CVE-2026-105122: Server-Side Request Forgery (SSRF) in OpenIdentityPlatform OpenAM
OpenAM before 16.1.3 contains a server-side request forgery vulnerability that allows attackers able to register or modify OAuth 2.0 clients to make OpenAM fetch internal resources via an unvalidated jwks_uri. Attackers can trigger unauthenticated fetches through client-authentication and ID-token validation to probe internal hosts, metadata endpoints or local files, or exhaust request threads for denial of service.
AI Analysis
Technical Summary
CVE-2026-105122 is an SSRF vulnerability in OpenIdentityPlatform's OpenAM before version 16.1.3. Attackers with the ability to register or modify OAuth 2.0 clients can exploit an unvalidated jwks_uri to make OpenAM perform unauthorized fetches of internal hosts, metadata endpoints, or local files. These fetches occur during client authentication and ID-token validation processes. The vulnerability can be leveraged to probe internal network resources or cause denial of service by exhausting server request threads.
Potential Impact
The vulnerability allows unauthorized internal resource access through SSRF, potentially exposing sensitive internal endpoints or files. Additionally, it can be used to exhaust server resources, leading to denial of service conditions. No authenticated user interaction is required beyond the ability to register or modify OAuth 2.0 clients.
Mitigation Recommendations
A fix is available in OpenAM version 16.1.3. Users should upgrade to version 16.1.3 or later to remediate this vulnerability. No vendor advisory content was provided to indicate alternative mitigations or temporary fixes.
