CVE-2026-52833Public exploitNetwork attack vectorHinoki check available

Root command execution via unescaped Gradle repositories

Published Sep 2, 2026 · Updated Sep 2, 2026

Code injection in Iguazio Nuclio before 1.16.5 allows remote attackers to execute commands as root during Java function builds. The Java build path's createGradleBuildScript function renders runtimeAttributes.repositories entries verbatim into build.gradle, letting a closing brace escape the repositories block and append top-level Groovy statements. Default Dashboard API deployments accept function creation without authentication; execution occurs in the root build container and can alter the function artifact.
