Answer in brief
CVE-2026-52833 records a High severity (CVSS 8.0) vulnerability in Nuclio: Unsanitized runtimeAttributes.repositories injected into Groovy build.gradle leads to build-time RCE. The current sources do not mark it as known exploited. The current feed maps nuclio/nuclio (generic), github.com/nuclio/nuclio (go). Check affected ranges and fixed versions before updating.

Nuclio is a "Serverless" framework for Real-Time Events and Data Processing. Prior to version 1.16.5, Nuclio's Java runtime generates a build.gradle file during function builds using Go's text/template package. The template renders runtimeAttributes.repositories[] values with the {{ . }} action, which performs no escaping. An attacker can embed a closing brace (}) to break out of the repositories {} block and append arbitrary Groovy statements that execute unconditionally during the Gradle configuration phase. This issue has been patched in version 1.16.5.
