A weakness has been identified in technical-laohu mpay up to version 1.2.4. The affected element is an unknown function of the component User Center. This manipulation of the argument Nickname causes cross site scripting. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks.
The CVSS score for this vulnerability is 1.9, classified as low severity. This indicates that while the risk is not critical, it still presents a potential threat that organizations need to address. The ability for an attacker to exploit this vulnerability remotely adds to the urgency for remediation.
Risk to organizations includes unauthorized access to sensitive data and potential manipulation of the application environment. Although the exploit is categorized with low impact, organizations should be mindful of the potential for cross site scripting attacks that could lead to compromised user sessions.
Organizations should prioritize patching immediately, especially those using the affected version of mpay. The availability of public exploits means that the window for potential attacks is open, and proactive measures are essential.
Vulnerability Details
The CVE-2026-1151 vulnerability allows for cross site scripting (XSS) due to an issue with the Nickname argument within the User Center component. The weakness is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation) and CWE-94 (Improper Control of Generation of Code).
The CVSS 4.0 vector string for this vulnerability is CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:N/VI:L/VA:N. This indicates a low attack complexity and a high privilege requirement, meaning that a user with elevated privileges is necessary to exploit this vulnerability.
The affected product is technical-laohu's mpay, with all versions up to and including 1.2.4 being vulnerable. It was published on January 19, 2026, and the last modification was made on April 29, 2026.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input for the Nickname argument. Attackers may leverage this oversight to inject malicious scripts into the application, which can then be executed in the context of users who interact with the affected application.
The attack vector is through the network, allowing for remote exploitation. The complexity is rated as low, requiring minimal effort from the attacker to initiate the exploit. Privileges required are high, meaning that an attacker would need to trick an authorized user into interacting with the malicious code.
User interaction is necessary, as the attack requires a user to click on a link or interact with a malicious payload. The integrity impact is low, indicating that while the confidentiality remains intact, the attacker can alter data in a non-destructive manner.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2026-1151 is notable, especially for organizations relying heavily on the mpay component for user management. Given that this vulnerability can be exploited remotely with relatively low complexity, the potential for a security breach is a valid concern.
The blast radius for this vulnerability could be significant, particularly in environments where mpay is integrated into other systems or applications. An exploit could lead to unauthorized actions being performed under the guise of legitimate users, potentially resulting in data breaches or loss of integrity.
Organizations should assess their patch management processes and prioritize this vulnerability based on its CVSS score of 1.9. Despite being classified as low, the presence of publicly available exploits increases the urgency for remediation.

Affected Versions
The affected versions of technical-laohu mpay are all versions prior to vendor patch 1.2.4.
Mitigation & Remediation
Organizations should update to the latest version of technical-laohu mpay to mitigate this vulnerability. If a patch is unavailable, consider implementing input validation and sanitization measures to prevent XSS attacks.
Further, configuring application firewalls to filter out malicious scripts can provide additional protection. It is also advisable to monitor logs for any unusual activity that may suggest attempted exploitation of this vulnerability.
Continuous security testing can help identify if any vulnerabilities persist after applying patches.
Detection Guidance
To detect potential exploitation of CVE-2026-1151, organizations should look for log indicators of unusual user behavior, especially actions involving the User Center component. Monitoring for behavioral anomalies that deviate from normal usage patterns can also be effective.
Additionally, implementing network signatures to identify potential XSS attacks and monitoring system changes that coincide with user interactions can provide further insights into exploitation attempts.
