Esa protecci\u00f3n bloquea nuevos \u00e1tomos, funciones y puertos, pero no una estructura construida a partir de \u00e1tomos ya internados en una aplicaci\u00f3n Ash en ejecuci\u00f3n, por lo que una expresi\u00f3n %Ash.Query.Call{} decodificada sobrevive y se inserta en el filtro del conjunto de claves como un valor de comparaci\u00f3n en do_filters/4 y se eval\u00faa. Debido a que el cursor omite la macro Ash.Expr, el tiempo de ejecuci\u00f3n nunca aplica la puerta private?/public? que de otro modo lo rechazar\u00eda. En AshPostgres, el fragmento inyectado se inserta en la consulta SQL; en las capas de datos ETS y Simple se eval\u00faa en el proceso como una llamada a funci\u00f3n arbitraria.\n\nEste problema afecta a ash: desde 1.17.0 antes de 3.31.3."}], "id": "CVE-2026-67579", "lastModified": "2026-10-24T16:10:00.153", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "HIGH", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "baseScore": 7.4, "baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1"}, "exploitabilityScore": 1.4, "impactScore": 5.9, "source": "nvd@nist.gov", "type": "Primary"}], "cvssMetricV40": [{"cvssData": {"Automatable": "NOT_DEFINED", "Recovery": "NOT_DEFINED", "Safety": "NOT_DEFINED", "attackComplexity": "LOW", "attackRequirements": "PRESENT", "attackVector": "LOCAL", "availabilityRequirement": "NOT_DEFINED", "baseScore": 7.5, "baseSeverity": "HIGH", "confidentialityRequirement": "NOT_DEFINED", "exploitMaturity": "NOT_DEFINED", "integrityRequirement": "NOT_DEFINED", "modifiedAttackComplexity": "NOT_DEFINED", "modifiedAttackRequirements": "NOT_DEFINED", "modifiedAttackVector": "NOT_DEFINED", "modifiedPrivilegesRequired": "NOT_DEFINED", "modifiedSubAvailabilityImpact": "NOT_DEFINED", "modifiedSubConfidentialityImpact": "NOT_DEFINED", "modifiedSubIntegrityImpact": "NOT_DEFINED", "modifiedUserInteraction": "NOT_DEFINED", "modifiedVulnAvailabilityImpact": "NOT_DEFINED", "modifiedVulnConfidentialityImpact": "NOT_DEFINED", "modifiedVulnIntegrityImpact": "NOT_DEFINED", "privilegesRequired": "NONE", "providerUrgency": "NOT_DEFINED", "subAvailabilityImpact": "NONE", "subConfidentialityImpact": "NONE", "subIntegrityImpact": "NONE", "userInteraction": "NONE", "valueDensity": "NOT_DEFINED", "vectorString": "CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/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", "version": "4.0", "vulnAvailabilityImpact": "HIGH", "vulnConfidentialityImpact": "HIGH", "vulnIntegrityImpact": "HIGH", "vulnerabilityResponseEffort": "NOT_DEFINED"}, "source": "6b3ad84c-e1a6-4bf7-a703-f496b71e49db", "type": "Secondary"}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2026-67579", "options": [{"exploitation": "poc"}, {"automatable": "no"}, {"technicalImpact": "total"}], "role": "CISA Coordinator", "timestamp": "2026-08-13T12:43:59.286788Z", "version": "2.0.3"}}]}, "published": "2026-08-12T20:17:48.440", "references": [{"source": "6b3ad84c-e1a6-4bf7-a703-f496b71e49db", "tags": ["Third Party Advisory", "Patch"], "url": "https://cna.erlef.org/cves/CVE-2026-67579.html"}, {"source": "6b3ad84c-e1a6-4bf7-a703-f496b71e49db", "tags": ["Patch"], "url": "https://github.com/ash-project/ash/commit/91874dd5435bc0ffebd8a254acfa573b39b74520"}, {"source": "6b3ad84c-e1a6-4bf7-a703-f496b71e49db", "tags": ["Vendor Advisory", "Exploit", "Patch"], "url": "https://github.com/ash-project/ash/security/advisories/GHSA-3gq3-9xm3-c8v3"}, {"source": "6b3ad84c-e1a6-4bf7-a703-f496b71e49db", "tags": ["Third Party Advisory", "Patch"], "url": "https://osv.dev/vulnerability/EEF-CVE-2026-67579"}, {"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "tags": ["Vendor Advisory", "Exploit", "Patch"], "url": "https://github.com/ash-project/ash/security/advisories/GHSA-3gq3-9xm3-c8v3"}], "sourceIdentifier": "6b3ad84c-e1a6-4bf7-a703-f496b71e49db", "vulnStatus": "Analyzed", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-89"}, {"lang": "en", "value": "CWE-502"}], "source": "6b3ad84c-e1a6-4bf7-a703-f496b71e49db", "type": "Secondary"}]}
