Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Zeppelin (org.apache.zeppelin:zeppelin-interpreter) versions 0.8.2 up to but not including 0.11.1 are affected by an improper encoding or escaping of output vulnerability. The source describes an attacker being able to execute shell scripts or malicious code by overriding the ZEPPELIN_INTP_CLASSPATH_OVERRIDES configuration, but gives few details on the required access. Upgrade to Apache Zeppelin 0.11.1, which fixes the issue.
