{"cve":"CVE-2026-42074","nvd":{"published":"2026-06-02T17:16:32.073","modified":"2026-07-22T19:10:00.120","status":"Analyzed","description":"OpenClaude is an open-source coding-agent command line interface for cloud and local model providers. Prior to version 0.5.1, the dangerouslyDisableSandbox parameter is exposed as part of the BashTool input schema, meaning the LLM (an untrusted principal per the project's own threat model) can set it to true in any tool_use response. Combined with the default allowUnsandboxedCommands: true setting, a prompt-injected model can escape the sandbox for any arbitrary command, achieving full host-level code execution. This issue has been patched in version 0.5.1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-284","CWE-306"],"references":["https://github.com/Gitlawb/openclaude/commit/aab489055c53dd64369414116fe93226d2656273","https://github.com/Gitlawb/openclaude/pull/778","https://github.com/Gitlawb/openclaude/security/advisories/GHSA-m77w-p5jj-xmhg","https://github.com/Gitlawb/openclaude/security/advisories/GHSA-m77w-p5jj-xmhg"],"products":["gitlawb:openclaude"],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-42074","score":0.00589,"percentile":0.48169,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-m77w-p5jj-xmhg","url":"https://osv.dev/vulnerability/GHSA-m77w-p5jj-xmhg","summary":"OpenClaude Sandbox Bypass via Model-Controlled `dangerouslyDisableSandbox` Input","modified":"2026-06-09T11:15:08.685381516Z","packages":[{"ecosystem":"npm","name":"openclaude","purl":"pkg:npm/openclaude","ranges":["<0.5.1"],"fixed":["0.5.1"]}]}],"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).
