CVE-2026-75598	Medium	2026-11-06	Protected by Waratek	Proof of concept only	The Gradle Shadow plugin creates fat or uber JARs and supports file transformation and package relocation. Prior to version 9.6.0, Shadow does not independently validate ZIP entry names before writing them to its output archive. A malicious dependency can cause traversal entry names to be preserved when the applicable archive-processing path does not reject them. Some affected Shadow implementations process dependency archives directly, so upgrading Gradle alone does not universally prevent this behavior. If the resulting archive is extracted without path traversal protection, attacker-controlled files can be written outside the intended destination. This issue is fixed in version 9.6.0.

Proof of concept only

The Gradle Shadow plugin creates fat or uber JARs and supports file transformation and package relocation. Prior to version 9.6.0, Shadow does not independently validate ZIP entry names before writing them to its output archive. A malicious dependency can cause traversal entry names to be preserved when the applicable archive-processing path does not reject them. Some affected Shadow implementations process dependency archives directly, so upgrading Gradle alone does not universally prevent this behavior. If the resulting archive is extracted without path traversal protection, attacker-controlled files can be written outside the intended destination. This issue is fixed in version 9.6.0.

No public exploit

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.
