Se ha identificado una vulnerabilidad de seguridad en la CLI de GitHub que podr\u00eda filtrar tokens de autenticaci\u00f3n al clonar repositorios que contienen subm\u00f3dulos `git` alojados fuera de GitHub.com y ghe.com. Esta vulnerabilidad se origina en varios comandos `gh` utilizados para clonar un repositorio con subm\u00f3dulos de un host que no es de GitHub, incluidos `gh repo clone`, `gh repo fork` y `gh pr checkout`. Estos comandos de la CLI de GitHub invocan git con instrucciones para recuperar tokens de autenticaci\u00f3n utilizando la variable de configuraci\u00f3n `credential.helper` para cualquier host encontrado. Antes de la versi\u00f3n `2.63.0`, los hosts que no sean GitHub.com y ghe.com se tratan como hosts de GitHub Enterprise Server y tienen tokens provenientes de las siguientes variables de entorno antes de recurrir a tokens espec\u00edficos del host almacenados dentro de un almacenamiento seguro espec\u00edfico del sistema: 1. `GITHUB_ENTERPRISE_TOKEN`, 2. `GH_ENTERPRISE_TOKEN` y 3. `GITHUB_TOKEN` cuando se establece la variable de entorno `CODESPACES`. El resultado es que `git` env\u00eda tokens de autenticaci\u00f3n al clonar subm\u00f3dulos. En la versi\u00f3n `2.63.0`, estos comandos de la CLI de GitHub limitar\u00e1n los hosts para los que `gh` act\u00faa como un asistente de credenciales para obtener tokens de autenticaci\u00f3n. Adem\u00e1s, `GITHUB_TOKEN` solo se usar\u00e1 para GitHub.com y ghe.com. Se recomienda a los usuarios que actualicen. Adem\u00e1s, se recomienda a los usuarios revocar los tokens de autenticaci\u00f3n utilizados con la CLI de GitHub y revisar su registro de seguridad personal y cualquier registro de auditor\u00eda relevante para las acciones asociadas con su cuenta o empresa."}], "id": "CVE-2024-53858", "lastModified": "2026-06-17T08:09:25.557", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "HIGH", "attackVector": "LOCAL", "availabilityImpact": "LOW", "baseScore": 6.5, "baseSeverity": "MEDIUM", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "REQUIRED", "vectorString": "CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:L", "version": "3.1"}, "exploitabilityScore": 1.0, "impactScore": 5.5, "source": "security-advisories@github.com", "type": "Secondary"}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2024-53858", "options": [{"exploitation": "none"}, {"automatable": "no"}, {"technicalImpact": "total"}], "role": "CISA Coordinator", "timestamp": "2024-12-03T15:02:11.542915Z", "version": "2.0.3"}}]}, "published": "2024-11-27T22:15:05.520", "references": [{"source": "security-advisories@github.com", "url": "https://git-scm.com/docs/gitcredentials"}, {"source": "security-advisories@github.com", "url": "https://github.com/cli/cli/security/advisories/GHSA-jwcm-9g39-pmcw"}], "sourceIdentifier": "security-advisories@github.com", "vulnStatus": "Deferred", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-200"}], "source": "security-advisories@github.com", "type": "Secondary"}]}
