CVE-2026-122007
MediumCVSS 6.5Summary
Oqtane Framework before 10.3.0 contains a broken access control vulnerability in SettingController.cs that allows an authenticated site administrator to read and modify settings belonging to other sites within the same tenant database by supplying an arbitrary entityId for Site or Role type settings, since IsAuthorized and FilterPrivate fail to verify the requested site matches the current alias SiteId. Attackers can exploit the /api/setting endpoints to disclose private values such as SMTPPassword, SMTPClientSecret, and ExternalLogin ClientSecret, and to alter another site's OIDC/OAuth2 authentication configuration without requiring host privileges.
Risk Assessment
A site administrator could access sensitive data of other sites and modify their authentication configuration, potentially leading to account takeover or secret disclosure. This requires site administrator privileges.
Recommendation
Update Oqtane Framework to version 10.3.0 or later. Implement proper permission checks for settings based on SiteId.
Other vulnerabilities in Oqtane Framework
See all- CVE-2026-122008Medium
Oqtane Framework before 10.3.0 contains a server-side request forgery vulnerability in the UploadFile endpoint of FileController.cs that allows authenticated registered users to make the server fetch arbitrary URLs by supplying a caller-controlled url parameter to HttpClient.GetStreamAsync without validating the scheme, host, or IP address. Attackers can request internal resources such as cloud instance metadata services or localhost-bound management interfaces, save the fetched response as a file in their own user folder, and retrieve it via the download endpoint to exfiltrate sensitive internal data or enumerate internal network hosts and ports.
- CVE-2026-111616Medium
Oqtane Framework through 10.2.6 contains an authorization bypass vulnerability in SettingController that allows a site administrator to read another co-tenant site's private settings. Attackers with the Administrators role on one site can request another site's entityId through their own alias to retrieve stored SMTPPassword and SMTPClientSecret values.
