Summary
OpenAM Authentication Bypass via MSISDN LDAP Injection
Description
An LDAP Injection (CWE-90) vulnerability in the MSISDN authentication module allows an unauthenticated, remote attacker to obtain an arbitrary OpenAM session without a password in the default trusted gateway configuration. This impacts OpenAM Community Edition through version 16.0.6. This issue was patched in version 16.1.1.
Impact
OpenAM deployments through version 16.0.6 that have MSISDN enabled are potentially affected. This enables a pre-authentication login bypass for any realm where an MSISDN module instance is enabled in an authentication chain and reachable through the trusted-gateway list, which allows all traffic by default. The request-supplied MSISDN value was concatenated directly into an LDAP search filter. The resulting OpenAM session is a normal authenticated session for the matched user.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2026-46619? CVE-2026-46619 is a high-severity security vulnerability in org.openidentityplatform.openam:openam-auth-msisdn (maven), affecting versions < 16.1.1. It is fixed in 16.1.1.
- Which versions of org.openidentityplatform.openam:openam-auth-msisdn are affected by CVE-2026-46619? org.openidentityplatform.openam:openam-auth-msisdn (maven) versions < 16.1.1 is affected.
- Is there a fix for CVE-2026-46619? Yes. CVE-2026-46619 is fixed in 16.1.1. Upgrade to this version or later.
- Is CVE-2026-46619 exploitable, and should I be worried? Whether CVE-2026-46619 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-46619 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2026-46619? Upgrade
org.openidentityplatform.openam:openam-auth-msisdnto 16.1.1 or later.
