Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Seata seata-core versions 2.0.0 and 1.0.0 through 1.8.0 are vulnerable to unsafe deserialization of untrusted data. An attacker who can reach a Seata-Server that has authentication disabled, and who does not depend on the Seata client SDK, can send crafted serialized requests over the Seata protocol, which may allow malicious code to run. Upgrade seata-core to 2.1.0 or 1.8.1.
