What is CVE-2026-42860?

The Open edX Enterprise Service app contains a vulnerability that allows an authenticated user with an Enterprise Admin role to set an arbitrary URL in the SAMLProviderConfig.metadata_source field. This is possible through the SAMLProviderConfigViewSet PATCH endpoint. The subsequent call to the sync_provider_data endpoint triggers a server-side HTTP request without sufficient safeguards, such as scheme enforcement or timeout settings. As a result, this could potentially lead to security risks, including unauthorized data access and exploitation. Users are advised to upgrade to version 7.0.5, where this issue has been addressed.

Affected Version(s)

edx-enterprise >= 7.0.2, < 7.0.5
