CVE-2026-46623 Vulnerability Summary

CVE-2026-46623: Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the OAuth2 authentication module updates an existing local account with profile attributes that can include userPassword and inetUserStatus, rewriting the password to the username and reactivating disabled accounts. The missing OAuth.removeRestrictedAccountUpdateAttributes filtering permits these credential and status fields to reach the account update. With account creation enabled, repeated OAuth login causes the default ldapService chain to accept the username as both identifier and password, allowing an unauthenticated attacker to take over the local account without interacting with the identity provider. The rewrite can be denied for usernames shorter than the configured minimum password length. This issue is fixed in version 16.1.1.

Assessing the Risk of CVE-2026-46623

Access Complexity Graph

The exploitability of CVE-2026-46623 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2026-46623

No exploitability data is available for CVE-2026-46623.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2026-46623, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
