{"id":"CVE-2026-35570","aliases":["GHSA-m6rx-7pvw-2f73"],"url":"https://o3.security/vulnerability/CVE-2026-35570","summary":"OpenClaude has Sandbox Bypass via Early-Exit Logic Flaw that Allows Path Traversal","details":"OpenClaude is an open-source coding-agent command line interface for cloud and local model providers. Versions prior to 0.5.1 have a logic flaw in `bashToolHasPermission()` inside `src/tools/BashTool/bashPermissions.ts`. When the sandbox auto-allow feature is active and no explicit deny rule is configured, the function returns an `allow` result immediately — before the path constraint filter (`checkPathConstraints`) is ever evaluated. This allows commands containing path traversal sequences (e.g., `../../../../../etc/passwd`) to bypass directory restrictions entirely. Version 0.5.1 contains a patch for the issue.","published":"2026-04-20T23:24:08.324Z","modified":"2026-07-15T01:48:58.310247017Z","cvss":{"score":8.4,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@gitlawb/openclaude","fixedVersion":"0.5.1"}],"fix":{"url":"https://github.com/Gitlawb/openclaude/commit/7002cb302b78ea2a19da3f26226de24e2903fa1d","label":"Gitlawb/openclaude@7002cb3"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35570.json"},{"type":"ADVISORY","url":"https://github.com/Gitlawb/openclaude/security/advisories/GHSA-m6rx-7pvw-2f73"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35570"},{"type":"FIX","url":"https://github.com/Gitlawb/openclaude/commit/7002cb302b78ea2a19da3f26226de24e2903fa1d"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:48:58.310247017Z"}}
