Last modified

CVE-2026-75598 is a medium-severity vulnerability rated 6.3/10 on the CVSS scale. 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. EPSS estimates a 0.14% chance of exploitation in the next 30 days.

Description

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.
