CVE-2025-62140 is a Stored Cross-site Scripting (XSS) vulnerability classified under CWE-79, found in the Plainware Locatoraid Store Locator plugin, affecting versions up to 3.9.65. The vulnerability stems from improper neutralization of input during web page generation, which allows malicious scripts to be stored and later executed in the context of users visiting affected web pages. This flaw enables attackers with high privileges (PR:H) to inject malicious payloads that require user interaction (UI:R) to trigger. The CVSS 3.1 base score is 5.9, indicating medium severity, with an attack vector of network (AV:N) and scope change (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. The impact affects confidentiality, integrity, and availability at a low level, as attackers can potentially steal session tokens, manipulate displayed content, or cause denial of service through script execution. No patches or known exploits are currently available, but the vulnerability is publicly disclosed and published. The lack of patches means organizations must rely on mitigation strategies until updates are released. The vulnerability is particularly relevant for websites using the Locatoraid Store Locator plugin to provide store location services, which often involve user input fields that may be exploited for stored XSS attacks. Attackers could leverage this to perform phishing, session hijacking, or defacement attacks against site visitors or administrators.

For European organizations, the impact of CVE-2025-62140 can be significant, especially for those in retail, hospitality, or service industries that use the Locatoraid Store Locator plugin on their websites. Successful exploitation could lead to theft of user credentials, session hijacking, or unauthorized actions performed on behalf of legitimate users, undermining customer trust and potentially causing regulatory compliance issues under GDPR due to data exposure. The vulnerability's ability to affect confidentiality, integrity, and availability, even at low levels, can disrupt business operations and damage brand reputation. Since the attack requires authenticated users with high privileges and user interaction, internal staff or trusted users could be targeted, increasing the risk of insider threats or social engineering attacks. Additionally, the scope change aspect means that the vulnerability could impact other components or data beyond the plugin itself, potentially escalating the damage. The absence of known exploits in the wild currently reduces immediate risk, but the public disclosure increases the likelihood of future exploitation attempts. European organizations must consider these risks in their threat models and incident response plans.

To mitigate CVE-2025-62140 effectively, European organizations should implement the following specific measures: 1) Restrict administrative and high-privilege user access to the minimum necessary, enforcing the principle of least privilege to reduce the risk of malicious input injection. 2) Implement rigorous input validation and sanitization on all user-supplied data fields within the Locatoraid Store Locator plugin, ensuring that potentially dangerous characters are neutralized before storage or rendering. 3) Apply context-aware output encoding (e.g., HTML entity encoding) when displaying user input to prevent script execution. 4) Monitor web application logs and user activity for unusual patterns indicative of XSS attempts or abuse by privileged users. 5) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected web pages. 6) Isolate the plugin environment where possible, limiting its access to sensitive data and other application components to contain potential exploitation impact. 7) Prepare for rapid deployment of patches once released by Plainware by maintaining an up-to-date inventory of affected systems. 8) Conduct security awareness training for administrators and users with high privileges to recognize and avoid social engineering attempts that could facilitate exploitation. 9) Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block XSS payloads targeting the plugin. These targeted actions go beyond generic advice and address the specific nature of the vulnerability and its exploitation requirements.
