Open Access Management (OpenAM) is an access management solution. (CVE-2026-46498)
Open Access Management (OpenAM) versions prior to 16.1.1 contain a vulnerability in the OAuthTokenStore and OAuthAdapter components. The OAuthTokenStore reads token identifiers from the shared Core Token Store (CTS) without enforcing an OAuth-only namespace, and OAuthAdapter accepts token data without verifying its integrity or binding to a trusted CTS type. This allows an attacker who can insert controlled JSON into the CTS under a known token identifier to mint OAuth bearer tokens and OpenID Connect ID tokens with arbitrary attributes. The vulnerability does not directly create an OpenAM SSO session or grant console access. The issue is fixed in version 16.1.1.
AI Analysis
Technical Summary
OpenAM prior to version 16.1.1 has a vulnerability where OAuthTokenStore improperly reads caller-supplied token identifiers from the shared Core Token Store without restricting to an OAuth-only namespace. Additionally, OAuthAdapter accepts token data without verifying integrity or binding to a trusted CTS type. An attacker able to place crafted JSON in the CTS under a known token identifier (e.g., via Push Registration and an anonymous SNS callback) can mint OAuth bearer tokens and OpenID Connect ID tokens with attacker-chosen subject, client, realm, and scope. This flaw does not by itself create an SSO session or console access. The vulnerability is resolved in OpenAM 16.1.1.
Potential Impact
An attacker with the ability to place controlled JSON data in the Core Token Store under a known token identifier can forge OAuth bearer tokens and OpenID Connect ID tokens with arbitrary claims. However, this does not directly grant single sign-on sessions or administrative console access. The impact is limited to token minting capabilities without immediate session or console compromise.
Mitigation Recommendations
Upgrade OpenAM to version 16.1.1 or later, where this vulnerability is fixed. No other mitigation is indicated or required according to the available information.
