Short explanation
In WSO2 products, JWT Bearer and SAML2 Bearer grant flows do not verify whether the Identity Provider (IDP) is disabled. This validation gap lets attackers request tokens for a disabled IDP and use those tokens to access protected resources. The vulnerability scores 4.8 (MEDIUM) on CVSS and no official patch has been confirmed yet.
Unauthorized access tokens can enable attackers to reach protected services without permission.
What should be done?
- Review the WSO2 security advisory
- Patch status is UNKNOWN; monitor vendor advisory for updates
- Consider temporarily disabling JWT/SAML2 Bearer grant types
- Monitor token usage for anomalous activity
The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.
Chain of evidence and sources
Bu açık, devre dışı bırakılmış bir IDP için bile erişim tokenı oluşturulmasına izin verir (S0, S1).
Resmi kaynaklarda yama durumu doğrulanamadı; yama durumu UNKNOWN olarak rapor edilmiştir (S0).
CISA KEV listesinde yer almıyor; aktif istismar rapor edilmemiştir (S0).
Show the technical text from the sources
When utilizing JWT Bearer or SAML2 Bearer grant types, the system fails to validate the status of the Identity Provider (IDP) before issuing access tokens. This oversight permits tokens to be generated even when the associated IDP has been disabled. A malicious actor could leverage this vulnerability to obtain access tokens by targeting a disabled IDP. This could enable them to bypass intended security controls and potentially access protected resources that should be inaccessible due to the IDP's disabled state.
