SCA: security update for org.a2aproject.sdk:a2a-java-sdk-http-client-android (GHSA-4fpj-g9jf-9rgg)

high Tenable Cloud Security Plugin ID 476403

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. Starting in version 1.3.0.Final
 and prior to version 1.3.2.Final, the AndroidA2AHttpClient synchronous POST path overrides the disabled-
 redirect setting in AndroidA2AHttpClient.createConnection() with the PostBuilder default followRedirects
 value of true, leaving a residual of the earlier credential-redirect fix. JSONRPCTransport and
 RestTransport add interceptor-produced authentication headers and call synchronous post() without
 disabling redirects. AuthInterceptor permits X-API-Key, API-Key, X-Auth-Token, and X-Authentication
 headers; Android's repackaged OkHttp strips Authorization on cross-authority redirects but retains these
 nonstandard headers, disclosing a complete configured API key or token to another authority. The
 additional exposure applies when redirect or front-door behavior is compromised separately from the
 credential-handling component, or those components operate in different trust domains; a completely
 malicious initial origin already receives the credential on the first request. Autonomous clients require
 no human action, while user-invoked workflows can require interaction. Explicit followRedirects(false)
 prevents the redirected request. The demonstrated impact is credential disclosure, not subsequent
 credential use, integrity or availability impact, code execution, or host compromise. This issue is fixed
 in version 1.3.2.Final. (CVE-2026-111765)

Solution

Update the org.a2aproject.sdk:a2a-java-sdk-http-client-android library and its related packages to version 1.3.2.Final or later.
