CVE-2025-50574 identifies a cross-site scripting (XSS) vulnerability in the blog-details.php file of Hiruna Gallage's Glamour Salon Management System version 1. The vulnerability arises because the application fails to properly sanitize or encode user-supplied input in the blog comment section parameter, allowing attackers to inject malicious JavaScript or HTML code. When a victim views the affected blog page, the injected script executes in their browser context, enabling attackers to steal session cookies, perform actions on behalf of the user, or redirect users to malicious sites. This type of vulnerability is common in web applications that accept user-generated content without adequate input validation or output encoding. Although no CVSS score has been assigned and no public exploits are known, the flaw is publicly disclosed and thus could be targeted by attackers. The Glamour Salon Management System is likely used by small to medium-sized salon businesses to manage appointments, services, and customer interactions, including blog features for marketing. The vulnerability impacts confidentiality (through session theft), integrity (through content manipulation), and potentially availability (via persistent XSS leading to denial of service). The lack of authentication requirement and the remote exploitation vector increase the risk. The absence of a patch link indicates that a fix may not yet be available, emphasizing the need for immediate mitigation steps by users of this software.

For European organizations, especially small and medium-sized enterprises in the beauty and salon industry using Glamour Salon Management System v1, this vulnerability could lead to significant reputational damage and loss of customer trust if attackers exploit the XSS flaw to hijack user sessions or deface public-facing content. Confidential customer data, such as session tokens or personal information entered in the blog comment section, could be compromised. The integrity of the website content could be undermined, potentially leading to misinformation or fraudulent promotions. Persistent XSS attacks could also degrade service availability by causing browsers to crash or by triggering automated defenses. Given the public-facing nature of the blog comment feature, the attack surface is broad, and exploitation does not require authentication, increasing the likelihood of attacks. Additionally, regulatory compliance risks exist under GDPR if personal data is exposed or mishandled due to this vulnerability. The impact is thus both technical and business-oriented, affecting operational continuity and legal compliance.

To mitigate CVE-2025-50574, organizations should immediately implement strict input validation and output encoding on the blog comment section parameter to neutralize malicious scripts. Employ context-aware encoding (e.g., HTML entity encoding) before rendering user input in the browser. If possible, disable or restrict the blog comment feature until a vendor patch is available. Deploy a Web Application Firewall (WAF) with rules to detect and block common XSS attack patterns targeting the affected parameter. Conduct regular security testing, including automated scanning and manual code reviews, focusing on user input handling. Educate staff and users about the risks of clicking suspicious links or interacting with untrusted content. Monitor web server logs and application behavior for unusual activity indicative of exploitation attempts. Engage with the software vendor or community to obtain or develop patches and updates. Finally, consider implementing Content Security Policy (CSP) headers to reduce the impact of any successful script injection.
