CVE-2025-49961 is a Missing Authorization vulnerability identified in Breeze Team's Breeze Checkout product, affecting all versions up to and including 1.4.0. The vulnerability arises from incorrectly configured access control security levels, allowing attackers with some level of privileges (PR:L) to bypass authorization checks. This means that an attacker who has authenticated access but limited privileges could perform actions or access resources beyond their intended permissions. The vulnerability is exploitable remotely over the network (AV:N) without requiring user interaction (UI:N), which increases the risk of exploitation in automated or targeted attacks. The impact includes limited confidentiality, integrity, and availability losses, as indicated by the CVSS vector (C:L/I:L/A:L). Although no known exploits are currently reported in the wild, the flaw represents a significant risk for organizations relying on Breeze Checkout for processing payments or managing e-commerce transactions. The lack of patches at the time of publication necessitates immediate attention to access control configurations and monitoring for suspicious activity. The vulnerability was reserved in June 2025 and published in October 2025, indicating recent discovery and disclosure. Breeze Checkout is a payment processing solution, and improper authorization could lead to unauthorized transaction manipulation, data leakage, or service disruption.

For European organizations, this vulnerability poses a risk to the confidentiality, integrity, and availability of payment processing operations. Unauthorized access could allow attackers to view or manipulate transaction data, potentially leading to financial fraud, data breaches involving customer payment information, or disruption of e-commerce services. This could damage customer trust and lead to regulatory non-compliance under GDPR and PCI DSS standards. The medium severity rating reflects that while the impact is limited, the ease of network exploitation without user interaction and the requirement of only low privileges make it a credible threat. Organizations heavily reliant on Breeze Checkout for online payments, especially those processing large volumes of transactions, could face operational and reputational impacts if exploited. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for targeted attacks or future exploit development.

1. Immediately review and audit all access control configurations within Breeze Checkout to ensure that authorization checks are correctly enforced and privilege levels are appropriately assigned. 2. Restrict user privileges to the minimum necessary to perform their roles, implementing the principle of least privilege. 3. Monitor logs and alerts for unusual access patterns or privilege escalations related to Breeze Checkout. 4. Implement network segmentation and firewall rules to limit access to Breeze Checkout administrative interfaces to trusted IP addresses only. 5. Stay informed on vendor communications and apply security patches or updates as soon as they become available. 6. Conduct penetration testing and vulnerability assessments focusing on authorization mechanisms within Breeze Checkout. 7. Educate staff on secure handling of credentials and the risks associated with privilege misuse. 8. Consider deploying Web Application Firewalls (WAF) with custom rules to detect and block suspicious requests targeting authorization bypass attempts.
