CVE-2025-28882 identifies a reflected cross-site scripting (XSS) vulnerability in Omnify, Inc.'s Omnify product, specifically within the omnify-widget component. This vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing malicious scripts to be injected and executed in the context of a victim's browser session. Reflected XSS typically occurs when input from HTTP requests is immediately included in the response without adequate sanitization or encoding. The affected versions include all releases up to and including 2.0.3. Although no exploits have been reported in the wild, the vulnerability presents a significant risk because attackers can craft URLs or input vectors that, when visited or interacted with by users, execute arbitrary JavaScript code. This can lead to session hijacking, credential theft, defacement, or redirection to malicious sites. The vulnerability does not require authentication but does require user interaction, such as clicking a malicious link. The lack of a CVSS score indicates that the vulnerability is newly published, but based on the nature of reflected XSS and the affected product's usage in web-based event and resource management, the threat is substantial. No official patches or mitigation links were provided at the time of publication, emphasizing the need for immediate attention by affected organizations.

The primary impact of CVE-2025-28882 is on the confidentiality and integrity of user data and sessions within applications using Omnify. Successful exploitation can allow attackers to steal session cookies, credentials, or other sensitive information, potentially leading to unauthorized access to user accounts or administrative functions. It can also enable attackers to perform actions on behalf of users, such as modifying data or initiating transactions. The reflected XSS nature means that attacks require user interaction, which may limit mass exploitation but still poses a significant risk, especially in targeted phishing campaigns. Organizations relying on Omnify for event management, resource scheduling, or customer engagement may face reputational damage, regulatory penalties, and operational disruption if exploited. The vulnerability could also be leveraged as a stepping stone for more complex attacks, such as delivering malware or conducting social engineering. Given the web-facing nature of the affected component, the attack surface is broad, potentially impacting a wide range of industries and sectors globally.

Organizations should immediately assess their use of Omnify and identify if they are running versions up to 2.0.3. In the absence of an official patch, mitigation should focus on implementing robust input validation and output encoding on all user-supplied data within the omnify-widget component. Employing a web application firewall (WAF) with rules to detect and block common XSS attack patterns can provide temporary protection. Security teams should educate users about the risks of clicking on suspicious links and implement Content Security Policy (CSP) headers to restrict script execution sources. Monitoring web server logs for unusual request patterns or error messages related to input handling can help detect attempted exploitation. Once a patch becomes available, organizations must prioritize timely deployment. Additionally, conducting regular security assessments and penetration testing focused on XSS vulnerabilities can help identify and remediate similar issues proactively.
