CVE-2026-1153 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the technical-laohu mpay product, versions 1.2.0 through 1.2.4. CSRF vulnerabilities allow attackers to induce authenticated users to perform unwanted actions on a web application in which they are currently authenticated. In this case, the vulnerability affects an unspecified function within mpay, a payment processing or financial transaction platform. The attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), but requires user interaction (UI:P). The vulnerability does not compromise confidentiality but impacts integrity and availability to a limited extent. The vulnerability is exploitable remotely by tricking users into submitting crafted requests, potentially causing unauthorized transactions or changes in the mpay system. Although no known exploits are currently active in the wild, a public exploit is available, increasing the risk of exploitation. The lack of patch links suggests that a fix may not yet be publicly released, so organizations must apply compensating controls. The CVSS 4.0 vector indicates no scope change and no authentication required, emphasizing the importance of securing user sessions and request validation mechanisms. The vulnerability highlights the need for robust anti-CSRF protections such as synchronizer tokens or SameSite cookie attributes.

For European organizations, especially those in financial services or e-commerce sectors using technical-laohu mpay, this vulnerability could lead to unauthorized financial transactions, manipulation of payment data, or disruption of payment services. The integrity of transaction data could be compromised, leading to financial loss, reputational damage, and regulatory non-compliance under GDPR and PSD2 frameworks. Since exploitation requires user interaction but no authentication, phishing or social engineering campaigns could be used to trigger malicious requests. The impact on availability is limited but possible if attackers cause repeated unauthorized actions that disrupt service. Organizations relying on mpay for critical payment processing must consider the risk of fraud and operational disruption. The medium severity rating suggests that while the threat is not critical, it is significant enough to warrant prompt mitigation to avoid exploitation and potential cascading effects in payment ecosystems.

1. Implement anti-CSRF tokens in all state-changing requests within the mpay application to ensure that requests originate from legitimate users. 2. Enforce strict validation of the Origin and Referer HTTP headers to block cross-origin requests that could be malicious. 3. Configure cookies with the SameSite attribute set to 'Strict' or 'Lax' to limit cookie transmission in cross-site contexts. 4. Educate users about phishing and social engineering risks to reduce the likelihood of user interaction with malicious links. 5. Monitor application logs for unusual or unauthorized transaction patterns that may indicate exploitation attempts. 6. Apply network-level protections such as Web Application Firewalls (WAFs) with rules to detect and block CSRF attack patterns. 7. Stay alert for official patches or updates from technical-laohu and apply them promptly once released. 8. Conduct regular security assessments and penetration testing focused on CSRF and related web vulnerabilities. 9. Limit the exposure of the mpay interface to trusted networks or VPNs where feasible to reduce attack surface. 10. Implement multi-factor authentication for sensitive operations to add an additional layer of security beyond session cookies.
