A cross-tenant authentication vulnerability exists in multiple WSO2 products due to improper cryptographic design in Adaptive Authentication. A single cryptographic key is used across all tenants to sign authentication cookies, allowing a privileged user in one tenant to forge authentication cookies for users in other tenants. Because the Auto-Login feature is enabled by default, this flaw may allow an attacker to gain unauthorized access and potentially take over accounts in other tenants. Successful exploitation requires access to Adaptive Authentication functionality, which is typically restricted to high-privileged users. The vulnerability is only exploitable when Auto-Login is enabled, reducing its practical impact in deployments where the feature is disabled.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.8, indicating it requires adjacent network access with relatively low complexity without requiring user interaction . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 3 products from wso2, from wso2, from wso2 organizations running these solutions should prioritize assessment and patching.
Reported in 2025, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For wso2's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
