CVE-2026-105120: Exposure of Sensitive Information to an Unauthorized Actor in OpenIdentityPlatform OpenAM
OpenAM before 16.1.3 contains an authorization bypass vulnerability in the sessions REST endpoint query operation that allows realm administrators to list sessions of every realm. Attackers holding delegated RealmAdmin privileges can supply a _queryFilter naming another realm to disclose usernames, universal IDs, and session handles across tenant boundaries.
AI Analysis
Technical Summary
CVE-2026-105120 describes an authorization bypass vulnerability in OpenIdentityPlatform's OpenAM product prior to version 16.1.3. The issue exists in the sessions REST endpoint query operation, where realm administrators with delegated RealmAdmin privileges can manipulate the _queryFilter parameter to enumerate sessions belonging to other realms. This leads to unauthorized disclosure of sensitive session-related information across tenant boundaries.
Potential Impact
An attacker with delegated RealmAdmin privileges can bypass authorization controls to access sensitive session information from other realms. This includes usernames, universal IDs, and session handles, potentially compromising tenant isolation and exposing sensitive user session data.
Mitigation Recommendations
Upgrade OpenAM to version 16.1.3 or later where this vulnerability is fixed. Since the vulnerability affects versions before 16.1.3, applying the official patch or upgrading to the fixed version is the recommended remediation.
