CVE-2026-25352 is a security vulnerability classified as Reflected Cross-site Scripting (XSS) affecting skygroup's MyDecor product versions before 1.5.9. The root cause is improper neutralization of user-supplied input during the dynamic generation of web pages, which allows attackers to inject malicious JavaScript code that is reflected back to users without adequate sanitization or encoding. This vulnerability can be exploited by crafting malicious URLs or input parameters that, when visited or submitted by a victim, execute attacker-controlled scripts in the victim's browser context. Such scripts can steal session cookies, perform actions on behalf of the user, or redirect users to phishing or malware sites. The vulnerability does not require authentication, increasing its risk profile, and can be triggered via social engineering techniques such as phishing emails containing malicious links. Although no public exploits have been reported yet, the vulnerability is publicly disclosed and documented in the CVE database, making it likely to be targeted by attackers in the near future. The absence of a CVSS score indicates that detailed impact metrics are not yet assigned, but the nature of reflected XSS vulnerabilities typically implies significant risk to confidentiality and integrity of user sessions. The affected product, MyDecor, is a web-based application likely used in interior design or related industries, which may have customer-facing portals or administrative interfaces vulnerable to this attack. The vulnerability affects all versions prior to 1.5.9, and no patch links are currently provided, suggesting that users should monitor vendor communications for updates. Interim mitigations include implementing strict input validation, output encoding, and deploying Web Application Firewalls (WAFs) with XSS detection rules.

The primary impact of CVE-2026-25352 is the compromise of user confidentiality and integrity through the execution of arbitrary scripts in the context of a victim's browser. Attackers can hijack user sessions, steal authentication tokens, or manipulate web content to perform unauthorized actions. This can lead to account takeover, data leakage, and reputational damage for organizations. Additionally, attackers may use the vulnerability to redirect users to malicious websites, facilitating further malware infections or phishing attacks. Since the vulnerability is reflected XSS, it requires user interaction, typically clicking on a malicious link, which can be distributed via email or social media. The scope of affected systems includes all installations of skygroup MyDecor versions prior to 1.5.9, especially those exposed to the internet. Organizations relying on MyDecor for customer engagement or internal operations may face service disruption or data breaches if exploited. The absence of known exploits in the wild currently limits immediate impact, but the public disclosure increases the risk of future attacks. Overall, the vulnerability poses a high risk to organizations that do not promptly address it.

Organizations should immediately inventory their deployments of skygroup MyDecor and identify any instances running versions prior to 1.5.9. They should monitor skygroup's official channels for patches or updates addressing this vulnerability and apply them as soon as they become available. In the interim, implement rigorous input validation on all user-supplied data to ensure that scripts or HTML tags are not accepted or are properly escaped. Employ output encoding techniques such as HTML entity encoding to neutralize any reflected input before rendering it in the browser. Deploy Web Application Firewalls (WAFs) with rules specifically designed to detect and block reflected XSS attack patterns targeting MyDecor endpoints. Educate users and staff about the risks of clicking on suspicious links, especially those purporting to come from MyDecor-related communications. Conduct regular security assessments and penetration testing focused on XSS vulnerabilities. Finally, consider implementing Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the browser context, reducing the impact of any successful injection.
