Antes de la versi\u00f3n 1.2.3, las plantillas inseguras del lado del servidor pueden ser secuestradas para exponer informaci\u00f3n segura al cliente. Al generar c\u00f3digos de lote personalizados, el servidor InvenTree utiliza una plantilla jinja2 personalizable, que puede ser modificada por un usuario del personal para exfiltrar informaci\u00f3n sensible o realizar ejecuci\u00f3n de c\u00f3digo en el servidor. Este problema requiere acceso por parte de un usuario con permisos de personal concedidos, seguido de una solicitud para generar un c\u00f3digo de lote personalizado a trav\u00e9s de la API. Una vez que la plantilla ha sido modificada de manera maliciosa, otros usuarios podr\u00edan llamar a la API para generar un nuevo c\u00f3digo de lote, y el c\u00f3digo de la plantilla se ejecutar\u00e1 con su contexto de usuario. El c\u00f3digo ha sido parcheado para asegurar que toda la generaci\u00f3n de plantillas se realice dentro de un contexto seguro en un entorno aislado. Este problema ha sido abordado en la versi\u00f3n 1.2.3, y en cualquier versi\u00f3n a partir de la 1.3.0. Hay disponibles algunas soluciones alternativas. La plantilla de c\u00f3digo de lote es una configuraci\u00f3n global configurable que puede ser ajustada por cualquier usuario con acceso de personal. Para evitar que esta configuraci\u00f3n sea editada, puede ser anulada a nivel de sistema a un valor predeterminado, evitando que sea editada. Esto requiere acceso de administrador de sistema, y no puede ser cambiado desde el lado del cliente una vez que el servidor est\u00e1 en funcionamiento. Se recomienda que para las instalaciones de InvenTree anteriores a la 1.2.3, se anulen las configuraciones globales 'STOCK_BATCH_CODE_TEMPLATE' y 'PART_NAME_FORMAT' a nivel de sistema para evitar su edici\u00f3n."}], "id": "CVE-2026-27629", "lastModified": "2026-06-17T10:27:25.167", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "ADJACENT_NETWORK", "availabilityImpact": "LOW", "baseScore": 5.9, "baseSeverity": "MEDIUM", "confidentialityImpact": "LOW", "integrityImpact": "LOW", "privilegesRequired": "LOW", "scope": "CHANGED", "userInteraction": "REQUIRED", "vectorString": "CVSS:3.1/AV:A/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L", "version": "3.1"}, "exploitabilityScore": 1.7, "impactScore": 3.7, "source": "security-advisories@github.com", "type": "Secondary"}, {"cvssData": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 8.8, "baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "REQUIRED", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H", "version": "3.1"}, "exploitabilityScore": 2.8, "impactScore": 5.9, "source": "nvd@nist.gov", "type": "Primary"}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2026-27629", "options": [{"exploitation": "none"}, {"automatable": "no"}, {"technicalImpact": "partial"}], "role": "CISA Coordinator", "timestamp": "2026-02-26T21:06:58.547845Z", "version": "2.0.3"}}]}, "published": "2026-02-25T03:16:06.680", "references": [{"source": "security-advisories@github.com", "tags": ["Mitigation", "Vendor Advisory"], "url": "https://github.com/inventree/InvenTree/security/advisories/GHSA-cx85-vr3q-9x4m"}], "sourceIdentifier": "security-advisories@github.com", "vulnStatus": "Analyzed", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-1336"}], "source": "security-advisories@github.com", "type": "Secondary"}]}

Through this misuse, a malicious template can access server\u2011side secrets or execute arbitrary code when the template is rendered via an API call by any user. The attack does not require network\u2011level access beyond normal API usage; it exploits a logical flaw in user privilege handling and template evaluation.", "risk_and_exploitability": "The CVSS score of 5.9 indicates a medium severity vulnerability. The EPSS score of less than 1 percent reflects a very low current exploitation probability, and the issue is not listed in CISA\u2019s KEV catalogue. The likely attack vector is via a local or remote API request to the batch generation endpoint that requires the attacker to have initially staff\u2011level credentials to alter the template. Attack feasibility requires staff\u2011level permissions to modify the template, after which any user can trigger the harmful code via the batch\u2011generation API. Once the template has been corrupted, the malicious code is executed with the context of the calling user, potentially compromising confidentiality, integrity, or availability of server resources depending on the injected operations."}}}}, "created": "2026-02-25T11:34:55.389109+00:00", "updated": "2026-04-18T11:00:05.734148+00:00", "vendors": ["inventree", "inventree$PRODUCT$inventree"]}
