Payara 7.2026.1.RC1 Arbitrary EJB Method Invocation via Insecure Reflection in Payara Server
Payara Server 7.2026.1.RC1 HTTP EJB endpoints rely on attacker-controlled reflection and JNDI lookups without authorization, enabling arbitrary EJB method invocation.
Payara Server exposes multiple HTTP-accessible EJB invocation mechanisms that depend on attacker-controlled reflection, dynamic class loading, and unsafe deserialization. Remote clients can perform arbitrary JNDI lookups, resolve attacker-supplied class names, and invoke EJB business methods without sufficient authorization enforcement or input restriction. Both the deprecated InvokeEJBServlet and other endpoints are affected in version 7.2026.1.RC1.
