Low risk14th percentile - higher than 14% of all known CVEs
Summary
A cross-tenant authentication vulnerability exists in multiple WSO2 products due to improper cryptographic design in Adaptive Authentication. A single cryptographic key used across all tenants to sign authentication cookies allows a privileged user in one tenant to forge authentication cookies for users in other tenants.
Risk Assessment
Because Auto-Login is enabled by default, an attacker may gain unauthorized access and take over accounts in other tenants. Exploitation requires access to Adaptive Authentication, typically restricted to high-privileged users.
Recommendation
Apply the vendor patch and disable Auto-Login if not required. Restrict access to Adaptive Authentication to the minimum necessary.
Other vulnerabilities in WSO2 products
See all- CVE-2026-1728Critical
Tokens issued to a low-privileged user are not sufficiently restricted, allowing them to be used to access product-level Admin REST APIs. A low-privileged user can invoke Admin REST APIs of WSO2 products.
- CVE-2025-9804Critical
An improper access control vulnerability exists in multiple WSO2 products due to insufficient permission enforcement in certain internal SOAP Admin Services and System REST APIs. A low-privileged user may exploit this flaw to perform unauthorized operations, including accessing server-level information.
- CVE-2022-29464CriticalActively exploited
Certain WSO2 products allow unrestricted file upload with resultant remote code execution. The attacker must use a /fileupload endpoint with a Content-Disposition directory traversal sequence to reach a directory under the web root, such as ../../../../repository/deployment/server/webapps. Affects WSO2 API Manager 2.2.0-4.0.0, WSO2 Identity Server 5.2.0-5.11.0, WSO2 Identity Server Analytics 5.4.0-5.6.0, WSO2 Identity Server as Key Manager 5.3.0-5.11.0, WSO2 Enterprise Integrator 6.2.0-6.6.0, WSO2 Open Banking AM 1.4.0-2.0.0, and WSO2 Open Banking KM 1.4.0-2.0.0.
- CVE-2025-14260High
WSO2 Products have an improper implementation of access control rules, allowing malicious actors to perform a Server Side Request Forgery (SSRF) attack. Exploitation allows access to both internal and external resources available through the network or filesystem.
- CVE-2025-5717Medium
An authenticated remote code execution (RCE) vulnerability exists in multiple WSO2 products due to improper input validation in the event processor admin service. A user with administrative access to SOAP admin services can deploy a Siddhi execution plan containing malicious Java code, resulting in arbitrary code execution on the server.
Original NVD description (English source)
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.
