, and availability impacts, organizations could face data breaches, service outages, and unauthorized modifications to support records. This is particularly critical for sectors such as finance, healthcare, and government agencies in Europe that handle sensitive information and require strict compliance with data protection laws. The requirement for high privileges to exploit the vulnerability suggests that insider threats or attackers who have already gained some level of access could leverage this flaw to escalate privileges further and fully compromise the system.

To mitigate this vulnerability, European organizations should: 1) Immediately audit their use of the Awesome Support plugin and identify all instances and versions deployed. 2) Apply any available patches or updates from the vendor as soon as they are released. In the absence of official patches, consider temporarily disabling or uninstalling the plugin to eliminate the attack surface. 3) Restrict access to the WordPress admin interface and plugin management to only trusted administrators using strong authentication methods such as multi-factor authentication (MFA). 4) Implement strict input validation and sanitization controls where possible to prevent malicious serialized data from being processed. 5) Monitor logs for unusual activity related to deserialization processes or unexpected object injections. 6) Conduct regular security assessments and penetration testing focusing on deserialization vulnerabilities. 7) Educate administrators and developers about the risks of insecure deserialization and encourage secure coding practices. 8) Employ web application firewalls (WAFs) with rules designed to detect and block suspicious serialized payloads targeting this vulnerability. 9) Limit the privileges of accounts that interact with the plugin to reduce the impact of potential exploitation.
