SCA: security update for org.zeroturnaround:zt-zip (GHSA-52c6-99qm-3hqr)

medium Tenable Cloud Security Plugin ID 478834

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - zt-zip is a Java library that provides convenience methods for ZIP archive manipulation. Prior to 1.18.0,
 the Zips.get(zip).unpack().destination(outputDir).process() fluent API in
 src/main/java/org/zeroturnaround/zip/Zips.java constructs output files directly from ZIP entry names
 without applying the destination-boundary validation used by ZipUtil.unpack(...). A crafted entry
 containing parent-directory traversal can therefore write outside outputDir through both the normal copy
 branch and the ZipEntryTransformer branch. Applications that extract untrusted archives only through
 ZipUtil.unpack(...) are unaffected because that API already calls checkDestinationFileForTraversal. This
 issue is fixed in version 1.18.0. (CVE-2026-63436)

Solution

Update the org.zeroturnaround:zt-zip library and its related packages to version 1.18.0 or later.
