CVE-2025-52746 is a reflected Cross-site Scripting (XSS) vulnerability identified in the ayecode Restaurante product, affecting versions up to and including 3.0.7. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows attackers to inject malicious JavaScript code that is reflected back to the victim's browser. This type of XSS is triggered when a user interacts with a crafted URL or input that the application fails to sanitize properly. The vulnerability does not require any privileges or authentication to exploit but does require user interaction, such as clicking a malicious link. The CVSS v3.1 base score is 6.1, indicating medium severity, with an attack vector of network (remote), low attack complexity, no privileges required, and user interaction required. The impact primarily affects confidentiality and integrity, as attackers can steal session cookies, perform actions on behalf of the user, or manipulate the content displayed to users. Availability is not impacted. No public exploits have been reported yet, but the vulnerability is published and should be addressed promptly. The lack of patches linked in the provided data suggests that organizations should monitor vendor advisories for updates or apply mitigations proactively. Given that ayecode Restaurante is used in restaurant management, the threat surface includes web-facing interfaces accessible by customers and staff, increasing the risk of exploitation in environments with public or semi-public access.

For European organizations, particularly those in the hospitality and restaurant sectors using ayecode Restaurante, this vulnerability poses a risk to customer and employee data confidentiality and the integrity of web interactions. Attackers exploiting this XSS flaw could hijack user sessions, steal sensitive information such as authentication tokens, or manipulate web content to conduct phishing or fraud. This could lead to reputational damage, regulatory non-compliance (e.g., GDPR violations due to data leakage), and financial losses. Since the vulnerability requires user interaction, social engineering campaigns targeting European customers or staff could be effective. The impact is heightened in countries with large hospitality industries and widespread use of this software. Additionally, compromised systems could be leveraged as footholds for further attacks within organizational networks. Although availability is not directly affected, the indirect consequences of data breaches and loss of trust can disrupt business operations.

Organizations should implement multiple layers of defense to mitigate this vulnerability beyond generic advice. First, apply any available patches or updates from ayecode promptly once released. In the absence of patches, implement strict input validation on all user-supplied data, ensuring that special characters are properly escaped or sanitized before rendering in web pages. Employ context-aware output encoding to prevent script injection. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of successful XSS attacks. Conduct regular security testing, including automated scanning and manual code reviews, to identify similar issues. Educate staff and users about the risks of clicking unknown links and recognizing phishing attempts. Monitor web server logs and network traffic for suspicious activities indicative of exploitation attempts. Consider using Web Application Firewalls (WAFs) with rules tailored to detect and block reflected XSS payloads targeting the Restaurante application. Finally, maintain an incident response plan to quickly address any detected exploitation.
