Administrator-level code execution via unrestricted policy upload
Published Feb 19, 2026 · Updated Feb 19, 2026
Arbitrary file upload in WSO2 API Manager products allows remote authenticated users with administrator access to execute code. The throttling-policy import REST API accepts an attacker-controlled filename and content without restricting file types or verifying that the canonical destination remains inside the intended import directory. Administrator permission is required; a crafted upload can place executable content at a chosen deployment path and run code in the server context.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=4.5.0 <4.5.0.37
- Affected versionversion=4.6.0 <4.6.0.3
