No CVSS score has been assigned to CVE-2026-46619 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2026-46619?

CVE-2026-46619 affects the following packages: org.openidentityplatform.openam:openam-auth-msisdn (Maven). Ecosystems affected: Maven.

How do I fix CVE-2026-46619?

Update org.openidentityplatform.openam:openam-auth-msisdn to 16.1.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-46619 is resolved across your whole dependency graph.

How do I detect CVE-2026-46619 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.openidentityplatform.openam:openam-auth-msisdn, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2026-46619 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Is CVE-2026-46619 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-46619 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-46619?

CVE-2026-46619 has an EPSS (Exploit Prediction Scoring System) score of 1.0%, placing it in the 62th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2026-46619?

CVE-2026-46619 is classified as CWE-90 (CWE-90). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
A successful exploit gives an attacker total control of the affected component, not partial access.
CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

Description

Summary

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.

Patch

This has been patched in OpenAM Community Edition version 16.1.1. Users are encouraged to update to the latest release.
