Doc Text:
A flaw was found in Gradle. When copying files or creating archives, Gradle does not preserve symbolic links, instead resolving them to their underlying target file, but permissions of the new file use those of the link instead of those from the target file. This issue can lead to files with broader permissions than intended, as symbolic links are usually world-readable and writeable.

Description Patrick Del Bello 2023-10-06 14:03:12 UTC 
Gradle is a build tool with a focus on build automation and support for multi-language development. When copying or archiving symlinked files, Gradle resolves them but applies the permissions of the symlink itself instead of the permissions of the linked file to the resulting file. This leads to files having too much permissions given that symlinks usually are world readable and writeable. While it is unlikely this results in a direct vulnerability for the impacted build, it may open up attack vectors depending on where build artifacts end up being copied to or un-archived. In versions 7.6.3, 8.4 and above, Gradle will now properly use the permissions of the file pointed at by the symlink to set permissions of the copied or archived file.
