AI-suggested

A fix is available in version 9.6.0 of the Gradle Shadow plugin. Users should upgrade to version 9.6.0 or later to remediate this vulnerability. Until upgraded, users should ensure that downstream consumers of shadow JARs use extraction tools that protect against Zip Slip path traversal attacks. No other vendor advisory mitigation instructions are provided.

Description

The Gradle Shadow plugin's ShadowCopyAction does not sanitize ZIP entry names before including them in the output fat JAR, allowing path traversal entries to be reproduced verbatim. This vulnerability affects versions prior to 9.6.0. Malicious dependencies with crafted ZIP entries can cause arbitrary file overwrite when the shadow JAR is extracted by downstream tools that do not protect against Zip Slip attacks.
