Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

mchange-commons-java versions before 0.6.0 are vulnerable. The JNDI ObjectFactory in com.mchange.v2.naming.JavaBeanObjectFactory can be made to construct arbitrary classes and set JavaBean properties, and it deserialized Java objects in earlier releases, so an attacker who can supply a malicious JNDI reference or serialized object can trigger outbound requests or possibly run commands. Upgrade to mchange-commons-java 0.6.0 or later; the source notes that upgrading c3p0 to 0.14.0 or later also brings in a patched version.
