Vulnerability in com.mchange:mchange-commons-java (CVE-2026-55153)
Summary
Vulnerability in com.mchange:mchange-commons-java (CVE-2026-55153). Successful exploitation can lead to full system takeover. Exploitable via ObjectFactory. Mitigation: upgrade to 0.6.0 or later.
Original description
The description as published by the source.
mchange-commons-java is a Java library of shared utility classes used by mchange projects like the c3p0 connection pool. Prior to version 0.6.0, its JNDI ObjectFactory implementation (com.mchange.v2.naming.JavaBeanObjectFactory) will construct objects of arbitrary classes and initialize "JavaBean"-style properties, which for certain classes enables JNDI injection and "deserialization gadgets." Such initialization is unsafe for some classes: for example, setting the contentType property of a Swing JEditorPane to text/html and its text property to HTML containing a stylesheet will provoke an HTTP GET on an arbitrary URL, potentially from within a trusted security domain. The problem is aggravated by the library's ReferenceIndirector, through which malicious JNDI Reference objects can be smuggled in for dereferencing wherever an application reads a Java-serialized object. This has been resolved in version 0.6.0.
