SCA: security update for org.a2aproject.sdk:a2a-java-sdk-transport-rest (GHSA-x32g-jvvm-4725)

medium Tenable Cloud Security Plugin ID 476398

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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-2026-111762)

Solution

Update the org.a2aproject.sdk:a2a-java-sdk-transport-rest library and its related packages to version 1.3.0.Final or later.
