GHSA-3v79-m2cg-89ww: github.com/nuclio/nuclio (CVE-2026-52833)

Package	Ecosystem	Affected	Fixed in
github.com/nuclio/nuclio	Go	<1.16.5	1.16.5

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Nuclio versions before 1.16.5 are vulnerable to code injection during Java function builds: the repositories value in runtimeAttributes is written unescaped into a generated Gradle build.gradle file, so an attacker can break out of the block and run arbitrary Groovy. The source says the Dashboard API accepts unauthenticated requests by default, so an attacker with network access to it can run OS commands as root in the build container. Upgrade to Nuclio 1.16.5 or later.
