CVE-2021-21677
First published: Tue Aug 31 2021(Updated: )
Jenkins Code Coverage API Plugin 1.4.0 and earlier does not apply [JEP-200 deserialization protection](https://github.com/jenkinsci/jep/tree/master/jep/200) to Java objects it deserializes from disk. This results in a remote code execution (RCE) vulnerability exploitable by attackers able to control agent processes. Jenkins Code Coverage API Plugin 1.4.1 configures its Java object deserialization to only deserialize safe types.
