CVE-2025-67078 is a reflected cross-site scripting (XSS) vulnerability identified in the Omnispace Agora Project prior to version 25.10. The vulnerability arises from improper sanitization of the 'notify' parameter within the file controller component, which is responsible for displaying error messages. An attacker can craft a malicious URL containing a specially crafted payload in the 'notify' parameter, which when visited by a user, causes the victim's browser to execute arbitrary JavaScript code. This can lead to theft of session tokens, redirection to malicious sites, or execution of unauthorized actions within the context of the victim's session. The vulnerability does not require any authentication or privileges, but does require user interaction (clicking or visiting a crafted link). The CVSS 3.1 base score is 6.1, indicating medium severity, with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N. This means the attack is network-based, has low complexity, requires no privileges, but does require user interaction. The scope is changed, indicating that the vulnerability affects resources beyond the initially vulnerable component. Confidentiality and integrity impacts are low, while availability is unaffected. No patches or exploits are currently reported, but the vulnerability is publicly disclosed and should be addressed promptly. The CWE identifier is CWE-79, which corresponds to improper neutralization of input during web page generation leading to XSS.

The primary impact of CVE-2025-67078 is the potential compromise of user confidentiality and integrity through execution of arbitrary scripts in the victim's browser. This can enable attackers to steal sensitive information such as session cookies, perform actions on behalf of the user, or deliver further malware. While availability is not impacted, the breach of confidentiality and integrity can lead to broader security incidents including account takeover or data leakage. Organizations using the vulnerable Omnispace Agora versions risk exposure of their users to phishing, session hijacking, and other web-based attacks. The requirement for user interaction limits automated exploitation but does not eliminate risk, especially in environments where users may be targeted via phishing or malicious links. The vulnerability could be leveraged in targeted attacks against organizations relying on this software for error handling and user notifications, potentially affecting customer trust and regulatory compliance.

Immediate mitigation involves implementing strict input validation and output encoding on the 'notify' parameter to neutralize malicious scripts. Web application firewalls (WAFs) can be configured to detect and block suspicious payloads targeting this parameter. Organizations should monitor logs for unusual requests containing script tags or encoded payloads in the 'notify' parameter. User education to avoid clicking untrusted links can reduce risk. Once available, upgrading to Omnispace Agora version 25.10 or later that includes the official patch is critical. Developers should review error handling components to ensure all user-controllable inputs are properly sanitized. Employing Content Security Policy (CSP) headers can further mitigate the impact of XSS by restricting script execution sources. Regular security testing, including automated scanning and manual code review focused on input handling, will help prevent similar vulnerabilities.
