CVE-2025-62025 is a critical security vulnerability identified in the eyecix JobSearch WordPress plugin (versions prior to 3.0.8). The issue arises from the unsafe deserialization of untrusted data, a process where serialized objects received from external sources are converted back into executable code without proper validation. This flaw enables remote attackers to craft malicious serialized payloads that, when processed by the vulnerable plugin, can lead to arbitrary code execution on the hosting server. The vulnerability requires no authentication or user interaction and can be exploited remotely over the network, making it highly dangerous. The CVSS 3.1 base score of 9.8 reflects its critical impact on confidentiality, integrity, and availability, as attackers could potentially take full control of affected systems, steal sensitive data, or disrupt services. Although no known public exploits have been reported yet, the nature of deserialization vulnerabilities and the widespread use of WordPress plugins in recruitment portals increase the risk of exploitation. The vulnerability affects all versions of JobSearch before 3.0.8, and no official patches or mitigation links have been published at the time of disclosure. Organizations using this plugin should consider immediate risk assessments and implement compensating controls to prevent exploitation.

For European organizations, the impact of CVE-2025-62025 is substantial. Many companies and recruitment agencies rely on WordPress-based job search plugins like eyecix JobSearch to manage employment listings and candidate data. Exploitation could lead to full system compromise, exposing sensitive personal data of job applicants and employees, violating GDPR and other data protection regulations. The integrity of job postings and application processes could be undermined, damaging organizational reputation and trust. Availability disruptions could interrupt recruitment operations, causing operational delays and financial losses. Given the critical severity and ease of exploitation, attackers could leverage this vulnerability for lateral movement within corporate networks or as a foothold for ransomware deployment. The lack of authentication and user interaction requirements further heightens the risk, making automated exploitation feasible. European organizations with publicly accessible WordPress sites using this plugin are particularly vulnerable to remote attacks from opportunistic or targeted threat actors.

Immediate mitigation steps include monitoring for updates from eyecix and applying patches as soon as they become available. Until a patch is released, organizations should implement strict input validation and sanitization on all data processed by the JobSearch plugin, especially any serialized data inputs. Employing web application firewalls (WAFs) with custom rules to detect and block suspicious serialized payloads can reduce exposure. Restricting access to the plugin’s endpoints via IP whitelisting or VPNs can limit attack surface. Regularly auditing WordPress plugins and removing unused or unsupported ones reduces risk. Additionally, isolating WordPress instances in segmented network zones and enforcing least privilege principles on web server accounts can limit potential damage. Organizations should also enhance logging and monitoring to detect anomalous deserialization attempts and prepare incident response plans specific to web application compromises. Finally, educating development and security teams about secure deserialization practices will help prevent similar vulnerabilities in the future.
