CVE-2026-1728
CriticalCVSS 9.8Exploitation Probability (EPSS)
Low risk22th percentile - higher than 22% of all known CVEs
Summary
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.
Risk Assessment
Exploitation can lead to full administrative account takeover. The attack requires the attacker to already possess a low-privileged user account and obtain a valid token for it.
Recommendation
Restrict token privileges for low-privileged users to prevent access to Admin APIs. Implement appropriate access controls.
Other vulnerabilities in WSO2 products
See all- 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-2025-0663Medium
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.
- 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)
Tokens issued to a low-privileged user are not sufficiently restricted, allowing them to be used to access product-level Admin REST APIs. Exploitation of this vulnerability allows a low-privileged user to invoke the Admin REST APIs of WSO2 products, potentially leading to full administrative account takeover. This requires the attacker to already possess a low-privileged user account and be able to obtain a valid token for it.
