8.0 highCVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:HCVE-2026-52833
High (8.0). EPSS 0.6% chance of exploitation in the next 30 days. Fixed in github.com/nuclio/nuclio 1.16.5.
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.
