CVE-2025-31055 is a high-severity reflected Cross-site Scripting (XSS) vulnerability identified in the WordPress plugin 'Electrician - Electrical Service' developed by vergatheme. This vulnerability arises from improper neutralization of input during web page generation, classified under CWE-79. Specifically, the plugin fails to adequately sanitize user-supplied input before reflecting it back in HTTP responses, allowing attackers to inject malicious scripts. When a victim visits a crafted URL containing the malicious payload, the injected script executes in the victim's browser context. This can lead to a range of impacts including session hijacking, defacement, redirection to malicious sites, or theft of sensitive information. The CVSS v3.1 base score is 7.1, indicating a high severity level. The vector string (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L) reveals that the attack can be launched remotely over the network without privileges, requires low attack complexity, no prior authentication, but does require user interaction (clicking a crafted link). The scope is changed (S:C), meaning the vulnerability affects resources beyond the vulnerable component, and the impact affects confidentiality, integrity, and availability to a limited extent. The vulnerability affects all versions up to 1.0 of the plugin, with no patch currently available or linked. No known exploits in the wild have been reported yet. Given the plugin's role in electrical service websites, it is likely used by small to medium enterprises in the home services sector, which may not have strong security controls, increasing risk. The reflected XSS nature means attackers need to lure users into clicking malicious links, often via phishing or social engineering. The vulnerability's presence in a WordPress plugin is significant due to WordPress's widespread use and the potential for chained attacks if combined with other vulnerabilities or weak configurations.

For European organizations, especially small and medium-sized enterprises (SMEs) operating electrical service or home improvement websites using the Electrician plugin, this vulnerability poses a tangible risk. Successful exploitation can lead to session hijacking, enabling attackers to impersonate legitimate users or administrators, potentially leading to unauthorized access or data leakage. The reflected XSS can also be used to deliver malware or redirect users to phishing sites, damaging brand reputation and customer trust. Given the plugin's niche, critical infrastructure impact is limited, but the aggregated effect on many SMEs could be significant, especially in countries with high WordPress adoption. Additionally, GDPR implications arise if personal data is compromised through such attacks, potentially leading to regulatory fines. The requirement for user interaction means social engineering campaigns targeting customers or employees are likely vectors. The vulnerability could also be leveraged as a foothold for further attacks within an organization's network if combined with other weaknesses.

1. Immediate mitigation involves disabling or removing the vulnerable Electrician - Electrical Service plugin until a patch is released. 2. Monitor official vergatheme channels and WordPress plugin repositories for updates or patches addressing CVE-2025-31055 and apply them promptly. 3. Implement Web Application Firewall (WAF) rules to detect and block common reflected XSS payload patterns targeting the plugin's endpoints. 4. Educate users and employees about phishing and social engineering risks to reduce the likelihood of clicking malicious links. 5. Employ Content Security Policy (CSP) headers to restrict execution of unauthorized scripts in browsers, mitigating impact of XSS. 6. Conduct regular security audits and vulnerability scans on WordPress installations to identify outdated or vulnerable plugins. 7. Limit plugin usage to trusted sources and consider alternative plugins with better security track records. 8. Harden WordPress installations by enforcing least privilege principles for user roles and disabling unnecessary features that could be exploited.
