Prior to version 2.0.28, NocoBase's Workflow Script Node executes user-supplied JavaScript inside a Node.js vm sandbox with a custom require allowlist (controlled by WORKFLOW_SCRIPT_MODULES env var). However, the console object passed into the sandbox context exposes host-realm WritableWorkerStdio stream objects via console._stdout and console._stderr. An authenticated attacker can traverse the prototype chain to escape the sandbox and achieve Remote Code Execution as root. This issue has been patched in version 2.0.28.","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-34156","reference_id":"","reference_type":"","scores":[{"value":"0.32413","scoring_system":"epss","scoring_elements":"0.96965","published_at":"2026-06-11T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-34156"},{"reference_url":"https://github.com/nocobase/nocobase","reference_id":"","reference_type":"","scores":[{"value":"9.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/nocobase/nocobase"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34156","reference_id":"","reference_type":"","scores":[{"value":"9.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34156"},{"reference_url":"https://github.com/nocobase/nocobase/pull/8967","reference_id":"8967","reference_type":"","scores":[{"value":"10","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},{"value":"9.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track*","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:Y/T:T/P:M/B:A/M:M/D:R/2026-04-02T15:08:26Z/"}],"url":"https://github.com/nocobase/nocobase/pull/8967"},{"reference_url":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/multiple/local/52552.py","reference_id":"CVE-2026-34156","reference_type":"exploit","scores":[],"url":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/multiple/local/52552.py"},{"reference_url":"https://github.com/advisories/GHSA-px3p-vgh9-m57c","reference_id":"GHSA-px3p-vgh9-m57c","reference_type":"","scores":[],"url":"https://github.com/advisories/GHSA-px3p-vgh9-m57c"},{"reference_url":"https://github.com/nocobase/nocobase/security/advisories/GHSA-px3p-vgh9-m57c","reference_id":"GHSA-px3p-vgh9-m57c","reference_type":"","scores":[{"value":"10","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},{"value":"9.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track*","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:Y/T:T/P:M/B:A/M:M/D:R/2026-04-02T15:08:26Z/"}],"url":"https://github.com/nocobase/nocobase/security/advisories/GHSA-px3p-vgh9-m57c"},{"reference_url":"https://github.com/nocobase/nocobase/releases/tag/v2.0.28","reference_id":"v2.0.28","reference_type":"","scores":[{"value":"10","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},{"value":"9.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track*","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:Y/T:T/P:M/B:A/M:M/D:R/2026-04-02T15:08:26Z/"}],"url":"https://github.com/nocobase/nocobase/releases/tag/v2.0.28"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/374520?format=json","purl":"pkg:npm/%40nocobase/plugin-workflow-javascript@2.0.28","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540nocobase/plugin-workflow-javascript@2.0.28"}],"aliases":["CVE-2026-34156","GHSA-px3p-vgh9-m57c"],"risk_score":null,"exploitability":null,"weighted_severity":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-bpqh-1b2j-b3ct"}],"fixing_vulnerabilities":[],"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540nocobase/plugin-workflow-javascript@2.0.14"}
