CVE-2025-48913Network attack vector

Authenticated code execution via unsafe JNDI provider URL

Published Aug 8, 2025 · Updated Feb 26, 2026

JNDI injection in Apache CXF before 3.6.8, 4.0.0 through 4.0.8, and 4.1.0 through 4.1.2 allows remote authenticated users to execute code. JndiHelper accepts attacker-controlled Context.PROVIDER_URL values and performs JNDI lookups through LDAP or RMI without rejecting these unsafe schemes. The flaw is reachable only when untrusted users can configure JMS; a crafted provider URL directs the host JVM to attacker-controlled JNDI content.
