Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The a2a-java-sdk-transport-rest package before 1.3.0.Final logs entire request bodies when push notification configuration parsing fails. Anyone with server log access can read the bearer tokens and credentials in cleartext and use them to forge task updates. Upgrade to 1.3.0.Final or later.
