Open Access Management (OpenAM) is an access management solution. (CVE-2026-53660)
Open Access Management (OpenAM) prior to version 16.1.1 has a vulnerability where the default configuration sets the iPlanetDirectoryPro SSO cookie without HttpOnly and SameSite protections. This cookie is reused as a CSRF token in OAuth and OpenID Connect consent flows. Combined with same-origin cross-site scripting and user interaction with attacker-controlled links, this can lead to theft of the SSO session and unauthorized consent grants. The issue is fixed in version 16.1.1.
AI Analysis
Technical Summary
OpenAM versions before 16.1.1 initialize the iPlanetDirectoryPro SSO cookie with HttpOnly disabled and no SameSite attribute, allowing the cookie to be read via same-origin cross-site scripting. The OAuth and OpenID Connect consent flows reuse this cookie as a CSRF token. An attacker who can induce a user to follow a malicious link and exploit same-origin XSS can steal the SSO cookie and perform attacker-driven consent grants. This vulnerability is addressed in OpenAM version 16.1.1.
Potential Impact
An attacker can steal the SSO session cookie by exploiting same-origin cross-site scripting combined with user interaction, leading to unauthorized access and consent grants in OAuth and OpenID Connect flows. This compromises user session integrity and authorization controls.
Mitigation Recommendations
Upgrade OpenAM to version 16.1.1 or later, where the vulnerability is fixed by properly configuring the iPlanetDirectoryPro SSO cookie with HttpOnly enabled and appropriate SameSite attributes. No other mitigation is indicated by the vendor advisory.
