CVE-2024-9517: WSO2 refresh token grant account lockout bypass

CVE-2024-9517 · Severity: medium · CVSS 4.9 · Published 2026-11-02

WSO2's identity and access management products issue new access tokens via refresh token grants without re-validating whether user accounts have been locked or blocked. An attacker who obtains a refresh token can bypass account lockout mechanisms to gain ongoing access to a blocked user's account and associated resources, potentially leading to unauthorized data access or fraudulent actions.

Technologies: WSO2 API Manager, WSO2 Identity Server. Vendors: Wso2.

Technical details

The refresh token grant type in WSO2 products fails to re-validate account status (blocked, locked, or disabled) when issuing new access tokens. An attacker in possession of a valid refresh token can obtain new access tokens for accounts that have since been locked or blocked in the user store, circumventing account lockout controls. This is a server-side validation weakness exploitable by any party holding a refresh token from a later-blocked account.
