Description Pedro Sampaio 2020-07-31 19:25:20 UTC

A flaw was found in spring-batch before version 4.2.3. When configured to enable default typing, Jackson contained a deserialization vulnerability that was fixed y by blacklisting known "deserialization gadgets". Spring Batch configures Jackson with global default typing enabled which means that through the previously mentioned exploit, arbitrary code could be executed at certain conditions.
