CVE-2023-6837
Incorrect Authorization in Multiple WSO2 Products via Federated Authentication with JIT Provisioning Leading to User Impersonation
En bref Sévérité HIGH 8.5 EPSS EPSS 0.46 % · centile 40 (2026-10-27) État PUBLISHED Publiée 2023-12-15 Mise à jour 2025-09-25 Attribuée par WSO2 Statut NVD Modified Description Multiple WSO2 products have been identified as vulnerable to perform user impersonatoin using JIT provisioning. In order for this vulnerability to have any impact on your deployment, following conditions must be met:
* An IDP configured for federated authentication and JIT provisioning enabled with the "Prompt for username, password and consent" option.
* A service provider that uses the above IDP for federated authentication and has the "Assert identity using mapped local subject identifier" flag enabled.
Attacker should have:
* A fresh valid user account in the federated IDP that has not been used earlier.
* Knowledge of the username of a valid user in the local IDP.
When all preconditions are met, a malicious actor could use JIT provisioning flow to perform user impersonation.
