Attackers can exploit overly permissive environment variable allowlisting in repo-local Crabbox configuration to serialize sensitive environment variables into remote command execution, exposing credentials to the remote environment."},{"lang":"es","value":"Crabbox anterior a la v0.12.0 contiene una vulnerabilidad de exposición de variables de entorno que permite a los atacantes con acceso a un repositorio malicioso o comprometido reenviar secretos locales como tokens de API, credenciales de la nube y tokens de bróker al entorno de comandos remoto. Los atacantes pueden explotar una lista blanca de variables de entorno excesivamente permisiva en la configuración de Crabbox local del repositorio para serializar variables de entorno sensibles en la ejecución remota de comandos, exponiendo credenciales al entorno remoto."}],"affected":[{"source":"disclosure@vulncheck.com","affectedData":[{"vendor":"openclaw","product":"crabbox","defaultStatus":"affected","repo":"https://github.com/openclaw/crabbox","packageURL":"pkg:golang/github.com/openclaw/crabbox","versions":[{"version":"0","lessThan":"0.12.0","versionType":"semver","status":"affected"},{"version":"eaae40ae4ce009e60633f16f7f19600c74557f6f","versionType":"git","status":"unaffected"}]}]}],"metrics":{"cvssMetricV40":[{"source":"disclosure@vulncheck.com","type":"Secondary","cvssData":{"version":"4.0","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","baseScore":9.3,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"NONE","userInteraction":"NONE","vulnConfidentialityImpact":"HIGH","vulnIntegrityImpact":"HIGH","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","exploitMaturity":"NOT_DEFINED","confidentialityRequirement":"NOT_DEFINED","integrityRequirement":"NOT_DEFINED","availabilityRequirement":"NOT_DEFINED","modifiedAttackVector":"NOT_DEFINED","modifiedAttackComplexity":"NOT_DEFINED","modifiedAttackRequirements":"NOT_DEFINED","modifiedPrivilegesRequired":"NOT_DEFINED","modifiedUserInteraction":"NOT_DEFINED","modifiedVulnConfidentialityImpact":"NOT_DEFINED","modifiedVulnIntegrityImpact":"NOT_DEFINED","modifiedVulnAvailabilityImpact":"NOT_DEFINED","modifiedSubConfidentialityImpact":"NOT_DEFINED","modifiedSubIntegrityImpact":"NOT_DEFINED","modifiedSubAvailabilityImpact":"NOT_DEFINED","Safety":"NOT_DEFINED","Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","valueDensity":"NOT_DEFINED","vulnerabilityResponseEffort":"NOT_DEFINED","providerUrgency":"NOT_DEFINED"}}],"cvssMetricV31":[{"source":"disclosure@vulncheck.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","baseScore":9.1,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":5.2}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-05-15T14:16:23.398053Z","id":"CVE-2026-8634","options":[{"exploitation":"poc"},{"automatable":"yes"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"disclosure@vulncheck.com","type":"Secondary","description":[{"lang":"en","value":"CWE-94"}]}],"references":[{"url":"https://github.com/openclaw/crabbox/commit/eaae40ae4ce009e60633f16f7f19600c74557f6f","source":"disclosure@vulncheck.com"},{"url":"https://github.com/openclaw/crabbox/pull/78","source":"disclosure@vulncheck.com"},{"url":"https://github.com/openclaw/crabbox/releases/tag/v0.12.0","source":"disclosure@vulncheck.com"},{"url":"https://www.vulncheck.com/advisories/crabbox-environment-variable-information-disclosure","source":"disclosure@vulncheck.com"},{"url":"https://github.com/openclaw/crabbox/pull/78","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}
