CVE-2026-111762	Medium	2026-10-20	Protected by Waratek	No public exploit	A2A Java SDK is the official Java SDK for the Agent2Agent (A2A) Protocol. Prior to 1.3.0.Final, RestHandler.parseRequestBody in `transport/rest/src/main/java/org/a2aproject/sdk/transport/rest/handler/RestHandler.java` logs the entire JSON request body at SEVERE level when JsonFormat.parser().merge() throws InvalidProtocolBufferException. With push notifications enabled, createTaskPushNotificationConfiguration reaches this parser for requests to `/v1/tenants/{tenant}/tasks/{taskId}/pushNotificationConfigs`, whose token and authentication.credentials fields can contain bearer tokens and authentication credentials for client push endpoints. A valid JSON body that fails protobuf deserialization, including an unknown field under strict parsing or a schema mismatch, causes those secrets to be written to the server logs in cleartext. An attacker with access to the server logs or a log aggregation system can retrieve the credentials and potentially use the credentials to send forged task status updates to the client's push notification endpoint. This issue is fixed in version 1.3.0.Final.
CVE-2026-55153	High	2026-07-01	Protected by Waratek	No public exploit	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 <link> 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.
