{"id":"CVE-2026-35570","state":"PUBLISHED","title":"OpenClaude has Sandbox Bypass via Early-Exit Logic Flaw that Allows Path Traversal","description":"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.","publishedAt":"2026-04-20T23:24:08.324Z","updatedAt":"2026-04-21T19:49:30.148Z","severity":{"score":8.4,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["Gitlawb openclaude"],"affected":[{"vendor":"Gitlawb","product":"openclaude","versions":[{"version":"< 0.5.1","status":"affected"}]}],"references":["https://github.com/Gitlawb/openclaude/security/advisories/GHSA-m6rx-7pvw-2f73","https://github.com/Gitlawb/openclaude/commit/7002cb302b78ea2a19da3f26226de24e2903fa1d"],"weaknesses":["CWE-22","CWE-284"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/35xxx/CVE-2026-35570.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-35570","state":"PUBLISHED","datePublished":"2026-04-20T23:24:08.324Z","dateUpdated":"2026-04-21T19:49:30.148Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-04-03T20:09:02.826Z"},"containers":{"cna":{"title":"OpenClaude has Sandbox Bypass via Early-Exit Logic Flaw that Allows Path Traversal","descriptions":[{"lang":"en","value":"OpenClaude is an open-source coding-agent command line interface for cloud and local model providers.
