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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H","score":8.0},"cwes":["CWE-94"],"references":["https://github.com/nuclio/nuclio/commit/4c78040c759068e927f3ed7c6507543c15d4ae56","https://github.com/nuclio/nuclio/pull/4149","https://github.com/nuclio/nuclio/releases/tag/1.16.5","https://github.com/nuclio/nuclio/security/advisories/GHSA-3v79-m2cg-89ww","https://github.com/nuclio/nuclio/security/advisories/GHSA-3v79-m2cg-89ww"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-52833","score":0.00552,"percentile":0.46177,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-3v79-m2cg-89ww","url":"https://osv.dev/vulnerability/GHSA-3v79-m2cg-89ww","summary":"Nuclio: Unsanitized runtimeAttributes.repositories injected into Groovy build.gradle leads to build-time RCE","modified":"2026-07-21T19:18:54.329479600Z","packages":[{"ecosystem":"Go","name":"github.com/nuclio/nuclio","purl":"pkg:golang/github.com/nuclio/nuclio","ranges":["<1.16.5"],"fixed":["1.16.5"]}]},{"id":"GO-2026-6004","url":"https://osv.dev/vulnerability/GO-2026-6004","summary":"Nuclio: Unsanitized runtimeAttributes.repositories injected into Groovy build.gradle leads to build-time RCE in github.com/nuclio/nuclio","modified":"2026-07-21T19:15:35.981863135Z","packages":[{"ecosystem":"Go","name":"github.com/nuclio/nuclio","purl":"pkg:golang/github.com/nuclio/nuclio","ranges":["all versions"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
