CVE-2025-62140 identifies a Stored Cross-Site Scripting (XSS) vulnerability in the Plainware Locatoraid Store Locator plugin, versions up to 3.9.65. The root cause is improper neutralization of user-supplied input during the generation of web pages, categorized under CWE-79. This vulnerability allows an attacker with high privileges (PR:H) and requiring user interaction (UI:R) to inject malicious scripts that are persistently stored and executed in the context of other users visiting the affected web pages. The CVSS vector indicates network attack vector (AV:N), low attack complexity (AC:L), and a scope change (S:C), meaning the vulnerability can affect resources beyond the initially compromised component. The impact includes limited confidentiality, integrity, and availability losses, such as theft of session tokens, unauthorized actions, or denial of service. No patches are currently linked, and no known exploits have been observed in the wild, suggesting the vulnerability is either newly disclosed or not yet weaponized. The vulnerability is particularly relevant for organizations using Locatoraid Store Locator on their websites, especially those with administrative users who can be targeted to inject malicious payloads. The persistent nature of the XSS increases the risk to all users accessing the affected pages. The vulnerability requires authentication and user interaction, limiting the attack surface but still posing a significant risk if exploited.

For European organizations, this vulnerability can lead to unauthorized access to user sessions, defacement of websites, or injection of malicious content that could facilitate phishing or malware distribution. Retailers and businesses using Locatoraid Store Locator to provide store information on their websites may see reputational damage and customer trust erosion if exploited. The partial compromise of confidentiality and integrity can expose sensitive customer data or internal administrative functions. Availability impacts could arise from denial-of-service conditions triggered by malicious scripts. Given the vulnerability requires authenticated access and user interaction, insider threats or targeted phishing campaigns could increase exploitation likelihood. The absence of known exploits currently reduces immediate risk but does not eliminate the potential for future attacks. Organizations in sectors with high customer interaction, such as retail, hospitality, and services, are particularly vulnerable. Compliance with GDPR mandates protecting customer data, and exploitation could lead to regulatory penalties and legal consequences.

Organizations should monitor Plainware’s official channels for patches addressing CVE-2025-62140 and apply them promptly once available. In the interim, implement strict input validation and output encoding on all user-supplied data within the Locatoraid Store Locator plugin to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Limit administrative access to the plugin to trusted personnel and enforce multi-factor authentication to reduce the risk of credential compromise. Conduct regular security audits and penetration testing focusing on web application vulnerabilities, including XSS. Educate users and administrators about phishing risks and the importance of cautious interaction with suspicious links or inputs. Consider deploying Web Application Firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting the plugin. Maintain comprehensive logging and monitoring to detect anomalous activities indicative of exploitation attempts.
