This affects the package com.diffplug.gradle:goomph before 3.37.2. It allows a malicious zip file to potentially break out of the expected destination directory, writing contents into arbitrary locations on the file system. Overwriting certain files/directories could allow an attacker to achieve remote code execution on a target system by exploiting this vulnerability. **Note:** This could have allowed a malicious zip file to extract itself into an arbitrary directory. The only file that Goomph extracts is the p2 bootstrapper and eclipse metadata files hosted at eclipse.org, which are not malicious, so the only way this vulnerability could have affected you is if you had set a custom bootstrap zip, and that zip was malicious.

In all versions prior to version 3.9.6 for eclipse-wtp, all versions prior to version 9.4.4 for eclipse-cdt, and all versions prior to version 3.0.1 for eclipse-groovy, Spotless was resolving dependencies over an insecure channel (http). If the build occurred over an insecure connection, a malicious user could have perform a Man-in-the-Middle attack during the build and alter the build artifacts that were produced. In case that any of these artifacts were compromised, any developers using these could be altered. **Note:** In order to validate that this artifact was not compromised, the maintainer would need to confirm that none of the artifacts published to the registry were not altered with. Until this happens, we can not guarantee that this artifact was not compromised even though the probability that this happened is low.

In DiffPlug Spotless before 1.20.0 (library and Maven plugin) and before 3.20.0 (Gradle plugin), the XML parser would resolve external entities over both HTTP and HTTPS and didn't respect the resolveExternalEntities setting. For example, this allows disclosure of file contents to a MITM attacker if a victim performs a spotlessApply operation on an untrusted XML file.
