CVE-2025-23550 is a reflected Cross-site Scripting (XSS) vulnerability classified under CWE-79, found in the Kemal YAZICI Product Puller software up to version 1.5.1. The vulnerability stems from improper neutralization of user-supplied input during web page generation, allowing malicious scripts to be injected and executed in the context of the victim's browser. This can lead to theft of session cookies, user credentials, or other sensitive information, as well as manipulation of the web application's behavior. The CVSS 3.1 base score is 7.1, indicating a high severity level, with the vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L. This means the attack can be launched remotely over the network with low attack complexity, requires no privileges, but does require user interaction (such as clicking a malicious link). The scope is changed (S:C), indicating that the vulnerability affects resources beyond the vulnerable component, potentially impacting the entire web application. The vulnerability affects confidentiality, integrity, and availability to a limited extent but is significant enough to warrant urgent remediation. No patches or fixes have been published at the time of reporting, and no known exploits are currently in the wild, but the presence of this vulnerability in a web-facing product used for product data aggregation or e-commerce purposes poses a tangible risk. The vulnerability was reserved in January 2025 and published in December 2025, indicating a recent discovery. The lack of patch links suggests that users must implement interim mitigations until an official fix is available.

For European organizations, especially those involved in e-commerce, retail, or product data aggregation using Kemal YAZICI Product Puller, this vulnerability could lead to significant risks. Attackers exploiting the reflected XSS flaw could hijack user sessions, steal sensitive customer data, or perform unauthorized actions on behalf of users, undermining trust and potentially causing regulatory compliance issues under GDPR due to data breaches. The vulnerability's ability to affect confidentiality, integrity, and availability means that business operations could be disrupted, and reputational damage could ensue. Since the Product Puller software is likely used in web-facing environments, the attack surface is broad, and phishing or social engineering could facilitate exploitation. The lack of patches increases exposure time, making proactive mitigation critical. Organizations handling large volumes of customer data or operating in countries with strict data protection laws face heightened legal and financial risks.

European organizations should immediately implement strict input validation and output encoding on all user-supplied data within the Product Puller environment to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. Monitor web application logs for suspicious requests that may indicate attempted exploitation. Educate users about the risks of clicking unknown or suspicious links to reduce successful user interaction exploitation. If possible, isolate the Product Puller application within a segmented network zone to limit lateral movement in case of compromise. Regularly update and patch the software once official fixes are released by the vendor. Consider deploying Web Application Firewalls (WAF) with rules specifically targeting XSS attack patterns to provide an additional layer of defense. Conduct security assessments and penetration tests focusing on XSS vulnerabilities to identify and remediate similar issues proactively.
