CVE-2026-45794: OpenIdentityPlatform OpenAM unsafe Java deserialization in SNS callback

CVE-2026-45794 · Severity: high · CVSS 4 · Published 2026-09-15

OpenAM is an open-source access management platform used to secure web applications and services. A vulnerability in its push notification system allows an attacker to trick the server into running unauthorized code or performing unintended actions like file modification. This could lead to a complete system takeover or service disruption, though it requires the attacker to have a low-privileged user account to initiate the attack.

Technologies: Open Identity Platform OpenAM Community Edition. Vendors: Maven, Open Identity Platform.

Am I affected by CVE-2026-45794?
Check whether you run org.openidentityplatform.openam:openam-push-notification (Maven) or Open Identity Platform OpenAM Community Edition at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

How to fix

  • org.openidentityplatform.openam:openam-push-notification (Maven): upgrade to 16.1.1 or later

Technical details

A Deserialization of Untrusted Data (CWE-502) exists in the OpenAM Push Notification SNS callback resource. The vulnerability occurs when a REST route handling SNS push messages, which is accessible anonymously, falls back to a persistent CTS-stored predicate blob after an in-memory dispatcher entry expires. An attacker with low-privileged access can plant a malicious blob by initiating a Push Registration. When the server later processes this blob, it treats top-level keys as Java class names and passes them to Class.forName() before deserializing attacker-controlled JSON via Jackson. This provides a class-loading and construction primitive that can lead to remote code execution, file writes, or DoS depending on the classpath. The issue is patched in version 16.1.1.
