CVE-2025-47507 is a security vulnerability classified as CWE-79, which corresponds to Improper Neutralization of Input During Web Page Generation, commonly known as Cross-site Scripting (XSS). Specifically, this vulnerability affects the Ajay Better Search product up to version 4.1.0. The nature of the vulnerability is DOM-based XSS, meaning that the malicious script is executed as a result of modifying the Document Object Model (DOM) environment in the victim's browser, rather than being directly injected into the server response. This type of XSS occurs when client-side scripts write data provided by the user to the DOM without proper sanitization or validation, allowing attackers to execute arbitrary JavaScript in the context of the victim's browser session. The CVSS 3.1 base score is 6.5, indicating a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) reveals that the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), but requires the attacker to have some privileges (PR:L) and the victim to interact with the malicious content (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the security scope of the vulnerable component. The impact on confidentiality, integrity, and availability is low to medium (C:L/I:L/A:L), reflecting that the attacker can potentially steal some data, modify content, or cause limited disruption. No known exploits are currently in the wild, and no patches have been linked yet. The vulnerability was published on May 7, 2025, and is tracked by Patchstack and CISA enrichment. The affected product, Ajay Better Search, is a search enhancement tool, likely integrated into websites or web applications to improve search functionality.

For European organizations using Ajay Better Search, this vulnerability poses a risk of client-side attacks that can lead to session hijacking, theft of sensitive information such as cookies or tokens, and manipulation of web page content. Since the vulnerability is DOM-based, it primarily affects end users interacting with the vulnerable web application, potentially undermining user trust and exposing personal data. The changed scope indicates that the impact could extend beyond the immediate application, possibly affecting other integrated systems or services. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and e-commerce, may face compliance issues and reputational damage if exploited. Although exploitation requires some privileges and user interaction, the low attack complexity means that attackers with limited resources could craft convincing phishing or social engineering campaigns to trigger the vulnerability. The absence of known exploits in the wild currently reduces immediate risk, but the medium severity and potential for data leakage warrant proactive measures.

European organizations should prioritize the following specific mitigations: 1) Conduct a thorough audit of all user input handling in Ajay Better Search, focusing on client-side scripts that manipulate the DOM. 2) Implement strict input validation and output encoding, especially for dynamic content insertion points, using secure JavaScript libraries or frameworks that automatically handle sanitization. 3) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. 4) Monitor and restrict user privileges within the application to minimize the risk posed by low-privilege attackers. 5) Educate users about the risks of interacting with suspicious links or content to reduce the likelihood of successful social engineering. 6) Stay updated with vendor advisories and apply patches promptly once available. 7) Use web application firewalls (WAFs) configured to detect and block XSS attack patterns targeting the affected product. 8) Perform regular security testing, including automated and manual penetration testing focused on DOM-based XSS vectors.
