SCA: security update for org.openidentityplatform.openam:openam-auth-webauthn (GHSA-gf8h-gq53-288j)

critical Tenable Self-Hosted Container Security Plugin ID 445369

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Open Access Management (OpenAM) is an access management solution. Prior to 16.1.2,
 WebAuthnAuthentication.deserialize applies an ObjectInputFilter that allows every serialized object at
 depth greater than 1 and therefore constrains only an AuthenticatorImpl root object. A pre-authentication
 attacker can supply a userHandle whose serialized graph has a valid AuthenticatorImpl root and a nested
 gadget class, causing readObject or readResolve execution before the cast and assertion verification when
 a usable gadget is on the classpath. This bypasses the incomplete remediation for the earlier WebAuthn
 deserialization vulnerability. This issue is fixed in version 16.1.2. (CVE-2026-62263)

Solution

Update the org.openidentityplatform.openam:openam-auth-webauthn library and its related packages to version 16.1.2 or later.
