CVE-2022-31156Network attack vector

Dependency poisoning via skipped checksum fallback

Published Jul 14, 2022 · Updated Apr 23, 2025

Dependency verification bypass in Gradle Build Tool 6.2 through 7.4.2 allows attackers to introduce malicious build dependencies. For gpg-only metadata, the verifier accepts an artifact without a checksum when signatures are disabled or its remote signature file is absent. Exploitation requires control of a name-squatted repository artifact or interception of an HTTP repository connection, after which malicious code enters the build.
