medium Tenable Self-Hosted Container Security Plugin ID 444280

Description

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

 - A flaw was found in Keycloak. A remote attacker with high privileges, such as a realm administrator
 configuring a malicious Lightweight Directory Access Protocol (LDAP) server or an attacker compromising an
 upstream LDAP server, could exploit this vulnerability. By sending a malformed LDAP password policy
 response during a password authentication request, the attacker can trigger an OutOfMemoryError. This
 causes the Keycloak Java Virtual Machine (JVM) to terminate, leading to a denial of service (DoS) for all
 realms on the affected node. (CVE-2026-9801)
