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."},{"lang":"es","value":"OpenClaude es una interfaz de línea de comandos de agente de codificación de código abierto para proveedores de modelos locales y en la nube. Las versiones anteriores a la 0.5.1 tienen un fallo lógico en “bashToolHasPermission()” dentro de “src/tools/BashTool/bashPermissions.ts”. Cuando la función de auto-permiso del sandbox está activa y no hay una regla de denegación explícita configurada, la función devuelve un resultado de “allow” inmediatamente - antes de que el filtro de restricción de ruta (“checkPathConstraints”) sea evaluado. Esto permite que los comandos que contienen secuencias de salto de ruta (por ejemplo, “.. / .. / .. / .. / .. / etc/p4ssd”) eludan por completo las restricciones de directorio. La versión 0.5.1 contiene un parche para el problema."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"Gitlawb","product":"openclaude","versions":[{"version":"< 0.5.1","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","baseScore":8.4,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":2.0,"impactScore":5.8}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-04-21T16:01:46.877935Z","id":"CVE-2026-35570","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-22"},{"lang":"en","value":"CWE-284"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:gitlawb:openclaude:*:*:*:*:*:*:*:*","versionEndExcluding":"0.5.1","matchCriteriaId":"F2107920-62CC-4630-84F0-724AB1B17015"}]}]}],"references":[{"url":"https://github.com/Gitlawb/openclaude/commit/7002cb302b78ea2a19da3f26226de24e2903fa1d","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/Gitlawb/openclaude/security/advisories/GHSA-m6rx-7pvw-2f73","source":"security-advisories@github.com","tags":["Exploit","Mitigation","Vendor Advisory"]},{"url":"https://github.com/Gitlawb/openclaude/security/advisories/GHSA-m6rx-7pvw-2f73","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Exploit","Mitigation","Vendor Advisory"]}]}
