UTMStack versions prior to 11.2.16 have a server-side request forgery (SSRF) vulnerability in the IdentityProviderService.validateMetadataUrl() function. This flaw allows authenticated attackers to supply a malicious metadata URL to the identity-providers endpoint, causing the server to send requests to arbitrary internal or cloud metadata hosts. The vulnerability affects the POST/PUT /api/identity-providers endpoint, which does not validate the target host, IP address, or URL scheme. Exploitation can enable internal network port scanning and access to cloud instance-metadata services.
AI Analysis
Technical Summary
CVE-2026-82040 is a server-side request forgery vulnerability in UTMStack prior to version 11.2.16. The flaw exists in the IdentityProviderService.validateMetadataUrl() method, which fails to validate the target host, IP address, or URL scheme when processing metadata URLs supplied to the POST/PUT /api/identity-providers endpoint. Authenticated attackers can leverage this to force the server to send requests to arbitrary internal or cloud metadata services, enabling internal network reconnaissance and potential exposure of sensitive cloud instance metadata.
Potential Impact
The vulnerability allows authenticated attackers to perform SSRF attacks that can lead to internal network port scanning and unauthorized access to cloud instance metadata services. This may expose sensitive information about the internal network or cloud environment. The CVSS score of 5.0 (medium severity) reflects the limited impact on confidentiality with no direct integrity or availability impact reported.
Mitigation Recommendations
A fix is available in UTMStack version 11.2.16. Users should upgrade to version 11.2.16 or later to remediate this vulnerability. No additional mitigation guidance is provided in the vendor advisory; therefore, upgrading is the recommended action.
